How Many Ounces Are in a Shot?
Quick Answer: 1.5 fl oz in 1 US shot · 44 mL · espresso shot = 1 fl oz
At a glance
- US standard shot (liquor) = 1.5 fl oz (44 mL) (bar industry convention, not federal law)
- Espresso shot = 1 fl oz (30 mL) (smaller because the drink is more concentrated)
- By country: UK 25 mL · Germany 20 mL · Australia 30 mL · France 35 mL (no international standard — always varies)
A standard US shot is 1.5 fluid ounces, or about 44 mL. This is the number behind every cocktail recipe that says "1 shot of vodka" — but it\'s a convention, not a law. The US has no federally mandated shot size, which is why one bar\'s pour can be noticeably different from another\'s. Espresso shots are a separate thing at 1 fl oz (30 mL), and shot sizes vary even more dramatically by country. The 1.5-oz number is the one to memorize if you\'re building cocktails at home.

No federal shot standard — why 1.5 oz is convention, not law
The 1.5-oz US shot feels standardized, but it isn\'t. The US has no federal or state law requiring a specific shot size. Contrast this with:
- UK — the Weights and Measures Act requires pubs to pour 25 mL or 35 mL (single), and 50 mL or 70 mL (double). Bartenders must display which size they use.
- Australia — 30 mL is the federal standard "nip"; 60 mL for a double.
- Germany — varies by region and drink. Schnapps is 20 mL; herbal liqueurs often 40 mL.
- US — nothing is mandated. Bars pour what they think is right. The 1.5 oz figure comes from long bar-industry custom and is the pour size recognised in federal weights-and-measures references, but it\'s not legally required.
The practical implication: if a cocktail tastes too strong or too weak at different bars, it\'s probably not your imagination — pour sizes genuinely differ. Some cost-conscious bars pour 1 oz. Some generous neighbourhood bars pour closer to 2 oz. At home, use a jigger with clearly marked lines (1 oz on one side, 1.5 oz on the other is the most common pairing).
How many shots are in a bottle?
For party planning or stock-taking, the question flips: given a bottle of liquor, how many shots can you pour from it? The answer depends on the bottle size. Here are the common sizes.
| Bottle size | Also called | 1.5 oz shots | 1 oz shots |
|---|---|---|---|
| 50 mL | Mini / airplane bottle | ~1 shot | 1.7 shots |
| 200 mL | Half-pint / hip flask | ~4 shots | 6-7 shots |
| 375 mL | Pint / "half fifth" | ~8 shots | 12-13 shots |
| 750 mL | Fifth (standard) | ~16 shots | 25 shots |
| 1,000 mL (1 L) | Litre | ~22 shots | 33 shots |
| 1,750 mL | Handle / half gallon | ~39 shots | 59 shots |
Numbers round down to account for spillage, bottle residue, and the way real pours rarely hit exact measurements. Bartenders estimate 15-16 shots per 750 mL for planning purposes. For cocktails that use multiple types of spirits, divide each bottle\'s shot count by the number of spirits per drink.
Did you know?
The word "shot" for a small pour of liquor appears in American English by the late 1600s, long before bars or standardized measures. One origin story traces it to Old West saloons, where a .45 cartridge was sometimes used as trade currency — a customer could exchange a bullet ("a shot") for a small pour of whiskey. The story is almost certainly folklore, but the alternative etymologies aren't much better documented. The most solid explanation: the word comes from the older English "scot", meaning a payment or one's share of a tavern bill. That gives "shot" the same root as "scot-free" (leaving without paying).
How many mL are in a shot?
A US shot of 1.5 fl oz equals 44.36 mL, which bartenders usually call 44 mL or loosely "45 mL". This is the figure that shows up in international cocktail books that give US recipes in metric. An espresso shot, different kind of shot, is 30 mL (1 fl oz). Don\'t mix them up in a recipe — a cocktail that asks for "1 shot vodka" means 44 mL; a coffee recipe that asks for "1 shot espresso" means 30 mL.
If you\'re converting a recipe from another country, check the origin: UK and Irish bar manuals use 25 or 35 mL. Continental European cocktail books often give 30 mL or 50 mL. Scaling a recipe by matching the country\'s convention is usually more accurate than converting from one country\'s "shot" to another\'s.
How many shots are in an ounce?
An ounce is 2/3 of a US shot (0.67 shots). In reverse terms: 1 fl oz is exactly one espresso-shot size, or two-thirds of a liquor shot. Useful numbers:
- 1 fl oz = ⅔ of a US liquor shot = 1 espresso shot
- 1.5 fl oz = 1 US liquor shot
- 3 fl oz = 1 double shot
- 4 fl oz = about 2.67 shots

