How Much Does A Shot Glass Hold: a standard U.S. shot glass holds 1.5 fluid ounces, or 3 tablespoons. That equals about 44 milliliters. In recipes, “1 shot” usually means 1.5 fl oz unless the recipe names a different measure.
Shot glasses are not all the same size. Small bar glasses may hold 1 fl oz, while larger ones may hold 2 fl oz or more when filled to the rim. For accurate cooking or cocktail measuring, use a jigger or liquid measuring spoon, not the glass’s rim.
A standard U.S. shot glass holds 1.5 fluid ounces, equal to 3 tablespoons or about 44 milliliters. Some shot glasses hold 1 ounce or 2 ounces, so check the marking if accuracy matters.
The Short Answer
A standard U.S. shot is usually 1.5 fluid ounces. That equals 44.36 mL, 3 tablespoons, or 9 teaspoons.
The glass itself may hold more or less. A “shot glass” can be 1 oz, 1.25 oz, 1.5 oz, or 2 oz, so the useful answer is: measure the liquid, not the rim.
| Measure | Fluid ounces | Milliliters | Kitchen equivalent |
|---|---|---|---|
| Small shot | 1 fl oz | 29.57 mL | 2 tbsp |
| Common U.S. shot | 1.5 fl oz | 44.36 mL | 3 tbsp |
| Large shot | 2 fl oz | 59.15 mL | 4 tbsp |
| Half shot | 0.75 fl oz | 22.18 mL | 1.5 tbsp |
What to Use in a Recipe
If a U.S. recipe says “1 shot” and gives no other detail, use 1.5 fl oz. In kitchen terms, pour 3 tablespoons.
Example: a sauce calls for 2 shots of bourbon. Use 3 fl oz total, which is 6 tablespoons or about 88.7 mL.
Example: a cocktail calls for 1 shot of tequila and 1 half-shot of lime juice. That is 1.5 fl oz tequila plus 0.75 fl oz lime juice.
Total liquid in that example is 2.25 fl oz, or about 66.5 mL. In spoons, that is 4.5 tablespoons.
Why Your Shot Glass May Not Match
Many souvenir shot glasses are made to look full at 1 oz, not 1.5 oz. Others hold 2 oz to the brim, leaving room for a measured 1.5 oz pour.
Do not assume “filled to the top” equals one shot. If the glass holds 2 oz to the rim, a standard 1.5 oz shot fills only 75% of it.
If the glass holds 1 oz to the rim, filling it once gives only two-thirds of a standard U.S. shot. You would need 1.5 full glasses.
A double shot is commonly 3 fl oz when based on the 1.5 oz U.S. shot. That equals 6 tablespoons, or about 88.7 mL.
For accuracy, use a liquid measuring cup, measuring spoons, or a jigger marked in ounces or milliliters. The most reliable number for “a shot” in U.S. home recipes is 1.5 fl oz.
Standard Shot Glass Ounces
In the United States, a standard shot glass usually holds 1.5 fluid ounces. That equals 3 tablespoons, 9 teaspoons, or about 44 milliliters.
The key word is “usually.” Shot glasses are not federally standardized drinkware. A glass sold as a shot glass may hold 1 ounce, 1.25 ounces, 1.5 ounces, 2 ounces, or more when filled to the rim.
Common Shot Glass Sizes
| Shot size | Fluid ounces | Milliliters | Tablespoons |
|---|---|---|---|
| Small shot | 1 oz | 30 mL | 2 tbsp |
| Common U.S. shot | 1.5 oz | 44 mL | 3 tbsp |
| Large shot | 2 oz | 59 mL | 4 tbsp |
| Double shot | 3 oz | 89 mL | 6 tbsp |
For cooking and mixing, use 1 shot = 1.5 fluid ounces unless a recipe says otherwise. That conversion is the safest default for U.S. recipes and bar-style measurements.
Example: if a punch recipe calls for 4 shots of rum, calculate 4 × 1.5 oz. The result is 6 fluid ounces, or 3/4 cup.
