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 “pony” shots or 2-ounce doubles, so check the glass size if precision matters.
How Much Is A Shot Glass In Oz: a standard U.S. shot is 1.5 fluid ounces. That equals 3 tablespoons, 44 milliliters, or 9 teaspoons. If a recipe says “1 shot,” use 1.5 fl oz unless it gives another measure.
Shot glasses are not always identical. Some hold 1 oz, 1.25 oz, 1.5 oz, or 2 oz when filled to the rim. For accurate cooking, cocktails, or baking, check the glass with a liquid measuring cup or use a jigger marked in ounces.
The Short Answer, With Numbers
In the U.S., a standard shot is usually 1.5 fluid ounces. That equals 3 tablespoons, 9 teaspoons, or about 44 milliliters.
A shot glass, however, is not always exactly 1.5 oz. Many hold 1 oz, 1.25 oz, 1.5 oz, or 2 oz. The only way to know your glass is to measure it to the rim.
| Measure | Fluid ounces | Tablespoons | Teaspoons | Milliliters |
|---|---|---|---|---|
| Small shot | 1 oz | 2 tbsp | 6 tsp | 30 mL |
| Common U.S. shot | 1.5 oz | 3 tbsp | 9 tsp | 44 mL |
| Double shot | 3 oz | 6 tbsp | 18 tsp | 89 mL |
| 2-ounce shot glass | 2 oz | 4 tbsp | 12 tsp | 59 mL |
What “one shot” means in practice
If a recipe says “1 shot” without giving ounces, use 1.5 oz as the default U.S. amount. That is the most useful number for cocktails, cooking, and measuring liquor at home.
Example: if a margarita recipe calls for 2 shots tequila, measure 3 oz tequila total. That is 6 tablespoons, or just under 90 mL.
Example: if a sauce calls for ½ shot bourbon, use 0.75 oz. That equals 1½ tablespoons, or about 22 mL.
Example: if a punch recipe calls for 8 shots rum, using the U.S. 1.5 oz standard gives 12 oz rum total. That is 1½ cups.
Shot glass size vs. poured shot
The glass capacity and the serving size are not always the same. A shot glass may hold 2 oz to the rim, while the intended pour may still be 1.5 oz.
A tall, narrow shot glass can look fuller with 1.5 oz than a short, wide glass. Shape changes the visual fill line, not the volume.
If your shot glass has a marked line, use the line instead of the rim. Some 2 oz glasses mark 1 oz and 1.5 oz levels for different pours.
For accuracy, fill the shot glass with water, then pour it into a liquid measuring cup. If it reaches 1.5 oz, it is a standard U.S. shot measure.
If you do not have a shot glass, measure 3 tablespoons for one standard shot. For a double, measure 6 tablespoons.
For mini bottles, a 50 mL bottle is about 1.7 oz. That is slightly more than a 1.5 oz U.S. shot by about 0.2 oz.
Bottom line: when someone asks how much a shot glass is in ounces, the fast U.S. answer is 1.5 oz, unless the glass is labeled otherwise.
Standard Shot Glass Ounces
A standard shot glass in the United States holds 1.5 fluid ounces. That equals 3 tablespoons, 9 teaspoons, or about 44 milliliters.
If a recipe says “1 shot” and gives no other measurement, use 1.5 fl oz as the default U.S. amount. This is the size used for many single mixed drinks and bar pours.
Shot Glass Size Conversions
| Amount | Fluid ounces | Tablespoons | Teaspoons | Milliliters |
|---|---|---|---|---|
| 1 standard U.S. shot | 1.5 fl oz | 3 tbsp | 9 tsp | 44 ml |
| 1 small shot | 1 fl oz | 2 tbsp | 6 tsp | 30 ml |
| 1 double shot | 3 fl oz | 6 tbsp | 18 tsp | 89 ml |
| 1 jigger large side | 1.5 fl oz | 3 tbsp | 9 tsp | 44 ml |
| 1 jigger small side | 0.75 fl oz | 1.5 tbsp | 4.5 tsp | 22 ml |
The confusion comes from the glass itself. Many shot glasses are not filled exactly to the rim for a 1.5-ounce pour, and some decorative shot glasses hold 2 ounces or more when full.