Word order matters (shot vs shot glass vs double shot)
- "How many ounces in a shot?" → 1.5 fl oz (the standard US pour)
- "How many ounces in a shot glass?" → usually 1.5 fl oz to the rim, but depends on the specific glass
- "How many ounces in a double shot?" → 3 fl oz at most US bars (some pour 2 fl oz)
- "How many ounces in a shot of espresso?" → 1 fl oz (completely different from liquor)
Ask the bartender or check the glass when in doubt — there\'s no universal answer.
The formula
fl oz = shots × 1.5 (US standard)
The 1.5 multiplier is convention. The US government doesn\'t define a shot legally, but federal weights-and-measures references list it as 1.5 fl oz, and this is what bar and cocktail industry associations use. For espresso, the multiplier is 1.0 (shot = 1 fl oz). When converting from other countries\' shots, use their specific mL value and treat it as a different unit rather than a "shot" per se.
How to measure a shot accurately at home
With a jigger
The standard bartender\'s jigger has two cups welded back-to-back: one holds 1 fl oz, the other holds 1.5 fl oz (sometimes 2 fl oz). Fill to the rim, not above. A proper pour fills to the lip, where the liquid surface is level with the top edge — not a dome above it.
With a shot glass
Shot glasses vary, but most standard ones hold 1.5 fl oz to the rim. Fill to the top if you want a standard shot; pour less if you want a "half shot". Novelty shot glasses, tall shooters, and "double shot" glasses all hold different amounts — a one-time measurement with a kitchen measuring cup tells you what your glass actually holds.
Without any measure
Pour into a small glass for about 2 seconds from a bottle with a standard pour-spout. That gives roughly 1.5 fl oz (1 oz per second is the industry heuristic). This is inaccurate enough that bartenders-in-training practice this on an empty bottle over a measured cup until they can reliably hit 1.5 oz by count. For serious cocktail work, always measure; for a casual shot at a party, counting is fine.
Frequently Asked Questions
How many ounces are in a shot?
A standard US shot is 1.5 fluid ounces (about 44 mL). This is a bar-industry convention, not a federal law — the US has no legally required shot size. Some bars pour 1 fl oz, some pour 2 fl oz, and sizes vary widely by country.
How many ounces are in a shot glass?
Most US shot glasses hold 1.5 fl oz to the rim, matching the standard pour. Some taller "double" shot glasses hold 2 to 3 fl oz. Novelty shot glasses can hold 4 fl oz or more, but those aren't for measuring standard drinks. The only way to know your glass's capacity is to measure it with water once.
How many mL are in a shot?
About 44 mL for a US shot (1.5 fl oz). Different countries use different standards: UK 25 mL, Germany 20 mL or 40 mL, Australia 30 mL, Japan 30 mL, France 35 mL, Italy 30 mL. The US 44 mL shot is one of the largest.
How many shots are in a 750 mL bottle?
About 16 US shots (750 mL ÷ 44 mL = 17, minus spillage and residue). A standard "fifth" of liquor (750 mL) gives you about 16 solid 1.5-oz pours. Planning for a party? Figure 15-16 shots per 750 mL bottle to be safe.
How many ounces are in a double shot?
3 fluid ounces at most US bars — exactly double the standard 1.5 oz pour. Some bars treat 2 fl oz as a "double", which is actually 1.33 standard shots. If you want exact measurements, ask the bartender how they pour doubles.
How many ounces are in an espresso shot?
A single espresso shot is 1 fluid ounce (about 30 mL). A double espresso is 2 fl oz (60 mL). This is a completely different measurement from a liquor shot — espresso shots are smaller because the drink is more concentrated.
Is a shot 1 oz or 1.5 oz?
Both are used, depending on context. 1.5 oz is the US bar standard for liquor and cocktail recipes. 1 oz is common for espresso, some cocktail "dash" measurements, and a few smaller bar pours. When a recipe just says "1 shot", assume 1.5 fl oz unless it's an espresso drink.
Why do shot sizes vary so much by country?
Because there's no international standard. The US, UK, and EU each set their own rules. UK pubs serve 25 mL or 35 mL by law (regulated single/double pours). Germany varies regionally from 20 mL (Steinhäger) to 40 mL. Scandinavia and Russia trend toward 50 mL. The US 1.5-oz standard is just what the bar industry settled on over time; it was never codified federally.
How many shots are in a pint of liquor?
A US pint of liquor is 375 mL (half a fifth) — that gives about 8 standard shots (375 ÷ 44 ≈ 8.5). A "pint" of beer at 16 fl oz is a different kind of pint and isn't measured in shots at all.

This page uses the US bar convention of 1.5 fl oz (44 mL) as the default shot size. The US has no legally required shot size; other countries have different conventions, listed in the "Shot sizes around the world" table above. Espresso shots (1 fl oz / 30 mL) are a distinct measurement from liquor shots. Always check the shot glass or jigger you\'re using — capacities vary.