Example: if a sauce calls for 2 shots of whiskey, use 2 × 1.5 oz. That equals 3 fluid ounces, or 6 tablespoons.
Filled To The Line Vs Filled To The Rim
Many shot glasses have a thick base and a flared lip. A “1.5 oz” shot glass may measure 1.5 oz to an invisible practical pour line, but closer to 1.75 or 2 oz when filled to the brim.
If accuracy matters, do not rely on the glass shape. Measure once with water: pour the glass into a liquid measuring cup or count tablespoons. One tablespoon is 0.5 fluid ounce.
A fast check: 2 tablespoons means a 1 oz shot. 3 tablespoons means a 1.5 oz shot. 4 tablespoons means a 2 oz shot.
Mini, Tall, And Novelty Shot Glasses
A mini shot glass may hold only 0.75 to 1 ounce. These are common in tasting sets, souvenir packs, and dessert servings.
A tall narrow shot glass can look larger than it is. Some hold exactly 1 ounce, while heavier, wider versions may hold 2 ounces.
Novelty shot glasses are the least reliable. Skulls, boots, mason jars, and tilted designs often have decorative glass that changes the true liquid capacity.
Best Practical Answer
For a normal U.S. shot, use 1.5 fluid ounces. For a double shot, use 3 fluid ounces. For a recipe that says “one shot” without detail, measure 3 tablespoons.
If the amount affects flavor, alcohol strength, or baking texture, measure the liquid instead of eyeballing the shot glass. A kitchen tablespoon gives a more exact result than most barware.
Shot Sizes By Country
A “shot” is not one worldwide amount. In bars and recipes, it usually means 25 ml, 30 ml, 35 ml, 40 ml, 44 ml, or 50 ml, depending on the country and house pour.
| Country | Common shot size | Approx. US fl oz |
|---|---|---|
| United States | 44 ml | 1.5 fl oz |
| United Kingdom | 25 ml or 35 ml | 0.85 or 1.18 fl oz |
| Ireland | 35.5 ml | 1.2 fl oz |
| Canada | 30 ml or 44 ml | 1.0 or 1.5 fl oz |
| Australia | 30 ml | 1.0 fl oz |
| New Zealand | 30 ml | 1.0 fl oz |
| Germany | 20 ml or 40 ml | 0.68 or 1.35 fl oz |
| Japan | 30 ml or 60 ml | 1.0 or 2.0 fl oz |
| Italy | 40 ml | 1.35 fl oz |
| France | 30 ml or 40 ml | 1.0 or 1.35 fl oz |
United States: 1 Shot Is Usually 1.5 Ounces
In the US, the standard shot is 1.5 US fluid ounces, which is about 44 ml. This is the size most American cocktail recipes assume when they say “1 shot” without more detail.
A US “double shot” is commonly 3 fl oz, or about 89 ml. If a recipe calls for 2 shots of whiskey, that usually means 3 fl oz total, not 2 fl oz.
Worked example: a drink with 1 shot vodka, 0.5 shot triple sec, and 0.5 shot lime juice equals 2 US shots total. That is 3 fl oz, or about 89 ml, before ice melt or shaking dilution.
UK, Ireland, And Metric Pours
In the UK, single spirits are commonly served as 25 ml or 35 ml measures. The exact size depends on the licensed premises, but the bar must be consistent for that drink category.
This makes UK recipes tricky. A “double” can mean 50 ml if the bar uses 25 ml singles, or 70 ml if it uses 35 ml singles. That is a 20 ml difference in one drink.
Ireland commonly uses 35.5 ml, close to 1.2 US fl oz. Two Irish shots equal about 71 ml, which sits between a UK 70 ml double and a US 3 fl oz double.
Why A Shot Glass May Not Equal One Shot
Many shot glasses hold more than the measured serving. A glass sold as a “2 oz shot glass” holds about 59 ml when filled to the rim, but a standard US shot poured into it is only 1.5 oz.
