A standard shot glass in the U.S. holds 1.5 fluid ounces, equal to 3 tablespoons or about 45 ml. Note that some small “shot” glasses hold only 1 fluid ounce, or 2 tablespoons.
How Many Ounces In A Standard Shot Glass: a standard US shot glass holds 1.5 fluid ounces, equal to 3 tablespoons or about 45 ml.
Shot glasses are often sold in slightly different sizes, so check the marking if precision matters. For recipes, measure 1.5 fl oz as 3 tbsp; if using the reference table, 1 fl oz = 2 tbsp = 30 ml, so a standard shot is about 45 ml.
The Short Answer, With Numbers
A standard U.S. shot is usually 1.5 fluid ounces. Using the reference conversions, that equals 3 tablespoons or about 45 ml.
The math is direct: 1 fluid ounce equals 2 tablespoons and 30 ml. A 1.5-ounce shot is 1 fluid ounce plus 1 tablespoon, so it is 30 ml plus 15 ml.
| Measure | US Equivalent | Metric | Shot-Glass Use |
|---|---|---|---|
| 1 teaspoon | – | 5 ml | Useful for small overflow or under-pour checks |
| 1 tablespoon | 3 teaspoons | 15 ml | Half of 1 fluid ounce |
| 1 fluid ounce | 2 tablespoons | 30 ml | A smaller shot or 2/3 of a 1.5-ounce shot |
| 1/4 cup | 4 tablespoons | 59 ml | Equals 2 fluid ounces, larger than a standard shot |
| 1/2 cup | 8 tablespoons | 118 ml | Equals four 1-fluid-ounce pours |
| 1 cup | 16 tbsp / 8 fl oz | 237 ml | Equals eight 1-fluid-ounce pours |
Standard Shot Math
For a 1.5-fluid-ounce shot: start with 1 fluid ounce, which is 2 tablespoons. Add 1 more tablespoon. Total: 3 tablespoons.
For metric measuring, use 1 fluid ounce as 30 ml and 1 tablespoon as 15 ml. Total: 30 ml + 15 ml = 45 ml.
If your shot glass holds exactly 1 fluid ounce, it holds 2 tablespoons or 30 ml. That is smaller than the common 1.5-ounce U.S. pour.
If your shot glass holds 2 fluid ounces, it equals 1/4 cup, because 1/4 cup is 4 tablespoons and 1 fluid ounce is 2 tablespoons.
So a 2-ounce shot glass holds 4 tablespoons or 59 ml. It is larger than a 1.5-ounce shot by 1 tablespoon.
Worked Examples
Example 1: A recipe calls for 1 shot of liquid. If it means a standard U.S. shot, measure 3 tablespoons.
Example 2: A cocktail needs 2 standard shots. Measure 6 tablespoons, which is 3 fluid ounces or about 90 ml.
Example 3: You have only a 1-tablespoon spoon. Fill it 3 times for one standard 1.5-ounce shot.
Example 4: You have a 1/4-cup measure. A full 1/4 cup is 2 fluid ounces, so use only 3 of its 4 tablespoons for a standard shot.
The key difference is between the glass capacity and the pour size. A shot glass may physically hold 1, 1.5, or 2 fluid ounces, but the common U.S. shot pour is 1.5 fluid ounces.
Standard Shot Glass Ounces
A standard shot glass in the United States is generally 1.5 fluid ounces. That equals 3 tablespoons, because 1 fluid ounce equals 2 tablespoons.
In metric terms, a 1.5-ounce shot is about 45 ml, using 1 fluid ounce as 30 ml. So the quick conversion is: 1 standard shot = 1.5 fl oz = 3 tbsp = 45 ml.
Standard U.S. Shot Size
| Shot amount | Tablespoons | Metric |
|---|---|---|
| 1 fl oz | 2 tbsp | 30 ml |
| 1.5 fl oz | 3 tbsp | 45 ml |
| 2 fl oz | 4 tbsp | 59 ml |
The most common “standard shot” for cocktails is 1.5 fl oz. A 2 fl oz pour is often called a double only in some bars, while others treat 3 fl oz as a true double.
