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.