Edge case: a tall narrow shooter may look full at 1 oz, while a wide heavy-base glass may look underfilled at 1.5 oz. Shape changes the visual fill line, not the actual volume.
For recipe accuracy, measure in milliliters or US fluid ounces instead of relying on the glass. Use 44 ml for a US shot, 30 ml for many metric countries, and 25 ml or 35 ml for UK-style pours.
If converting a cocktail from US to UK measures, scale the whole drink. A US 1.5 oz pour is 44 ml. In a 25 ml UK bar, that is 1.76 singles; in a 35 ml bar, it is 1.26 singles.
For batching, the difference adds up fast. Ten US shots equal 15 fl oz, about 443 ml. Ten 30 ml shots equal 300 ml. Ten 25 ml shots equal 250 ml, nearly 44% less than ten US shots.
Single Versus Double Shots
A single shot in the U.S. is usually 1.5 fl oz, equal to 3 tablespoons, 44 ml, or 0.1875 cup. A double shot is usually 3 fl oz, equal to 6 tablespoons, 89 ml, or 0.375 cup.
Standard Pour Sizes
| Pour | Fluid ounces | Tablespoons | Milliliters | Cups |
|---|---|---|---|---|
| Half shot | 0.75 fl oz | 1.5 tbsp | 22 ml | 0.094 cup |
| Single shot | 1.5 fl oz | 3 tbsp | 44 ml | 0.1875 cup |
| Double shot | 3 fl oz | 6 tbsp | 89 ml | 0.375 cup |
| Triple shot | 4.5 fl oz | 9 tbsp | 133 ml | 0.5625 cup |
The catch: not every shot glass holds exactly 1.5 fl oz. Many small shot glasses are 1 fl oz, many standard bar glasses are 1.5 fl oz, and larger “double” shot glasses often hold 2 fl oz to 3 fl oz.
If a recipe says “1 shot” and gives no size, use 1.5 fl oz. If it says “2 shots,” use 3 fl oz. That keeps cocktails, desserts, marinades, and coffee drinks scaled to the common U.S. bar measure.
Worked Examples
Example 1: a drink calls for 2 shots of tequila. Using the U.S. default, 2 × 1.5 fl oz = 3 fl oz. That is 6 tablespoons or about 89 ml.
Example 2: a sauce calls for 1/2 shot of bourbon. Half of 1.5 fl oz is 0.75 fl oz. Measure 1 1/2 tablespoons, or about 22 ml.
Example 3: a batch cocktail calls for 8 single shots of vodka. 8 × 1.5 fl oz = 12 fl oz. That equals 1 1/2 cups, since 1 cup is 8 fl oz.
Example 4: you own a 2 fl oz shot glass. One filled glass is not a standard single; it is 1 1/3 standard shots. For one 1.5 fl oz shot, fill it to three-quarters.
Single vs Double in Real Glasses
A “single” shot glass may be marked 1 oz, 1.25 oz, or 1.5 oz. A “double” shot glass may be marked 2 oz or 3 oz. The label describes the glass, not always the recipe measure.
For accuracy, check the glass once with water. Fill it to the rim, pour into a liquid measuring cup, and note the amount. A rim-fill 2 oz glass should not be used as a 1.5 oz shot unless you underfill it.
For layered drinks, leave headroom. A 1.5 fl oz pour in a 1.5 fl oz glass reaches the rim and spills easily. A 2 fl oz glass holding a 1.5 fl oz single gives about 0.5 fl oz of working space.
For espresso, “single” and “double” do not match liquor shots. A single espresso is commonly about 1 fl oz, while a double is commonly about 2 fl oz. Do not substitute those sizes in cocktail recipes.
Bottom line: treat 1.5 fl oz as one standard U.S. shot and 3 fl oz as a double. If the glass has no marking, measure it; shot glasses vary enough to change a recipe by 25% to 100%.