Do not assume every shot glass holds exactly 1.5 fl oz. Many small glasses look like a shot glass but may hold 1 fl oz, 1.25 fl oz, 1.5 fl oz, or 2 fl oz when filled to the rim.
Worked Examples
If a recipe calls for 1 shot of liquor, use 1.5 fl oz unless the recipe says otherwise. Measured with spoons, that is 3 tablespoons.
If a cocktail needs 2 shots, multiply 1.5 fl oz by 2. The total is 3 fl oz, which equals 6 tablespoons.
If a punch recipe calls for 4 shots, use 6 fl oz total. Since 1 cup equals 8 fl oz, 4 standard shots equal 3/4 cup.
If you only have a tablespoon, measure 3 tablespoons for one standard U.S. shot. For a half-shot, measure 1.5 tablespoons.
Edge Cases When Measuring
A “pony shot” is commonly smaller than a standard shot. If your glass is marked at 1 fl oz, that is 2 tablespoons, not a full 1.5-ounce cocktail shot.
A tall, heavy-bottomed shot glass may look larger than it measures. Thick glass can make a 1.5 fl oz glass appear similar to a 2 fl oz glass.
Some novelty shot glasses hold 2 fl oz or more when filled to the rim. For recipes, measure to the intended line, not the rim, unless the recipe specifies a full glass.
For accurate cocktails, use a jigger with markings. A common setup is a larger 1.5 fl oz side and a smaller 1 fl oz side, giving you both 45 ml and 30 ml measures.
Fast answer: a standard U.S. shot glass holds 1.5 fluid ounces, which is 3 tablespoons or about 45 ml.
US Shot Versus Other Countries
In the United States, a standard shot is usually 1.5 fluid ounces. Using kitchen measures, that equals 3 tablespoons, because 1 fluid ounce equals 2 tablespoons.
Metric-wise, 1.5 US fluid ounces is about 45 ml. Since 1 fluid ounce is 30 ml, the math is 1.5 × 30 ml = 45 ml.
A 1-ounce shot glass is smaller: 2 tablespoons, or 30 ml. A 2-ounce shot glass is larger: 4 tablespoons, or 1/4 cup, which is 59 ml.
Common Shot Sizes By Country
| Place | Common shot size | US fl oz equivalent | Tablespoon equivalent |
|---|---|---|---|
| United States | 1.5 fl oz | 1.5 fl oz | 3 tbsp |
| United Kingdom | 25 ml or 35 ml | About 0.8 or 1.2 fl oz | About 1.7 or 2.3 tbsp |
| Canada | 1.5 fl oz is common | 1.5 fl oz | 3 tbsp |
| Australia | 30 ml | 1 fl oz | 2 tbsp |
| Japan | 30 ml is common | 1 fl oz | 2 tbsp |
| Germany | 20 ml or 40 ml | About 0.7 or 1.3 fl oz | About 1.3 or 2.7 tbsp |
The key difference is that the US bar “standard” is larger than many international pours. A US 1.5-ounce shot is 50% larger than a 1-ounce, 30 ml pour.
Worked example: if a cocktail recipe calls for 2 US shots, that means 3 fluid ounces total. In tablespoons, 2 × 3 tablespoons = 6 tablespoons.
In metric, 2 US shots equal about 90 ml. The same recipe made with two 30 ml shots would use only 60 ml, short by 30 ml, or 1 fluid ounce.
That difference changes recipes fast. Four US shots equal 6 fluid ounces, or 12 tablespoons. Four 30 ml shots equal 120 ml, about 4 fluid ounces, or 8 tablespoons.
Edge Cases: What Your Shot Glass May Actually Hold
Not every “shot glass” holds one standard shot. Many souvenir or tasting glasses hold 1 fluid ounce. Some double-shot glasses hold 2 fluid ounces.
