A standard shot glass in the U.S. holds 1.5 fluid ounces, equal to 3 tablespoons or about 44 milliliters. Some bars use 1-ounce or 2-ounce pours, but 1.5 fl oz is the common standard.
How Much Is A Standard Shot Glass: in the U.S., a standard shot glass holds 1.5 fluid ounces, equal to 3 tablespoons or about 44 milliliters.
Bar shot glasses can vary, so do not assume every small glass is 1.5 ounces. Some hold 1 ounce, 2 ounces, or more when filled to the rim. For accurate cocktail measurements, use a marked jigger or measure water into the glass once to confirm its true capacity.
The Short Answer, With Numbers
A standard shot glass in the United States is 1.5 fluid ounces, which is about 44 milliliters or 3 tablespoons.
If a recipe says “1 shot” and does not specify a size, use 1.5 fl oz. That is the default bar pour for a standard American shot.
| Measure | Amount | Best Use |
|---|---|---|
| Standard U.S. shot | 1.5 fl oz | Default for cocktails and recipes |
| Standard U.S. shot | 44 ml | Metric equivalent |
| Standard U.S. shot | 3 tbsp | Kitchen measuring spoon equivalent |
| Small shot glass | 1 fl oz | Common in novelty or tasting glasses |
| Double shot | 3 fl oz | Two standard U.S. shots |
What To Use If You Do Not Have A Shot Glass
Use 3 tablespoons for one standard shot. Since 1 tablespoon equals 0.5 fl oz, three tablespoons give you exactly 1.5 fl oz.
For a half shot, measure 1.5 tablespoons. For a double shot, measure 6 tablespoons, which equals 3 fl oz.
If using a liquid measuring cup, pour to 1.5 fl oz if marked. If the cup only shows ounces in whole numbers, measure 3 tablespoons instead for better accuracy.
Worked Examples
If a margarita recipe calls for 2 shots of tequila, use 3 fl oz. In tablespoons, that is 6 tbsp.
If an espresso martini calls for 1 shot of vodka and 1/2 shot of coffee liqueur, use 1.5 fl oz vodka and 0.75 fl oz liqueur.
If a punch recipe calls for 8 shots of rum, multiply 8 by 1.5. You need 12 fl oz of rum, which is 1.5 cups.
Important Edge Cases
Not every physical shot glass holds exactly 1.5 fl oz. Some hold 1 fl oz, some hold 2 fl oz, and oversized souvenir glasses may hold more.
The fill line matters. A 2 fl oz shot glass filled halfway is only 1 fl oz. A 1.5 fl oz shot glass filled to the rim is one standard shot.
For baking, sauces, or batched drinks, do not rely on the glass shape. Measure the liquid as 1.5 fl oz, 44 ml, or 3 tbsp per shot.
Standard Shot Glass Size
A standard shot glass in the United States holds 1.5 fluid ounces. That equals 3 tablespoons, 9 teaspoons, or about 44 milliliters.
For recipes, use 1 shot = 1.5 fl oz unless the recipe says otherwise. This is the most useful number for cocktails, dessert sauces, marinades, and measuring small amounts of liquid.
| Measure | Equivalent |
|---|---|
| 1 standard U.S. shot | 1.5 fl oz |
| 1 standard U.S. shot | 3 tbsp |
| 1 standard U.S. shot | 9 tsp |
| 1 standard U.S. shot | About 44 ml |
| 2 standard shots | 3 fl oz |
Why Some Shot Glasses Do Not Measure 1.5 Ounces
Many shot glasses look standard but are not exact measuring tools. Common home shot glasses may hold 1 ounce, 1.25 ounces, 1.5 ounces, or 2 ounces when filled to the rim.
The usable pour line may also differ from the rim capacity. A glass that holds 2 ounces to the top may be intended for a 1.5-ounce pour with space left above the liquid.
If accuracy matters, check the glass with measuring spoons. Fill it with 3 tablespoons of water. If that reaches the intended fill line, the glass measures a standard 1.5-ounce shot.
Shot Glass Size for Cooking and Baking
In a kitchen recipe, a shot is best treated as 1.5 fl oz. For example, if a sauce calls for 2 shots of bourbon, use 3 fl oz, which is 6 tablespoons.
If a dessert calls for half a shot of espresso liqueur, measure 0.75 fl oz. That equals 1 1/2 tablespoons, or 4 1/2 teaspoons.
