Burger Patty Calculator
Burger patties, ground meat, and buns for any cookout size.
What it does
Burger math keeps the grill calm. Patties portioned before guests arrive cook in even waves, while a short count sends the cook back to the store mid party.
The tool above multiplies guests by appetite and patty size. Ten guests at 2 each with 5 oz patties need 20 patties, or 6.3 lb, plus 22 buns. The metric match is 20 patties at 142 g for 2.8 kg.
Appetite sets the middle. One each suits lunches with sides, 2 suit dinner cookouts, and 3 suit teens and late nights. Kids often take one small patty, which the per person average absorbs.
Patty size sets the meat. Five ounce patties suit standard buns, quarter pounders suit classic builds, and 2 oz sliders need their own count.
Buns add two spare. Torn, dropped, and extra hungry plates always claim a couple, so patties plus two keeps the table whole.

Worked example
Example: 10 guests, 2 each
Imperial defaults: 10 guests, 2 patties each, 5 oz patties. These are also the default values, so the page opens on this answer.
- Guests: 10.
- Each: 2 patties.
- Patties: 10 x 2 = 20 patties.
- Meat: 20 x 5 oz = 100 oz, or 100 / 16 = 6.3 lb.
- Buns: 20 + 2 spare = 22 buns.
- Tool shows 20 patties, 6.3 lb, 22 buns.
Reference table

Limits
- Counts only. Grill waves and temps need plans.
- Shrink varies by fat share and style.
- Sides, cheese, and veg need own counts.
- Allergies need separate buns and tools.
Common mistakes
- Planning 1 each for a dinner cookout.
- Buying buns exact with no spare.
- Pressing patties flat on the grill and drying them.
- Mixing raw and cooked tools.
- Holding cooked patties in danger temps.
Try it yourself
Quick checks. Answers sit tucked under each question.
15 guests, 2 each, 5 oz?
15 x 2 = 30 patties. Meat is 30 x 5 = 150 oz, or 150 / 16 = 9.4 lb. Buns are 30 + 2 = 32.
10 guests, 1 each, 142 g?
10 x 1 = 10 patties. Meat is 10 x 142 = 1420 g, or 1.4 kg. Buns are 10 + 2 = 12.
Questions
Meat for 10 guests?
Multiply guests by patties each. Ten guests at 2 need 20 patties, or 6.3 lb at 5 oz each.
Patties to pounds?
Divide patty ounces by 16. Here 100 / 16 = 6.3 lb.
Patties per person?
Plan 1 each for lunch with sides, 2 for dinner cookouts, 3 for hungry crowds. Kids often eat 1 small.
How many buns?
Patties plus 2 spare. Here 20 + 2 = 22 buns.
Does patty style matter?
Yes. Smash styles shrink more and cook faster, thick pub styles shrink less.
Does this time grilling?
No. Grill space and safe temps need their own plans.