For cooking, measure the liquid, not the glass. A rim-full souvenir shot glass may add 2 fl oz when the recipe expected 1.5 fl oz. That is a 33% increase.
Worked Kitchen Examples
If a marinade calls for 2 shots of bourbon, use 3 fl oz. That is 6 tablespoons, because each standard shot is 3 tablespoons.
If a dessert sauce calls for ½ shot of rum, use 0.75 fl oz. That equals 1½ tablespoons or 4½ teaspoons.
If a punch recipe calls for 8 shots of liquor, use 12 fl oz. That is 1½ cups, since 1 cup is 8 fl oz.
If you only have teaspoons, one standard 1.5-ounce shot is 9 teaspoons. For 3 shots, measure 27 teaspoons, though tablespoons are faster.
Edge Cases: Bar Shot vs Measuring Shot
A “pony shot” is commonly 1 fl oz, not 1.5 fl oz. If a recipe uses “pony” or “small shot,” measure 2 tablespoons.
A “double shot” is usually 3 fl oz in U.S. kitchen math. That is the same as 2 standard shots, 6 tablespoons, or just under 90 ml.
A two-sided jigger often measures 1.5 fl oz on the large side and 0.75 fl oz on the small side. Some jiggers differ, so read the stamped markings.
For accurate recipe results, the safest assumption is simple: 1 shot = 1.5 U.S. fluid ounces. Use a liquid measuring cup, measuring spoons, or a marked jigger when precision matters.
US Shot Size Variations
In the US, a “shot” is not one fixed legal size. The most common bar pour is 1.5 US fluid ounces, but you will also see 1 oz, 1.25 oz, 1.75 oz, and 2 oz pours.
A US fluid ounce is 29.5735 mL. So a standard 1.5 oz shot equals 44.36 mL. If a recipe says “1 shot” and gives no other detail, use 1.5 fl oz unless the context says otherwise.
| US shot amount | Milliliters | Where you may see it |
|---|---|---|
| 1 oz | 29.57 mL | Small pour, tasting pour, some measured cocktails |
| 1.25 oz | 36.97 mL | Common controlled-pour size in some bars |
| 1.5 oz | 44.36 mL | Typical US “standard shot” |
| 1.75 oz | 51.75 mL | Larger house pour or cocktail build |
| 2 oz | 59.15 mL | Double-style pour, rocks pour, some cocktail specs |
Why Your Shot Glass May Not Equal One Shot
Many shot glasses are sold as 1.5 oz glasses, but the line of liquid matters. Filled to the rim, some hold 1.75 oz or 2 oz. A “full shot glass” can overpour a recipe by 0.25 to 0.5 oz.
Example: if your shot glass holds 2 oz to the brim, and a drink calls for 1 shot of whiskey, filling it full gives 2 oz, not 1.5 oz. That is 33% more liquor than the standard shot.
If a cocktail calls for 2 shots, the difference grows fast. Two standard shots are 3 oz. Two brim-full 2 oz glasses are 4 oz. That adds an extra 1 oz, equal to two-thirds of a standard shot.
Single, Double, and Pony Shot Amounts
A “single” in the US usually means 1.5 oz, but not always. Some bars use 1.25 oz as the house single. Others pour 1 oz for high-proof spirits, tastings, flights, or promotional drinks.
A “double” often means 3 oz if based on a 1.5 oz single. But in some bars, a double may be 2 oz, especially where the house single is 1 oz. Always check the menu or measured pour.
A “pony shot” is commonly 1 oz. In older recipes, “pony” may appear where a smaller measure is intended. For modern home mixing, treat pony as 1 fl oz unless the recipe states otherwise.