How To Measure A Shot
A standard U.S. shot is usually 1.5 fl oz, equal to 3 tablespoons, 44 ml, or 9 teaspoons. A “short shot” may be 1 fl oz, and a large pour may be 2 fl oz.
For accuracy, measure the liquid itself, not the height of the glass. Shot glasses vary widely: many hold 1.5 oz to the rim, but some souvenir glasses hold 2 oz or more.
- 1. Pick the target size. Use 1.5 fl oz for a standard shot. Use 1 fl oz if the recipe says “pony shot.” Use 2 fl oz for a double only when the recipe or drink order calls for it.
- 2. Use a jigger if you have one. A common double-sided jigger measures 1.5 oz on the large side and 0.75 oz on the small side. Fill to the marked line or to the brim, depending on its design.
- 3. Use tablespoons if you do not have a jigger. Measure 3 level tablespoons for 1.5 oz. For 1 oz, use 2 tablespoons. For 2 oz, use 4 tablespoons.
- 4. Use teaspoons for small adjustments. One U.S. fluid ounce equals 6 teaspoons. A 1.5 oz shot equals 9 teaspoons. A half-shot of 0.75 oz equals 4 1/2 teaspoons.
- 5. Check an unknown shot glass with water. Fill the glass with water, then pour it into a liquid measuring cup. If it reaches 1.5 oz, it is a standard shot glass.
- 6. Mark the fill line. If the glass holds 2 oz to the rim, measure 1.5 oz of water into it and note the level. That is the standard-shot line, not the rim.
- 7. Measure sticky ingredients separately. For syrups, cream liqueurs, or honey mixers, use a jigger or measuring spoon. Thick liquids cling to glass and can under-pour if you eyeball them.
Shot Measurement Conversions
| Amount | Fluid ounces | Tablespoons | Teaspoons | Milliliters |
|---|---|---|---|---|
| Pony shot | 1 oz | 2 tbsp | 6 tsp | 30 ml |
| Standard shot | 1.5 oz | 3 tbsp | 9 tsp | 44 ml |
| Double shot | 2 oz | 4 tbsp | 12 tsp | 59 ml |
| Half shot | 0.75 oz | 1 1/2 tbsp | 4 1/2 tsp | 22 ml |
Worked Examples
If a cocktail needs 2 shots of vodka and you use the U.S. standard, measure 3 oz total. That is 6 tablespoons, 18 teaspoons, or about 89 ml.
If your shot glass holds 2 oz to the brim, filling it twice gives 4 oz, not 3 oz. For two standard shots, fill only to the 1.5 oz line twice.
If a recipe calls for 1/2 shot of lime juice, measure 0.75 oz. That equals 1 1/2 tablespoons, 4 1/2 teaspoons, or about 22 ml.
If you are scaling a drink for 4 servings and each serving uses 1 shot, measure 6 oz total liquor. That is 12 tablespoons or about 177 ml.
For neat pours, bars may use 1.25 oz, 1.5 oz, or 2 oz house standards. At home, choose one standard and measure it consistently so recipes stay balanced.
Shot Glass Size Chart
A standard U.S. shot is usually 1.5 fl oz, equal to 3 Tbsp, 44 mL, or 9 tsp. But actual shot glasses vary, so measuring once with water is the only reliable kitchen answer.
| Shot glass label | Fluid ounces | Tablespoons | Milliliters | Best use |
|---|---|---|---|---|
| Small shot | 1 fl oz | 2 Tbsp | 30 mL | Single small pour, espresso-style portions |
| Standard U.S. shot | 1.5 fl oz | 3 Tbsp | 44 mL | Most cocktail recipes and bar pours |
| Large shot | 2 fl oz | 4 Tbsp | 59 mL | Double-ish home pours, mixed drinks |
| Double shot glass | 3 fl oz | 6 Tbsp | 89 mL | Two standard shots |
| Mini tasting glass | 0.5 fl oz | 1 Tbsp | 15 mL | Samples, flavor extracts, syrups |
Quick Conversions For One Standard Shot
- 1 standard U.S. shot: 1.5 fl oz
- In tablespoons: 3 Tbsp
- In teaspoons: 9 tsp
- In milliliters: about 44 mL
- In cups: 3/16 cup, or 0.1875 cup
For recipe math, use 1 shot = 3 Tbsp. That is easier and more exact in a kitchen than eyeballing a line on a thick, tapered glass.