If a marinade calls for 4 shots of tequila, use 6 fl oz. That is 3/4 cup, because 1 cup is 8 fl oz.
| Number of shots | Fluid ounces | Tablespoons | Cups |
|---|---|---|---|
| 1/2 shot | 0.75 fl oz | 1 1/2 tbsp | 3/32 cup |
| 1 shot | 1.5 fl oz | 3 tbsp | 3/16 cup |
| 2 shots | 3 fl oz | 6 tbsp | 3/8 cup |
| 4 shots | 6 fl oz | 12 tbsp | 3/4 cup |
Single Shot, Double Shot, and Jigger Sizes
A single shot usually means 1.5 fl oz in U.S. recipes. A double shot usually means 3 fl oz. That is simply two standard shots.
A bar jigger often has two sides. A common jigger measures 1.5 fl oz on the large side and 0.75 fl oz on the small side.
Some jiggers use 1 fl oz and 2 fl oz sides instead. Read the markings before measuring, especially when making scaled cocktails or concentrated sauces.
Edge Cases: Mini, Tall, and Souvenir Shot Glasses
Mini shot glasses may hold only 1 fl oz. If you use one as a recipe shot, the recipe will be short by 0.5 fl oz, or 1 tablespoon.
A 2-ounce shot glass filled to the rim gives 33% more liquid than a 1.5-ounce standard shot. In a 4-shot recipe, that adds 2 extra ounces.
Souvenir glasses are especially unreliable. Treat them as drinkware, not measuring tools, unless you have checked their capacity with tablespoons or a liquid measuring cup.
US Shot Versus Other Countries
In the United States, a “standard shot” is usually 1.5 US fluid ounces, which equals 44.36 ml. In recipes and bar measurements, rounding it to 45 ml is normal.
The catch: “shot glass” is not a single worldwide size. A glass that looks like one shot in another country may pour 25 ml, 30 ml, 40 ml, 50 ml, or 60 ml.
Common Shot Sizes by Country
| Country | Common shot size | US fluid ounces |
|---|---|---|
| United States | 44 ml / 1.5 US fl oz | 1.5 |
| United Kingdom | 25 ml or 35 ml | 0.85 or 1.18 |
| Canada | 43 ml / 1.5 Canadian fl oz | about 1.45 |
| Australia | 30 ml | 1.01 |
| Germany | 20 ml or 40 ml | 0.68 or 1.35 |
| Japan | 30 ml or 60 ml | 1.01 or 2.03 |
A US 1.5 oz shot is nearly twice a UK 25 ml single. If a cocktail calls for 2 US shots of whiskey, that is about 89 ml. Using 2 UK 25 ml shots gives only 50 ml.
That difference changes the drink. In a whiskey sour, 89 ml whiskey plus lemon and syrup tastes much stronger than 50 ml whiskey with the same mixers.
Worked Conversion Examples
Example 1: A US recipe calls for 1 shot vodka. Use 45 ml. If your jigger is 30 ml, pour 1 full 30 ml measure plus half again, about 15 ml.
Example 2: A UK recipe calls for 2 x 25 ml gin. That is 50 ml. In US terms, it is about 1.7 US fl oz, slightly more than one standard US shot.
Example 3: A Japanese 60 ml pour equals about 2 US fl oz. That is not one US bar shot; it is closer to a large double.
Example 4: A German 20 ml schnapps pour is under half of a US 1.5 oz shot. Two German 20 ml pours make 40 ml, still short of a US 44 ml shot.
Edge Cases That Cause Confusion
A souvenir shot glass may hold 2 oz, 3 oz, or more when filled to the rim. That does not mean the intended serving is that large. Many are decorative, not calibrated.
“One shot” in a home bar can mean a full glass, a jigger side, or a recipe unit. For accuracy, ignore the glass shape and measure by milliliters or US fluid ounces.
If a bottle label or recipe says 1 oz, do not treat it as a standard US shot. One US fluid ounce is 29.57 ml, about two-thirds of a 1.5 oz shot.
For US cocktail recipes, use this rule: 1 shot = 1.5 US fl oz = 44.36 ml. For international recipes, check whether “shot” means 25 ml, 30 ml, 35 ml, 40 ml, 50 ml, or 60 ml.
Shot Glass Measurement Chart
A standard shot glass in the U.S. is usually 1.5 fluid ounces, equal to 44.36 mL or 3 tablespoons. Many bars use this as the default “one shot” pour for liquor, whiskey, vodka, rum, tequila, and liqueurs.
| Shot size | Fluid ounces | Milliliters | Tablespoons | Common use |
|---|---|---|---|---|
| Pony shot | 1 fl oz | 29.57 mL | 2 tbsp | Small pour, tasting, lower-alcohol cocktails |
| Standard U.S. shot | 1.5 fl oz | 44.36 mL | 3 tbsp | Most American drink recipes |
| Large shot | 2 fl oz | 59.15 mL | 4 tbsp | Generous pour or double in some bars |
| Double shot | 3 fl oz | 88.72 mL | 6 tbsp | Two standard U.S. shots |
Quick Conversions For A Standard Shot
One standard 1.5-ounce shot equals 44.36 mL, 3 tablespoons, 9 teaspoons, or 0.1875 cup. If a recipe says “1 shot” without details, use 1.5 fl oz for U.S. cocktail measurements.
