Dinner Rolls Calculator
Dinner roll counts, dough, and butter for any guest count.
What it does
Roll baskets empty fast at holidays. Counts from guests times appetite keep dough and butter matched.
The tool above scales the basket. Twenty guests at 1.5 each need 30 rolls from 2.7 lb of dough with 15 tbsp of butter. The metric match is 1.2 kg with 213 g.
Rolls run one to two per guest. Dinners take one, holidays one and a half, and roll lovers two.
Dough runs nine hundredths pound each. Buttery enriched doughs bake golden at 350 F.
Warm baskets win. Butter melting into hot rolls beats cold piles.

Quick checks. Answers sit tucked under each question.
12 guests, 1 each?
round(12 x 1) = 12 rolls. Dough is 12 x 0.09 = 1.1 lb after rounding (1.08). Butter is 12 x 0.5 = 6 tbsp.
40 guests, 2 each?
round(40 x 2) = 80 rolls. Dough is 80 x 0.09 = 7.2 lb.