Example: if a sauce calls for 2 shots of bourbon, use 3 fl oz total. That equals 6 Tbsp, 18 tsp, or about 89 mL.
Example: if you only want half a shot of vanilla syrup, use 0.75 fl oz. That equals 1 1/2 Tbsp, 4 1/2 tsp, or about 22 mL.
Common Edge Cases
A “shot glass” filled to the rim may hold more than one shot. Many 1.5-fl-oz glasses have extra headspace and can physically hold 1.75 to 2 fl oz when brim-full.
A heavy-bottomed glass can look large but hold only 1 fl oz. The thick base adds height without adding volume, so visual size is not a dependable measure.
A tall narrow cordial glass may hold 1 oz, while a squat bar shot may hold 2 oz. Shape does not define capacity; liquid volume does.
If a glass has a fill line, measure to the line, not the rim. A 2-oz glass may have a 1.5-oz line for standard pours.
How To Check Your Shot Glass
Fill a tablespoon with water and pour it into the shot glass. Count level tablespoons until the liquid reaches the usual fill point.
| Tablespoons filled | Shot glass capacity |
|---|---|
| 1 Tbsp | 0.5 fl oz, 15 mL |
| 2 Tbsp | 1 fl oz, 30 mL |
| 3 Tbsp | 1.5 fl oz, 44 mL |
| 4 Tbsp | 2 fl oz, 59 mL |
| 6 Tbsp | 3 fl oz, 89 mL |
For cocktails, assume 1.5 fl oz only when the recipe says “1 shot” and gives no other measure. For baking, sauces, and syrups, convert the shot to tablespoons for repeatable results.
Rim Fill Versus Measured Pour
A shot glass can mean two different amounts: the liquid it holds when filled to the rim, and the liquor actually served in a measured pour. Those are not always the same number.
What “rim fill” means
Rim fill is the maximum capacity of the glass, filled level with the top edge. A small shot glass marked 1 oz holds 1 U.S. fl oz, or 29.57 ml, only if filled to that point.
A larger bar shot glass may rim-fill at 1.5 U.S. fl oz, which equals 44.36 ml. If it is filled slightly below the rim, the served amount is less than its stated full capacity.
What a measured pour means
A measured pour is the controlled serving amount. In the United States, a standard shot is commonly 1.5 U.S. fl oz, equal to 3 tablespoons or 44.36 ml.
Example: if a 2 oz shot glass is used for a 1.5 oz pour, the glass is only 75% full. That leaves 0.5 oz of headspace, or 14.79 ml.
Example: if a 1.5 oz shot glass is filled with only 1 oz, the pour is 66.7% of its rim capacity. The difference is 0.5 oz, the same as 1 tablespoon.
For recipes, use the measured pour, not the visual fill level. “1 shot” may mean 1.5 oz in many U.S. drink recipes, but a glass on your shelf may hold 1 oz, 1.5 oz, or 2 oz to the rim.
Shot Glass Versus Jigger
A shot glass is a small drinking glass; a jigger is a measuring tool. In U.S. recipes, “1 shot” usually means 1.5 fluid ounces, which equals 3 tablespoons or 44 milliliters.
A standard double-ended jigger commonly measures 1.5 fluid ounces on the large side and 0.75 fluid ounce on the small side. Some jiggers instead pair 2 ounces with 1 ounce.
Why the Difference Matters
Shot glasses are not always calibrated. A souvenir shot glass may hold 1 ounce, 1.25 ounces, 1.5 ounces, or 2 ounces when filled to the rim.