For a half shot, measure 0.75 fl oz. That equals 22.18 mL, 1.5 tablespoons, or 4.5 teaspoons. This is useful for strong ingredients such as absinthe, bitters-heavy liqueurs, or overproof rum.
For a double shot, use 3 fl oz. That equals 88.72 mL, 6 tablespoons, or 18 teaspoons. In U.S. home mixing, a double is normally exactly two 1.5-ounce pours.
Worked Examples
If a margarita calls for 2 shots of tequila, measure 3 fl oz total. That is 88.72 mL, or 6 tablespoons. Add the tequila first if your jigger has a 1.5-ounce side.
If a recipe needs 1 shot vodka and 0.5 shot coffee liqueur, use 1.5 fl oz vodka and 0.75 fl oz liqueur. Total alcohol volume before mixers is 2.25 fl oz, or 66.54 mL.
If you only have tablespoons, a standard shot is easy: 3 level tablespoons. A pony shot is 2 tablespoons. A double is 6 tablespoons. Use level fills, not heaping spoonfuls.
Edge Cases: Why Shot Glasses Differ
Not every shot glass holds exactly 1.5 fl oz. Some decorative glasses hold 1 fl oz, while tall “shooter” glasses may hold 2 fl oz or more when filled to the rim.
Rim capacity is not always the intended pour line. A glass that holds 2 fl oz to the brim may be designed for a 1.5-ounce pour with headspace to prevent spilling.
To check your glass, fill it with water and pour into measuring spoons. If it takes 3 tablespoons, it is a standard 1.5-ounce shot. If it takes 4 tablespoons, it holds 2 fl oz.
For bottle math, a 750 mL bottle contains about 16 standard U.S. shots. Divide 750 by 44.36 mL: the result is 16.9, but spills and slightly heavy pours make 16 realistic.
For exact recipes, measure with a jigger instead of relying on the glass. A common jigger has 1.5 fl oz on one side and 0.75 fl oz on the other, matching a standard shot and half shot.
How To Measure A Shot
A standard U.S. shot is usually 1.5 fl oz, which equals 3 tablespoons, 44 ml, or 9 teaspoons. Use that as your default unless a recipe, bar, or jigger marking says otherwise.
Fast Measuring Method
- 1. Pick your target size. For most U.S. drink recipes, measure 1 shot as 1.5 fl oz. A smaller “short shot” is often 1 fl oz, and a double is commonly 3 fl oz.
- 2. Use the best tool available. A jigger is fastest. The common two-sided jigger is 1.5 fl oz on the large side and 0.75 fl oz on the small side. Read the stamped marking if it has one.
- 3. Fill to the rim or marked line. If the jigger has no line, fill it level to the top without a dome. If it has a line below the rim, stop at the line, not the rim.
- 4. Convert if using spoons. For 1 standard shot, measure 3 level tablespoons. For 0.5 shot, use 1.5 tablespoons. For 2 shots, use 6 tablespoons.
- 5. Convert if using a liquid measuring cup. Pour to 1.5 fl oz, 3 tablespoons, or about 44 ml. Use the cup on a flat counter and read the line at eye level.
- 6. Check odd shot glasses. Many decorative shot glasses hold more than 1.5 fl oz. Test yours once with water: pour in 3 tablespoons. If it does not reach the rim, the glass is oversized.
- 7. Scale the drink before pouring. For 4 cocktails needing 1.5 fl oz each, measure 6 fl oz total liquor. That equals 12 tablespoons, 177 ml, or four standard shots.
Shot Size Conversions
| Amount | Fluid ounces | Tablespoons | Milliliters |
|---|---|---|---|
| Half shot | 0.75 fl oz | 1.5 tbsp | 22 ml |
| Standard U.S. shot | 1.5 fl oz | 3 tbsp | 44 ml |
| Double shot | 3 fl oz | 6 tbsp | 89 ml |
Worked example: A margarita calls for 2 shots of tequila. Using the U.S. standard, that is 3 fl oz total. Measure 6 tablespoons, or fill a 1.5 fl oz jigger twice.
Edge case: If your shot glass holds 2 fl oz to the rim, a full pour is not a standard shot. Stop at three-quarters full to pour about 1.5 fl oz.
