A standard U.S. shot glass holds 1.5 fluid ounces, which equals 3 tablespoons or about 44 milliliters. Some shot glasses hold 1 ounce or 2 ounces, so check the marking if exact measuring matters.
How Much Liquid Does A Shot Glass Hold: a standard U.S. shot glass holds 1.5 fluid ounces, equal to 3 tablespoons or about 44 milliliters. That is the pour most U.S. cocktail recipes mean when they call for “1 shot.”
Shot glasses are not all identical. Some small glasses hold 1 ounce, while larger double-shot glasses may hold 2 ounces or more. For accurate mixing, measure the glass with water once, or use a jigger marked in ounces or milliliters.
The Short Answer, With Numbers
A standard U.S. shot glass holds 1.5 fluid ounces, which equals 3 tablespoons, 9 teaspoons, or about 44 milliliters.
If a recipe says “1 shot” and gives no other detail, use 1.5 fl oz. That is the common U.S. bar pour for one shot of liquor.
| Measure | Amount in 1 U.S. Shot | Kitchen Equivalent |
|---|---|---|
| Fluid ounces | 1.5 fl oz | Standard U.S. shot |
| Tablespoons | 3 tbsp | Easy measuring-spoon substitute |
| Teaspoons | 9 tsp | Useful for small adjustments |
| Milliliters | About 44 ml | Metric recipe conversion |
| Half shot | 0.75 fl oz | 1.5 tbsp |
| Double shot | 3 fl oz | 6 tbsp |
Use 3 Tablespoons When You Do Not Have a Shot Glass
The fastest kitchen replacement is simple: 1 shot = 3 tablespoons. Fill a tablespoon three times, level or slightly rounded depending on the recipe’s tolerance.
For smaller pours, use teaspoons. Since 1 tablespoon equals 3 teaspoons, a full U.S. shot is 9 teaspoons. A half shot is 4.5 teaspoons.
Worked example: if a sauce calls for 2 shots of bourbon, use 3 fl oz, 6 tablespoons, or about 89 ml.
Worked example: if a dessert calls for 1/2 shot of rum, use 0.75 fl oz, 1 1/2 tablespoons, or about 22 ml.
Why Your Shot Glass May Not Match 1.5 Ounces
Many decorative shot glasses are not precise measuring tools. Some hold 1 fl oz, some hold 1.25 fl oz, and oversized novelty glasses may hold 2 fl oz or more.
The rim is another edge case. A glass filled to the very top may hold more than its intended pour line. For recipes, measure to a marked line if the glass has one.
If the recipe is boozy, a difference between 1 oz and 1.5 oz matters. Three “shots” could mean 3 oz with a small glass or 4.5 oz with a standard U.S. pour.
For consistent cooking and baking, treat the shot glass as a serving glass, not a measuring cup. Use tablespoons or a liquid measuring cup when the amount affects flavor, texture, or alcohol strength.
Bottom line: for U.S. recipes, count 1 shot as 1.5 fl oz. If accuracy matters, measure 3 tablespoons instead of trusting the glass.
Standard Shot Glass Volume
A standard U.S. shot glass holds 1.5 fluid ounces. That equals 3 tablespoons, 9 teaspoons, or about 44 milliliters.
For home measuring, treat one full standard shot as 1 1/2 fl oz. This is the amount most U.S. cocktail recipes mean when they say “1 shot.”
Quick Volume Conversions
| Shot amount | Fluid ounces | Tablespoons | Teaspoons | Milliliters |
|---|---|---|---|---|
| 1 standard shot | 1.5 fl oz | 3 Tbsp | 9 tsp | 44 mL |
| 1/2 shot | 0.75 fl oz | 1 1/2 Tbsp | 4 1/2 tsp | 22 mL |
| 2 shots | 3 fl oz | 6 Tbsp | 18 tsp | 89 mL |
| 3 shots | 4.5 fl oz | 9 Tbsp | 27 tsp | 133 mL |
If a recipe calls for 2 shots of vodka, measure 3 fl oz. That is 6 tablespoons, so you can use a tablespoon measure if you do not have a jigger.
If a sauce calls for 1/2 shot of bourbon, use 0.75 fl oz. In kitchen spoons, that is 1 tablespoon plus 1 1/2 teaspoons.
Why Some Shot Glasses Do Not Hold 1.5 Ounces
Not every glass labeled “shot glass” is actually 1.5 fl oz. Many souvenir glasses hold 2 fl oz, while smaller glasses may hold 1 fl oz.
A 1 fl oz shot glass equals 2 tablespoons. If you use it for a recipe expecting a standard shot, you will be short by 1 tablespoon.