A jigger is made for repeatable pours. If a cocktail calls for 2 ounces of bourbon, use the 2-ounce side if you have one, or fill a 1.5-ounce jigger plus a 0.5-ounce measure.
Worked example: for a margarita with 1.5 ounces tequila, 1 ounce orange liqueur, and 0.75 ounce lime juice, one 1.5-ounce jigger pour equals the tequila amount exactly.
Then measure 1 ounce with a marked jigger or a 2-tablespoon measure. For 0.75 ounce lime juice, use the small side of a 1.5/0.75-ounce jigger, or 1.5 tablespoons.
If you only have a shot glass, test it with water first. Fill it, then pour into tablespoons: 3 tablespoons means 1.5 ounces; 2 tablespoons means 1 ounce.
Why Shot Glasses Vary
A “shot” is not one fixed volume. In the U.S., a standard bar shot is commonly 1.5 fl oz, which equals about 44 ml. But shot glasses sold for home use may hold 1 fl oz, 1.25 fl oz, 1.5 fl oz, or 2 fl oz.
Legal pours and local custom
Countries set different serving measures. The U.K. commonly uses 25 ml or 35 ml single measures. Australia commonly uses 30 ml. In the U.S., 1.5 fl oz is the usual reference, but bars may pour differently.
That means a recipe calling for “1 shot” can change a drink. If one person uses 30 ml and another uses 44 ml, the second pour is 14 ml larger, or about 47% more liquor.
Glass capacity is not the same as a measured pour
A shot glass may be filled to the rim, to a line, or short of the top. A 2 fl oz glass can still be used for a 1.5 fl oz pour, leaving 0.5 fl oz of headspace.
Worked example: if a cocktail calls for 2 shots of whiskey, using 1.5 fl oz shots gives 3 fl oz total. Using 1 fl oz glasses gives only 2 fl oz, a full 1 fl oz less.
Manufacturing also matters. Thick glass bases, flared sides, and decorative shapes change capacity. For accuracy, use a jigger marked in ounces or milliliters instead of assuming the glass size.

Common Questions
How much does a standard shot glass hold?
In the U.S., a standard shot is usually 1.5 fluid ounces, which equals 3 tablespoons or about 44 milliliters. Many bar shot glasses are sized to this amount, but decorative or souvenir shot glasses can vary, so measuring once is the most accurate check.
Is a shot glass 1 ounce or 1.5 ounces?
A shot glass can be either, but the common U.S. serving size is 1.5 fluid ounces. Smaller shot glasses often hold 1 ounce, especially for single pours or tastings. If a recipe says “1 shot” without more detail, use 1.5 ounces.
How many tablespoons are in a shot glass?
A 1.5-ounce shot glass holds 3 tablespoons. A 1-ounce shot glass holds 2 tablespoons. This conversion is useful for cocktails, sauces, extracts, and syrups when you do not have a jigger or liquid measuring cup nearby.
How many milliliters are in a shot?
A typical U.S. shot is about 44 milliliters, because 1.5 fluid ounces equals roughly 44 mL. A smaller 1-ounce shot is about 30 mL. For precise drink mixing, use the milliliter markings on a jigger.
How can I measure a shot without a shot glass?
Measure 1 shot as 3 tablespoons, 1.5 fluid ounces, or about 44 milliliters. If using measuring spoons, fill 1 tablespoon three times. If using a liquid measuring cup, pour to the 1.5-ounce mark if it has ounce markings.
What is the difference between a shot glass and a jigger?
A shot glass is usually the serving glass, while a jigger is a measuring tool used for pouring. In the U.S., a common jigger has 2 sides: 1.5 fluid ounces on the large side and 0.75 or 1 fluid ounce on the smaller side.
Should you fill a shot glass to the rim?
Not always. Many shot glasses hold more than a standard pour when filled to the rim. For accuracy, measure to the marked line if there is one, or use a jigger. A typical U.S. shot pour is 1.5 fluid ounces, not necessarily the glass’s full capacity.