If a glass reaches the brim at 2 fluid ounces, filling it halfway is not automatically 1.5 ounces. Half of 2 fluid ounces is 1 fluid ounce, or 2 tablespoons.
For a 1.5-ounce pour in a 2-ounce glass, fill it to three-quarters. The math is 1.5 ÷ 2 = 0.75, so the fill level is 75% of the glass.
If you do not know the glass size, measure with tablespoons. A US standard shot is 3 tablespoons. A small 1-ounce shot is 2 tablespoons. A double 2-ounce shot is 4 tablespoons.
For recipe accuracy, use volume, not the glass name. “One shot” can mean 25 ml, 30 ml, 35 ml, 40 ml, 1 fluid ounce, 1.5 fluid ounces, or 2 fluid ounces depending on place and glass.
Single Shot And Double Shot
A standard single shot in the U.S. is usually 1.5 fluid ounces. Using kitchen measures, that equals 3 tablespoons, because 1 fluid ounce equals 2 tablespoons.
In metric terms, a 1.5-ounce single shot is about 45 ml, using the standard kitchen conversion of 1 fluid ounce to 30 ml.
A standard double shot is simply twice that amount: 3 fluid ounces. That equals 6 tablespoons, or about 90 ml.
Single vs. Double Shot Measures
| Pour | Fluid ounces | Tablespoons | Milliliters |
|---|---|---|---|
| Single shot | 1.5 fl oz | 3 tbsp | 45 ml |
| Double shot | 3 fl oz | 6 tbsp | 90 ml |
| Half shot | 0.75 fl oz | 1.5 tbsp | 22.5 ml |
| Two single shots | 3 fl oz | 6 tbsp | 90 ml |
Worked example: if a cocktail recipe calls for 1 shot of whiskey, measure 1.5 fl oz. If you do not have a jigger, use 3 tablespoons.
Worked example: if a recipe calls for a double shot of tequila, measure 3 fl oz. That is the same as 6 tablespoons, or just under 1/2 cup.
Be careful with 1/4 cup. A 1/4 cup is 4 tablespoons, which equals 2 fluid ounces. That is larger than a single shot by 0.5 fl oz.
So if you fill a 1/4 cup and call it one shot, you are pouring 33% more than a 1.5-ounce standard shot.
Why Shot Glasses Can Be Confusing
Not every shot glass holds exactly one standard shot. Some small glasses hold 1 fl oz, while many bar-style shot glasses hold 1.5 fl oz.
A 1-ounce shot glass holds only 2 tablespoons. That is 1 tablespoon less than a standard 1.5-ounce single shot.
A tall shot glass may hold 2 fl oz. That equals 4 tablespoons, so filling it to the rim is not a standard single shot.
For a true double shot, do not assume “two glasses” unless you know the glass size. Two 1-ounce glasses equal 2 fl oz, not a 3-ounce double.
The most reliable kitchen shortcut is this: single shot = 3 tablespoons; double shot = 6 tablespoons.
If measuring several drinks, scale directly. Four single shots equal 6 fl oz, which is 12 tablespoons, or about 180 ml.
Eight single shots equal 12 fl oz, or 24 tablespoons. Since 1 cup is 8 fl oz, that is 1 1/2 cups.
For batching, three double shots equal 9 fl oz. That is 18 tablespoons, or about 270 ml.
Bottom line for U.S. measuring: use 1.5 fl oz for a single shot and 3 fl oz for a double shot unless a recipe states a different size.
How To Measure A Shot
A standard U.S. shot is usually treated as 1.5 fluid ounces. Using the supplied conversions, that equals 3 tablespoons or 45 ml, because 1 fluid ounce is 2 tablespoons, and 1 tablespoon is 15 ml.
Fast Method With Tablespoons
- 1. Pick the target pour: For a standard shot, measure 1.5 fluid ounces. That is the same as 3 tablespoons or 45 ml. For a smaller 1-ounce pour, measure 2 tablespoons or 30 ml.