A 2 fl oz shot glass equals 4 tablespoons. If you fill it for a recipe expecting one standard shot, you will add 1/2 fl oz too much.
That extra 1/2 fl oz matters in small recipes. In a 3-ounce cocktail, using a 2-ounce glass instead of 1.5 ounces increases that ingredient by about 33%.
How To Check Your Shot Glass
To verify capacity, fill the shot glass with water to the exact level you normally use. Pour it into a liquid measuring cup with ounce markings.
If your measuring cup is not precise enough, use spoons. A standard shot should take exactly 3 level tablespoons of water to fill to the same line.
If it fills at 2 tablespoons, it is a 1-ounce shot glass. If it fills at 4 tablespoons, it is a 2-ounce shot glass.
Filled To The Rim vs. Pour Line
Some shot glasses have a thick base, curved sides, or a printed line below the rim. The listed capacity may mean filled to the rim, not to the visible design line.
For recipes, use the level that gives the measured volume you need. If your glass holds 1.5 fl oz only when brim-full, pour carefully or use spoons for accuracy.
For batch drinks, scale by ounces, not by the number of glasses. For 8 standard shots, measure 12 fl oz, which is 1 1/2 cups.
US Versus Metric Shots
In the US, a standard shot is usually 1.5 US fluid ounces. In metric terms, that is 44.36 milliliters, commonly rounded to 44 ml or 45 ml.
That rounding matters. If a recipe says 1 shot and assumes 45 ml, using an exact 1.5 fl oz jigger gives 44.36 ml, a difference of only 0.64 ml. For home cooking or cocktails, that is negligible.
| Measure | US fluid ounces | Milliliters |
|---|---|---|
| US standard shot | 1.5 fl oz | 44.36 ml |
| Small US shot | 1 fl oz | 29.57 ml |
| Double US shot | 3 fl oz | 88.72 ml |
| Metric 25 ml shot | 0.85 fl oz | 25 ml |
| Metric 30 ml shot | 1.01 fl oz | 30 ml |
| Metric 50 ml shot | 1.69 fl oz | 50 ml |
What “One Shot” Means In US Recipes
For an American recipe, treat 1 shot as 1.5 fl oz unless the recipe gives another number. That equals 3 tablespoons, because 1 US tablespoon is 0.5 fl oz.
Worked example: a sauce calls for 2 shots of bourbon. In US terms, that is 3 fl oz total, or 6 tablespoons, or 88.72 ml. Rounding to 90 ml is practical.
Another example: a dessert recipe needs 1/2 shot of rum. Half of 1.5 fl oz is 0.75 fl oz. That equals 1 1/2 tablespoons, or about 22 ml.
Metric Shots Are Not One Fixed Size
Outside the US, “a shot” often means a metric pour, but the volume is not universal. Common metric sizes include 25 ml, 30 ml, and 50 ml.
A 25 ml shot is much smaller than a US shot. It is about 56% of a 44.36 ml US shot. If you use 25 ml for a US recipe, the liquid will be short by 19.36 ml per shot.
A 30 ml shot is close to 1 US fluid ounce, not 1.5. Three 30 ml shots equal 90 ml, which is close to two US shots at 88.72 ml.
A 50 ml metric shot is larger than a US shot by 5.64 ml. In a drink, that is a modest difference. In a baking recipe with strong alcohol or extract, it can noticeably change flavor.
Shot Glass Capacity Versus Measured Shot
A shot glass may hold more than the intended pour. Many glasses marked as “shot glasses” hold 2 fl oz to the rim, even though a US shot measure is 1.5 fl oz.
If you fill a 2 fl oz shot glass to the top, you are pouring 59.15 ml, not 44.36 ml. That is 33% more than a standard US shot.
For accuracy, use the line on a marked glass, a jigger, tablespoons, or a liquid measuring cup. Do not assume the rim equals one shot unless the glass is labeled 1.5 fl oz or 45 ml.
Quick conversion: 1 US shot = 1.5 fl oz = 3 tbsp = 44.36 ml. For most kitchen use, write it as 45 ml.
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. Some bars pour 1.25 fl oz or 2 fl oz, so measure the glass once instead of assuming.
Fast Measuring Method
- 1. Pick the shot size first. Use 1.5 fl oz for a standard U.S. shot. Use 1 fl oz for a small shot, 2 fl oz for a double-style pour, or the line marked on your jigger if a recipe specifies it.
- 2. Use a liquid measuring tool. Best choice: a jigger with 0.5, 0.75, 1, 1.5, and 2 fl oz marks. Second best: measuring spoons. One standard shot is exactly 3 tablespoons.