Another edge case: Some recipes use “1 part” instead of “1 shot.” If 1 part equals 1.5 fl oz, then 2 parts equal 3 fl oz and 0.5 part equals 0.75 fl oz.
For accuracy, do not count “one Mississippi” free-pours unless you have calibrated the pour spout. Pouring speed varies too much between bottles, spouts, and liquid levels.
Common Pouring Mistakes
The standard U.S. shot is 1.5 fl oz, which equals 3 tablespoons, 44 mL, or about 9 teaspoons. The most common mistake is treating every small glass as a true 1.5-ounce measure.
Using the Glass as the Measuring Tool
Many “shot glasses” hold more than 1.5 fl oz when filled to the rim. A thick-bottomed souvenir glass may look standard but hold 2 fl oz, 2.25 fl oz, or even 3 fl oz.
If a recipe calls for 2 shots of tequila, it usually means 3 fl oz total. If your glass actually holds 2 fl oz, filling it twice gives 4 fl oz, a 33% overpour.
Edge case: a narrow, tall glass may look larger than a squat glass but hold less. Shape is unreliable. Measure once with water: 1.5 fl oz equals 3 level tablespoons.
Filling to the Rim Instead of the Line
Some shot glasses have a visible line below the rim. That line may mark 1 fl oz, 1.25 fl oz, or 1.5 fl oz. The rim can be a “presentation space,” not the measured amount.
Worked example: a glass has a 1.5 fl oz line but holds 2 fl oz to the rim. Filling 6 drinks to the rim adds 3 extra fl oz total, equal to 2 additional standard shots.
This matters in batch cocktails. For 8 margaritas needing 12 fl oz tequila, a 2-ounce pour used 8 times gives 16 fl oz. That is 4 fl oz extra, or 2.67 standard shots.
Confusing Jiggers, Shots, and Ounces
A common double jigger is 1.5 fl oz on one side and 0.75 fl oz on the other. Another style is 2 fl oz and 1 fl oz. Do not assume the larger side is always one shot.
If a recipe says “1 shot,” use 1.5 fl oz unless the recipe defines it differently. If it says “1 oz,” that is two-thirds of a standard shot, not a full shot.
Quick conversions: 0.5 fl oz is 1 tablespoon. 1 fl oz is 2 tablespoons. 1.5 fl oz is 3 tablespoons. 2 fl oz is 4 tablespoons.
Counting Seconds Instead of Measuring
A free pour is not a fixed unit. Pour speed changes with bottle neck, spout, bottle angle, liquid thickness, and how full the bottle is.
If your pour spout delivers 0.5 fl oz per second, a 3-second count gives 1.5 fl oz. If it delivers 0.6 fl oz per second, the same count gives 1.8 fl oz.
That 0.3 fl oz error seems small, but across 10 drinks it becomes 3 fl oz, equal to 2 standard shots. For consistent recipes, measure instead of counting.
Scaling Recipes Without Doing the Math
For a 750 mL bottle, use 44 mL per standard shot. That bottle contains about 17 standard 1.5-ounce shots, not 25 full-size U.S. shots.
A 1-liter bottle contains about 22 standard shots. If you plan 12 drinks at 2 shots each, you need 24 shots, or about 1,056 mL. One liter is short.
For kitchen measuring, the cleanest substitute is 3 tablespoons per standard shot. For half a shot, use 1.5 tablespoons. For a double shot, use 6 tablespoons.
Frequently Asked Questions
How much is a standard shot glass in the US?
A standard US shot glass holds 1.5 fluid ounces, which equals 3 tablespoons, 9 teaspoons, or about 44 milliliters. Many bar recipes use 1 shot to mean 1.5 ounces, but some small shot glasses hold only 1 ounce.
Is a shot glass 1 ounce or 1.5 ounces?
In the US, a standard shot is 1.5 ounces. However, many shot glasses sold for home use are 1 ounce, 1.25 ounces, 1.5 ounces, or 2 ounces. If accuracy matters for cocktails, measure the glass with water and a tablespoon.
How many tablespoons are in a standard shot?
A standard 1.5-ounce shot equals 3 US tablespoons. Since 1 tablespoon equals 0.5 fluid ounce, you can measure a shot without a shot glass by using 3 level tablespoons of liquid.
How many milliliters are in a shot glass?
A standard US shot is about 44 milliliters. Rounded cocktail measurements often list it as 45 milliliters. A 1-ounce shot glass holds about 30 milliliters, so check the glass size before assuming it is standard.
What size shot glass should I use for cocktail recipes?
Use a 1.5-ounce shot glass for most US cocktail recipes unless the recipe states another amount. For better precision, use a jigger marked 0.5, 1, and 1.5 ounces, because decorative shot glasses often vary in capacity.