Worked Recipe Conversions
If a recipe says 1 shot vodka, use 1.5 oz or 44.36 mL. If it says 1/2 shot, use 0.75 oz or 22.18 mL. If it says 2 shots, use 3 oz or 88.72 mL.
For a party batch calling for 8 shots of tequila, standard US math is 8 × 1.5 oz = 12 oz. In milliliters, that is about 355 mL. A 750 mL bottle would cover about 16 standard shots.
Edge case: airline mini bottles are often 50 mL. That equals 1.69 US fl oz. One mini bottle is larger than a 1.5 oz shot by 0.19 oz, or about 5.6 mL.
For accurate mixing, use a jigger marked in ounces. If using only a shot glass, measure it once with water: 3 tablespoons equal 1.5 fl oz, since 1 tablespoon equals 0.5 fl oz.
How To Measure A Shot
A standard U.S. shot is usually 1.5 fl oz, equal to 3 tablespoons, 44.36 mL, or 9 teaspoons. Some bars pour 1.25 oz or 2 oz, so decide the target size before measuring.
Fast Method With Common Kitchen Tools
- 1. Pick the shot size. Use 1.5 fl oz for a typical U.S. shot. Use 1 fl oz for a small shot, 1.25 fl oz for a conservative bar pour, or 2 fl oz for a large “double-style” pour.
- 2. Use a liquid measuring cup for best accuracy. Set it on a flat counter. Pour until the bottom of the liquid curve, called the meniscus, lines up with 1.5 fl oz.
- 3. If using tablespoons, measure 3 level tablespoons. In U.S. measures, 1 tablespoon equals 0.5 fl oz. So 3 tablespoons equals 1.5 fl oz exactly.
- 4. If using teaspoons, measure 9 level teaspoons. One U.S. teaspoon equals 1/6 fl oz. Nine teaspoons equals 1.5 fl oz.
- 5. If using milliliters, measure 44 mL for a practical shot. The exact conversion is 44.36 mL, but most kitchen cups and jiggers mark 44 or 45 mL.
- 6. If using a jigger, check both sides. A common jigger has 1.5 oz on one side and 0.75 oz on the other. Some have 1 oz and 2 oz, so read the stamp before pouring.
- 7. For repeated shots, fill once and mark the glass. Measure 1.5 oz with a cup, pour it into the glass, then note the height. That mark is only valid for that exact glass.
Worked Examples
Example 1: A cocktail calls for 2 shots of vodka. If one shot is 1.5 oz, pour 3 fl oz total. That is 6 tablespoons or about 89 mL.
Example 2: A recipe calls for 1/2 shot of rum. Half of a 1.5 oz shot is 0.75 oz. That equals 1 1/2 tablespoons, 4 1/2 teaspoons, or about 22 mL.
Example 3: You have a 2 oz shot glass but need a standard 1.5 oz shot. Fill it three-quarters full, not to the rim. For accuracy, measure 1.5 oz once and remember the fill line.
Edge case: A “shot glass” is not always one shot. Many souvenir shot glasses hold 2 oz or more. If the glass is filled to the top, you may be pouring more than a standard shot.
Edge case: Do not measure a shot by weight in ounces. Fluid ounces measure volume. A 1.5 fl oz pour is not always 1.5 oz by weight, because liquids have different densities.
Best quick answer: Measure one U.S. shot as 1.5 fl oz, 3 tablespoons, 9 teaspoons, or about 44 mL.