- 3. Fill to the meniscus. Set the jigger or measuring cup on a level counter. Pour until the bottom of the liquid curve sits on the mark. Do not measure while holding it in the air.
- 4. Convert if needed. For metric recipes, 1 U.S. shot of 1.5 fl oz is about 44 ml. A 1 fl oz pour is about 30 ml. A 2 fl oz pour is about 59 ml.
- 5. Check your shot glass capacity. Fill the shot glass with water, then pour that water into tablespoons or a jigger. If it holds 3 tablespoons, it is a 1.5 fl oz shot glass.
- 6. Mark the real fill line. If your glass holds 2 fl oz to the rim, a 1.5 fl oz shot will stop at 75% of its full capacity. Use a small piece of tape outside the glass as a guide.
Worked Examples
If a cocktail calls for 1 shot of whiskey and you are using a U.S. standard shot, pour 1.5 fl oz. That is 3 tablespoons or about 44 ml.
If a recipe calls for 2 shots of vodka, use 3 fl oz total. That equals 6 tablespoons, 18 teaspoons, or about 89 ml.
If your shot glass holds 2 fl oz to the rim, do not fill it to the top for a standard shot. Pour only 1.5 fl oz, leaving about one-quarter of the glass empty.
If you only have teaspoons, measure 9 level teaspoons for a 1.5 fl oz shot. For a 1 fl oz shot, measure 6 teaspoons. For a 2 fl oz pour, measure 12 teaspoons.
Common Shot Glass Edge Cases
| Container or Pour | Amount | How to Measure It |
|---|---|---|
| Standard U.S. shot | 1.5 fl oz | 3 tablespoons or 44 ml |
| Small shot | 1 fl oz | 2 tablespoons or 30 ml |
| Large shot | 2 fl oz | 4 tablespoons or 59 ml |
| Half shot | 0.75 fl oz | 1 1/2 tablespoons or 22 ml |
Thick liqueurs, syrups, and cream float higher on a spoon or jigger wall. Pause 1 second after pouring, then read the settled level at eye height.
For repeat drinks, measure the first pour exactly, then note where the liquid lands in your specific glass. Shot glasses vary, and the rim is not a reliable measuring line.
Common Shot Glass Sizes
A standard U.S. shot glass usually holds 1.5 fl oz, which equals 44 ml or 3 tablespoons. That is the size most drink recipes mean when they say “1 shot.”
Not every shot glass is 1.5 oz. Small bar glasses, tall shooters, and novelty glasses can differ by 0.5 oz or more, which changes a cocktail noticeably.
| Shot glass type | Typical capacity | Metric equivalent | Tablespoons |
|---|---|---|---|
| Small shot | 1 fl oz | 30 ml | 2 tbsp |
| Standard U.S. shot | 1.5 fl oz | 44 ml | 3 tbsp |
| Large shot | 2 fl oz | 59 ml | 4 tbsp |
| Double shot | 3 fl oz | 89 ml | 6 tbsp |
What “One Shot” Means in Recipes
For U.S. kitchen and cocktail measurements, treat 1 shot as 1.5 fl oz unless the recipe says otherwise. That is the cleanest conversion for cooking, batching drinks, and measuring spirits.
Worked example: if a sauce calls for 2 shots of bourbon, use 3 fl oz. That is 6 tablespoons, because each 1.5 oz shot equals 3 tablespoons.
Another example: a cocktail calling for 1 shot tequila, 1/2 shot lime juice, and 1/2 shot triple sec uses 1.5 oz tequila, 0.75 oz lime, and 0.75 oz triple sec.
Why Your Shot Glass May Not Match
A short, thick-bottomed glass may look like a full shot but hold only 1 oz. A taller shooter may hold 2 oz. Visual size is unreliable because glass thickness and shape vary.
The fill line matters too. Some glasses hold 1.5 oz only when filled to the brim. If you stop below the rim to avoid spilling, the pour may be closer to 1.25 oz.
Edge case: a “2 oz shot glass” used half full is not a standard shot unless the fill is exactly 1.5 oz. Half of a 2 oz glass is only 1 oz, which is one-third less than a U.S. shot.
Another edge case: a 30 ml shot glass is common outside the U.S. That is about 1 fl oz, not 1.5 fl oz. Using it as a U.S. shot shortchanges a recipe by about 14 ml.
