Pantry Shelf Calculator

Plan pantry shelving. Enter the pantry size and shelf spacing to get the number of shelves, total shelf length, and rough capacity.

Combined length of all shelves.

Usage Tip

Shallow shelves (about 12 in) beat deep ones for a pantry — you can see and reach everything. Use the deep, hard-to-reach spots for bulk and backup stock.

THE MATH
Shelves = floor(height ÷ shelf spacing)
Linear shelf feet = shelves × width ÷ 12
Shelf area = shelves × width × depth
Shelf spacing is the vertical gap between shelves — about 12 to 16 in for cans and boxes, more for tall bottles, small appliances, or cereal.
The bottom shelf is usually higher off the floor for bulk items; this assumes evenly spaced shelves.
Vary spacing in real life: short shelves for cans and spices, taller ones for appliances and cereal — this estimates even spacing.
Keep shelf depth around 12 to 16 in; deeper shelves bury items at the back where they expire forgotten.
Heavier loads need more supports or thicker material to avoid sagging — see the shelf weight calculator for spans.