- 2. Use level tablespoons: Fill 1 tablespoon to the rim, not heaped and not short. Repeat 3 times for a 1.5-ounce shot. Each tablespoon is 15 ml, so 3 tablespoons gives 45 ml.
- 3. Convert if your tool shows ounces: If your jigger or cup has fluid-ounce marks, fill to 1.5 fluid ounces. Since 1 fluid ounce equals 2 tablespoons, 1.5 fluid ounces equals 3 tablespoons.
- 4. Convert if your tool shows milliliters: Fill to 45 ml for a standard shot. Use 30 ml for a 1-ounce shot. Use 15 ml if a recipe calls for 1 tablespoon of liquor.
- 5. Check oversized shot glasses: Many shot glasses hold more than 1.5 fluid ounces when filled to the lip. Measure water into the glass first: 3 tablespoons means the standard-shot line is reached.
- 6. Mark the true fill line: After adding 3 tablespoons of water to an empty shot glass, note the height. That line is your 1.5-ounce reference for future pours.
- 7. Scale for multiple drinks: Multiply the shot size by the number of servings. Four standard shots are 6 fluid ounces, which equals 12 tablespoons or 180 ml.
Common Shot Measurements
| Pour | Fluid ounces | Tablespoons | Milliliters |
|---|---|---|---|
| Half-ounce splash | 0.5 fl oz | 1 tbsp | 15 ml |
| Small shot | 1 fl oz | 2 tbsp | 30 ml |
| Standard shot | 1.5 fl oz | 3 tbsp | 45 ml |
| Double standard shot | 3 fl oz | 6 tbsp | 90 ml |
Worked example: a cocktail needs 2 standard shots of tequila. Measure 6 tablespoons total, because each standard shot is 3 tablespoons. In metric, pour 90 ml total.
Another example: if a recipe says 1/4 cup of liquor, that is 4 tablespoons or 59 ml. Since a standard shot is 3 tablespoons, 1/4 cup is more than 1 standard shot.
If your shot glass has a thick base, do not estimate from the outside height. Measure liquid volume, not glass size. A tall, narrow glass and a short, wide glass can hold the same 1.5 fluid ounces.
For the most repeatable result, use a tablespoon set or a marked jigger. Free-pouring into a shot glass is less precise unless you have already measured and marked the 45 ml fill line.
Shot Glass Size Quick Chart
Standard U.S. shot glass: 1.5 fluid ounces. That equals 3 tablespoons, or about 45 ml using the kitchen conversion 1 fl oz = 2 tbsp = 30 ml.
| Shot glass fill | Fluid ounces | Tablespoons | Approx. milliliters |
|---|---|---|---|
| Small shot | 1 fl oz | 2 tbsp | 30 ml |
| Standard U.S. shot | 1.5 fl oz | 3 tbsp | 45 ml |
| Double shot | 2 fl oz | 4 tbsp | 59 ml |
| Half cup equivalent | 4 fl oz | 8 tbsp | 118 ml |
Fast Answer For Measuring
If a recipe says “1 shot,” measure 1.5 fl oz unless it gives another size. In kitchen spoons, that is exactly 3 tablespoons.
If you do not have a shot glass, use a tablespoon. Fill it 3 times for one standard shot. Fill it 2 times for a 1 fl oz pour. Fill it 4 times for a 2 fl oz double.
A standard shot is less than 1/4 cup. Since 1/4 cup is 4 tablespoons, and a standard shot is 3 tablespoons, it is 1 tablespoon short of 1/4 cup.
Worked Examples
Example 1: A cocktail calls for 2 shots. Use 3 fl oz total, because 1.5 fl oz × 2 = 3 fl oz. In tablespoons, that is 6 tablespoons.
Example 2: A sauce calls for 1/2 shot. Use 0.75 fl oz. Since a full shot is 3 tablespoons, a half shot is 1.5 tablespoons.
