Updated April 2026.
One 1.5-ounce shot of 80-proof (40% ABV) vodka equals one 12-ounce beer at 5% ABV. Both are one US standard drink: about 14 grams, or 0.6 fluid ounces, of pure alcohol (NIAAA, updated December 2025). A light beer at 4.2% is a little less than a shot. An 8% IPA in the same 12-ounce can is closer to 1.6 shots.
The beer does not “equal” the shot because of bubbles or color. It equals the shot when the ethanol matches. Change the can size or the ABV and the ratio moves.
Beer vs a 1.5 oz vodka shot
Standard drinks = (fl oz × ABV) ÷ 0.6. One vodka shot at 1.5 oz × 0.40 = 0.6 oz of alcohol.
| Beer | Can/bottle | ABV | Std drinks | Beers to match one vodka shot |
|---|---|---|---|---|
| Regular beer (NIAAA reference) | 12 oz | 5% | 1.00 | 1.0 |
| Typical US light beer | 12 oz | 4.2% | 0.84 | 1.2 |
| Malt liquor (NIAAA band) | 8–10 oz | ~7% | ~1.0 | ~1.0 at that pour |
| Craft IPA example | 12 oz | 7% | 1.40 | 0.7 |
| Strong IPA / DIPA example | 12 oz | 8% | 1.60 | 0.6 |
| Tallboy regular | 16 oz | 5% | 1.33 | 0.75 |
| Pint of 5% draft | 16 oz | 5% | 1.33 | 0.75 |
| Pint of 5% UK imperial | 20 oz | 5% | 1.67 | 0.6 |
A 12-ounce 4.2% light beer has 12 × 0.042 = 0.504 ounces of alcohol, so you need 0.6 ÷ 0.504 ≈ 1.2 cans to match one 1.5-ounce vodka shot. An 8% twelve-ounce IPA has 0.96 ounces of alcohol — already 1.6 standard drinks, more than a shot.
Shot size still matters
The US bar shot used here is 1.5 fl oz (about 44 mL). A 1-ounce pony of vodka is two-thirds of a standard drink. A 2-ounce double is 1.33 drinks. If the bartender free-pours, the “shot” on the ticket is not a lab measurement. See how many mL is a shot and vodka-shot math.
Why a pint can beat a shot
People treat “a beer” as weaker than “a shot.” Volume is doing the work. Sixteen ounces of 5% beer is 1.33 standard drinks; the vodka shot is 1.0. Sixteen ounces of 7% IPA is 1.87 drinks. The glass looks friendly. The ethanol is not.
Wine is the other NIAAA twin: 5 ounces at 12% ABV is also one standard drink. A restaurant wine pour is often 6 ounces, which is 1.2 drinks. For that comparison see alcohol content in beer vs wine.
This is conversion, not a drinking plan
Matching ethanol does not match how fast you absorb it. Carbonated beer can speed absorption for some people. Food slows it. Body weight, sex, and time still set blood alcohol. Four drinks in about two hours is NIAAA’s binge pattern for women; five is the male pattern. That is a health line, not a target. Do not drive. Legal BAC is 0.08% in most states (0.05% in Utah), and impairment starts earlier.
Read the can. Brewery ABV is on the label because TTB requires an alcohol statement on malt beverages in this range. Guessing “beer is 5%” fails on light lagers and on pastry stouts.