Shot Glass Size Chart
In the U.S., a standard shot is 1.5 fluid ounces. That equals 3 tablespoons, 9 teaspoons, 44.36 mL, or 1/16 of a 24 fl oz bottle.
| Shot label | Fluid ounces | Tablespoons | Teaspoons | Milliliters |
|---|---|---|---|---|
| Small shot | 1 oz | 2 tbsp | 6 tsp | 29.57 mL |
| Standard U.S. shot | 1.5 oz | 3 tbsp | 9 tsp | 44.36 mL |
| Large shot | 2 oz | 4 tbsp | 12 tsp | 59.15 mL |
| Double shot, U.S. | 3 oz | 6 tbsp | 18 tsp | 88.72 mL |
| Half shot | 0.75 oz | 1.5 tbsp | 4.5 tsp | 22.18 mL |
| Jigger small side | 0.75 oz or 1 oz | 1.5 tbsp or 2 tbsp | 4.5 tsp or 6 tsp | 22.18 mL or 29.57 mL |
| Jigger large side | 1.5 oz or 2 oz | 3 tbsp or 4 tbsp | 9 tsp or 12 tsp | 44.36 mL or 59.15 mL |
What to Use as the Default
Use 1.5 fl oz when a U.S. recipe says “1 shot” and gives no other amount. This is the most useful kitchen conversion because it maps cleanly to tablespoons: 1 shot = 3 tbsp.
If a cocktail recipe calls for 2 shots of liquor, measure 3 fl oz. That is 6 tablespoons, or just under 89 mL.
If a dessert sauce calls for 1 shot of espresso liqueur, use 1.5 fl oz. If you only have spoons, measure 3 level tablespoons.
Worked Conversions
For 4 standard shots: 4 × 1.5 fl oz = 6 fl oz. That equals 12 tablespoons, 36 teaspoons, or about 177 mL.
For 6 standard shots: 6 × 1.5 fl oz = 9 fl oz. That equals 18 tablespoons, which is 1 cup plus 2 tablespoons.
For 8 standard shots: 8 × 1.5 fl oz = 12 fl oz. That is 1 1/2 cups, or about 355 mL.
For 1/2 shot: 1.5 fl oz ÷ 2 = 0.75 fl oz. Measure 1 tablespoon plus 1 1/2 teaspoons.
For 1/3 shot: 1.5 fl oz ÷ 3 = 0.5 fl oz. Measure 1 tablespoon, because 1 tablespoon equals 0.5 fl oz.
Edge Cases: Glass Capacity vs. Measured Shot
A “shot glass” may hold more than one measured shot. Many souvenir or heavy-bottom glasses hold 2 fl oz to the rim, even though a poured shot may be 1.5 fl oz.
Do not use the rim as the measuring line unless the glass is marked. A 2 fl oz glass filled 3/4 full is roughly 1.5 fl oz, but the shape can make that estimate inaccurate.
A “pony shot” is commonly 1 fl oz. In a recipe, that is 2 tablespoons. It is smaller than a standard U.S. shot by 0.5 fl oz, or 1 tablespoon.
A “double” is usually 3 fl oz if based on the U.S. 1.5 oz shot. Some bars pour a 2 oz double when their house shot is 1 oz, so recipes should list ounces, not just “double.”
For kitchen accuracy, use a liquid measuring cup for 2 oz or more, and measuring spoons for 1.5 oz or less. For a standard shot, the fastest exact measure is 3 tablespoons.
Common Pouring Mistakes
The biggest mistake is assuming every shot glass holds 1.5 oz. In the U.S., 1 standard shot is commonly 1.5 fl oz, but many glasses are 1 oz, 1.25 oz, 2 oz, or decorative sizes with no fill line.
If your recipe says “1 shot” and means 1.5 oz, using a 1 oz glass under-pours by 0.5 oz. That is a 33% short pour. In a 4-drink batch, you would miss 2 full ounces of liquor.
The opposite error is using a 2 oz shot glass as if it were 1.5 oz. That adds 0.5 oz per drink. After 6 drinks, that is 3 extra ounces, equal to 2 standard 1.5 oz shots.
Reading the Rim Instead of Measuring
Many shot glasses flare outward. Filling to “near the top” can change the pour by 0.25 to 0.5 oz. A glass that looks 90% full may not be 90% of its volume if the upper half is wider.