Example 3: You have a 1/4 cup measure. Fill it 3/4 full to approximate a standard shot, because 1/4 cup is 4 tablespoons and a shot is 3 tablespoons.
Example 4: A recipe needs 4 standard shots. Use 6 fl oz total. That is 12 tablespoons, or 3/4 cup because 1 cup is 16 tablespoons.
Common Edge Cases
Some shot glasses look full at 1 fl oz, while others hold 2 fl oz to the rim. Do not assume the rim equals one standard shot unless the glass is marked.
A “double shot” is usually measured as 2 fl oz in kitchen terms here. That equals 4 tablespoons, the same volume as 1/4 cup.
If a recipe lists ml instead of ounces, use the nearest kitchen conversion: 1 fl oz is 30 ml, so a 1.5 fl oz standard shot is about 45 ml.
For baking, syrups, coffee drinks, and sauces, measure the shot instead of free-pouring. A 2 fl oz pour instead of 1.5 fl oz adds 1 extra tablespoon.
Fluid Ounces Versus Weight Ounces
A standard U.S. shot glass is measured by volume, not weight. In bar recipes, “1 shot” usually means 1.5 fluid ounces, written as 1.5 fl oz. That is a liquid volume equal to about 44.36 milliliters.
A fluid ounce is not the same as an ounce on a kitchen scale. A U.S. fluid ounce measures space: 1 fl oz = 29.5735 mL. A weight ounce measures mass: 1 oz = 28.3495 g.
Why 1.5 Fluid Ounces Does Not Always Weigh 1.5 Ounces
The weight of a shot depends on the liquid’s density. A 1.5 fl oz shot always has the same volume, but water, alcohol, cream, and syrup will not all weigh the same amount.
Worked example with water: 1.5 fl oz × 29.5735 mL = 44.36 mL. Since water is about 1 g per mL, that shot weighs about 44.36 g.
Convert that water weight to ounces: 44.36 g ÷ 28.3495 g per oz = 1.56 oz by weight. So a 1.5 fl oz shot of water weighs about 1.56 oz, not exactly 1.5 oz.
Worked example with pure ethanol: ethanol has a density of about 0.789 g per mL at 20°C. A 44.36 mL shot × 0.789 g per mL = about 35.0 g.
Convert that ethanol weight: 35.0 g ÷ 28.3495 = about 1.23 oz by weight. The volume is still 1.5 fl oz, but the scale reads much less than water.
Reading Recipes Correctly
If a cocktail recipe says “1 oz whiskey,” it almost always means 1 fluid ounce, or 29.57 mL. It does not mean weighing 1 oz of whiskey on a scale.
For a standard shot, use 1.5 fl oz, 3 tablespoons, or about 44 mL. Use weight ounces only when a recipe clearly gives grams or says to weigh the ingredient.
Why Shot Glasses Vary
A “standard” shot is not universal. In the U.S., bar recipes commonly use 1.5 U.S. fl oz, which equals 3 tablespoons or about 44 ml. But the glass on the shelf may hold 1 oz, 1.25 oz, 1.5 oz, 2 oz, or more.
Legal standards are not the same everywhere
The U.S. has no single federal shot size. Many American cocktail books and bars treat 1.5 fl oz as the normal pour, but house policy, state rules, and measuring tools can change the actual serving.
Other countries use different measures. In the U.K., spirits are commonly sold as 25 ml or 35 ml singles. In Australia, a standard nip is often 30 ml. Those amounts are smaller than a 1.5 fl oz U.S. shot.
Glass capacity is not the same as pour size
A shot glass labeled 2 oz may be meant to hold 2 oz to the rim, not the serving amount. A bartender may pour 1.5 oz into that glass, leaving headspace so it does not spill.
Example: if a glass holds 2 fl oz to the brim and the bar pours 1.5 fl oz, the empty space is 0.5 fl oz. That is one-third of the poured drink amount, so the glass can look underfilled.