Fast Measuring Conversions
- 1 U.S. shot = 1.5 fl oz = 44 ml = 3 tablespoons
- 1/2 shot = 0.75 fl oz = 22 ml = 1 1/2 tablespoons
- 2 shots = 3 fl oz = 89 ml = 6 tablespoons
- 4 shots = 6 fl oz = 177 ml = 3/4 cup
For accuracy, fill your shot glass with water and pour it into a liquid measuring cup. If it reaches 1.5 oz, it is a standard U.S. shot glass. If not, label it mentally as 1 oz, 2 oz, or whatever it actually holds.
Quick Pouring Reference
A standard U.S. shot is 1.5 fl oz, which equals 3 tablespoons, 9 teaspoons, or about 44 ml. Use this as the default unless a recipe or bottle label says otherwise.
| Pour | Fluid ounces | Tablespoons | Teaspoons | Milliliters |
|---|---|---|---|---|
| Half shot | 0.75 fl oz | 1.5 tbsp | 4.5 tsp | 22 ml |
| Standard shot | 1.5 fl oz | 3 tbsp | 9 tsp | 44 ml |
| Double shot | 3 fl oz | 6 tbsp | 18 tsp | 89 ml |
| Jigger large side | 1.5 fl oz | 3 tbsp | 9 tsp | 44 ml |
| Jigger small side | 0.75 fl oz | 1.5 tbsp | 4.5 tsp | 22 ml |
Fast Kitchen Conversions
If a sauce, glaze, or dessert calls for 1 shot of liquid, measure 3 level tablespoons. This works for liquor, espresso, lemon juice, syrup, vanilla mixture, or any other pourable liquid.
For 2 shots, use 6 tablespoons, or 3 fl oz. For 4 shots, use 12 tablespoons, which is 3/4 cup. For 8 shots, use 1 1/2 cups.
A 1-cup measure holds 8 fl oz. That is 5 1/3 standard shots. If you need exactly 1 cup from shots, pour 5 shots plus 1 tablespoon.
A half cup is 4 fl oz. That equals 2 standard shots plus 2 tablespoons. Do not use 3 shots; that gives 4.5 fl oz and overmeasures by 1 tablespoon.
Worked Examples
If a recipe says “add 2 shots of bourbon,” use 3 fl oz. In spoon measures, that is 6 tablespoons. In metric, it is about 89 ml.
If you are scaling a cocktail-style sauce from 1 shot to 3 shots, multiply 1.5 fl oz by 3. The total is 4.5 fl oz, equal to 9 tablespoons.
If you only have teaspoons, 1 shot is 9 teaspoons. A half shot is 4 1/2 teaspoons. A double shot is 18 teaspoons.
Edge Cases: Shot Glasses Vary
Not every shot glass is 1.5 fl oz. Some small glasses hold 1 fl oz; some tall novelty glasses hold 2 fl oz or more. For recipes, measure the glass once with water.
To check your glass, fill it to the normal pour line, then pour that water into measuring spoons. If it fills 3 tablespoons, it is a standard 1.5 fl oz shot glass.
If it fills only 2 tablespoons, it holds 1 fl oz. If it fills 4 tablespoons, it holds 2 fl oz. Mark that glass mentally as nonstandard for cooking.
For sticky liquids like honey, syrup, or liqueur, a shot glass may leave residue on the sides. For accuracy, measure with tablespoons or rinse the shot glass with a little recipe liquid.
For espresso, many U.S. coffee recipes treat a single shot as about 1 fl oz, not 1.5 fl oz. If the recipe is coffee-specific, follow its stated ounce amount rather than the bar shot size.
Frequently Asked Questions
How much liquid 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 shot glasses physically hold more than 1.5 ounces if filled to the rim, so use a liquid measuring cup for exact recipes.
Is a shot glass 1 ounce or 1.5 ounces?
Most U.S. recipes and bars treat 1 shot as 1.5 fluid ounces. Some small shot glasses hold 1 ounce, and some countries use different sizes. If a recipe says “1 shot” without details, 1.5 fluid ounces is the safest U.S. assumption.
How many tablespoons are in a shot glass?
A U.S. 1.5-ounce shot equals 3 tablespoons. A 1-ounce shot equals 2 tablespoons. For cooking, check the actual capacity of your glass, because decorative or oversized shot glasses may not match the standard bar measure.
How many milliliters are in a shot?
A U.S. standard shot is about 44 milliliters. If you are converting a recipe, 1.5 fluid ounces equals 44.36 milliliters. A smaller 1-ounce shot is about 30 milliliters, so the difference matters in drinks and sauces.
Can I use a shot glass for measuring ingredients?
Yes, if you know its capacity. Fill it with water, then pour into a measuring cup to confirm the amount. Many shot glasses are 1, 1.5, or 2 fluid ounces. For baking or precise cocktails, use a marked measuring tool.