Example: a tapered 2 oz shot glass filled halfway by height may hold about 0.75 oz, not 1 oz. The wide top holds more volume than the narrow base, so height is a poor guide.
For accuracy, measure once with water. Fill the glass to your usual line, then pour it into a liquid measuring cup or jigger. Mark the true 1 oz, 1.5 oz, and 2 oz levels if the glass is unmarked.
Confusing Fluid Ounces and Weight Ounces
A shot is measured in fluid ounces, not weight ounces. 1.5 fl oz is a volume. It does not always weigh 1.5 oz on a kitchen scale because alcohol, syrup, cream, and juice have different densities.
If you weigh liquor to fake a shot, the number will be off unless you know the ingredient’s density. Use a jigger, measuring spoon, or marked cup instead of a scale for cocktail volumes.
Using Tablespoons Without Converting
In U.S. measures, 1 fl oz equals 2 tablespoons. A 1.5 oz shot equals 3 tablespoons. A 2 oz pour equals 4 tablespoons. This is useful when you do not have a jigger.
| Pour | Fluid ounces | Tablespoons |
|---|---|---|
| Small shot | 1 oz | 2 tbsp |
| Common U.S. shot | 1.5 oz | 3 tbsp |
| Double | 3 oz | 6 tbsp |
A common batching mistake is multiplying glasses, not ounces. For 8 drinks at 1.5 oz each, you need 12 fl oz liquor. If you pour 8 “shots” from a 2 oz glass, you will use 16 fl oz.
That 4 oz difference matters. It is nearly 3 extra 1.5 oz shots, and it can throw off sweetness, acidity, dilution, and serving count in a punch or margarita batch.
Ignoring Jigger Line Markings
Many jiggers are 1 oz on one side and 1.5 oz on the other, but others are 0.75 oz and 1.25 oz, or 1 oz and 2 oz. Some have internal lines at 0.5 oz or 0.75 oz.
Check the stamped numbers before pouring. A “large side” is not always 1.5 oz. If a recipe needs 1.5 oz and your jigger side is 2 oz, stop at the internal 1.5 oz line or use 3 tablespoons.
Free-pouring is the least reliable edge case. A 4-count pour might be 1 oz for one person and 1.75 oz for another. Spout speed, bottle angle, and liquid thickness all change the result.
For recipes, nutrition estimates, and consistent drinks, define the shot as a number: 1 oz, 1.5 oz, or 2 oz. Do not treat “a shot glass” as a measurement unless you have tested its actual capacity.
Frequently Asked Questions
How many ounces are in a standard shot glass?
In the U.S., a standard shot is usually 1.5 fluid ounces. Many shot glasses hold exactly 1.5 oz, but some decorative or oversized ones hold 2 oz or more. For recipes or cocktails, measure 1.5 fl oz unless the recipe says otherwise.
Is a shot glass 1 oz or 1.5 oz?
A shot glass can be either, but the common U.S. serving size is 1.5 oz. A 1 oz pour is often called a small shot, single ounce, or pony shot. Check the glass line or measure with a jigger if accuracy matters.
How many tablespoons are in a shot glass?
A 1.5 oz U.S. shot equals 3 tablespoons, because 1 fluid ounce equals 2 tablespoons. If your shot glass is 1 oz, it equals 2 tablespoons. This conversion is useful for cocktail recipes, sauces, and dessert flavorings.
How many milliliters are in a shot glass?
A standard U.S. 1.5 oz shot is about 44 ml. A 1 oz shot is about 30 ml, and a 2 oz shot is about 59 ml. If you are following an international recipe, use milliliters for the most consistent measurement.
How can I measure a shot without a shot glass?
Measure 1.5 oz using 3 tablespoons, 9 teaspoons, or about 44 ml. A liquid measuring cup with ounce markings also works. For cocktails, a jigger is best because many have 1 oz and 1.5 oz sides.