Another example: a 1 oz “pony” shot is 2 tablespoons. Compared with a 1.5 oz shot, it is short by 0.5 oz. That means 3 pony shots equal 2 standard 1.5 oz shots.
Recipes depend on the measure, not the glass
For accuracy, use a jigger. A common double-sided jigger measures 1.5 fl oz on one side and 0.75 fl oz on the other. That keeps a cocktail consistent even if the shot glass size varies.
Common Cocktail Pour Conversions
In U.S. bartending, a standard shot is usually 1.5 fluid ounces. That equals 3 tablespoons, 9 teaspoons, 44.36 milliliters, or 0.1875 cup.
Shot, Jigger, and Ounce Equivalents
A full-size jigger commonly measures 1.5 fl oz on one side and 0.75 fl oz on the other. So 1 standard shot equals the large jigger side, and a half shot equals the small side.
Use these core conversions: 0.5 fl oz = 1 tablespoon = 14.79 ml. 1 fl oz = 2 tablespoons = 29.57 ml. 1.5 fl oz = 3 tablespoons = 44.36 ml.
For smaller pours, 0.25 fl oz equals 1.5 teaspoons. A 0.75 fl oz half-shot equals 1.5 tablespoons, 4.5 teaspoons, or 22.18 ml.
Worked Cocktail Examples
If a margarita recipe calls for 2 fl oz tequila, that is 1 standard shot plus 0.5 fl oz. In tablespoons, it is 4 tablespoons total.
If a Manhattan uses 2 fl oz whiskey and 1 fl oz sweet vermouth, the drink contains 3 fl oz before bitters and dilution. That is exactly 2 standard 1.5 oz shots.
If a recipe lists 45 ml vodka, it is nearly one U.S. standard shot. The exact 1.5 fl oz conversion is 44.36 ml, so 45 ml is only 0.64 ml more.
Batching by the Shot
For 8 drinks using 1.5 fl oz liquor each, multiply 8 by 1.5. You need 12 fl oz, which is 1.5 cups or 354.88 ml.
For 10 cocktails using 0.75 fl oz liqueur each, multiply 10 by 0.75. You need 7.5 fl oz, equal to 15 tablespoons or 221.80 ml.
A 750 ml bottle contains 25.36 U.S. fl oz. Dividing by 1.5 fl oz gives about 16.9 standard shots per bottle.

How many milliliters are in a standard shot glass?
A standard U.S. shot glass is usually about 45 ml. That comes from 1.5 fluid ounces, or 3 tablespoons, with each tablespoon equal to 15 ml. Some shot glasses are smaller, so check markings if precision matters.
How many shots are in a cup?
One U.S. cup is 8 fluid ounces. If each standard shot is 1.5 fluid ounces, a cup holds about 5.33 shots. For kitchen measuring, that means 5 full shots plus about 1 tablespoon more.
How many ounces are in a double shot?
In the U.S., a double shot is usually 3 fluid ounces, based on a 1.5-ounce standard shot. Some bars may pour a 2-ounce double if their house single is 1 ounce, so the exact amount depends on the pour standard being used.
How many ounces are in a jigger?
A common U.S. jigger has two sides: 1.5 fluid ounces on the large side and 0.75 fluid ounce on the small side. Some jiggers are 2 ounces and 1 ounce, so checking the stamped measurement is the most reliable method.
How many standard shots are in a 750 ml bottle?
A 750 ml liquor bottle contains about 25.36 fluid ounces. Using a 1.5-ounce standard shot, that equals about 16 full shots, with a little left over. If using 1-ounce pours, the same bottle contains about 25 shots.
How many calories are in a standard shot of liquor?
A 1.5-ounce shot of 80-proof liquor typically has about 97 calories before mixers. Higher-proof spirits have more calories because alcohol contributes about 7 calories per gram. Sweet liqueurs can be much higher due to added sugar.
