Loaf Pan Size & Volume Conversion (US & Metric)

A guide to common loaf pan sizes in inches and their metric centimeter equivalents, along with their approximate volumes in US cups and milliliters (ml). Standard depth is usually 2.5 to 3 inches.

Pan Size (Length x Width x Depth approx.)	Metric Size (cm) (approx.)	Volume (US Cups) (approx.)	Volume (ml) (approx.)	Common Use
8 x 4 x 2.5 inches	20 x 10 x 6 cm	4-5 cups	950-1200 ml	Small loaf / Quick bread
8.5 x 4.5 x 2.5 inches	21.5 x 11.5 x 6 cm	6 cups	1400 ml	Standard "1 lb" loaf

10 x 5 x 3 inches	25 x 13 x 7.5 cm	10 cups	2400 ml	Large loaf

Important Considerations for Loaf Pan Volumes:

Loaf pan dimensions can vary slightly between manufacturers. Always check the dimensions stamped on your pan if possible.
The stated "1 lb" or "1.5 lb" loaf size is a general guideline for yeasted breads and doesn't directly equate to the pan's liquid volume capacity.
Pan volumes are approximate. Depth is a critical factor.
When substituting loaf pans, consider both volume and surface area, as these affect baking time and texture.
Fill loaf pans about 1/2 to 2/3 full for quick breads, and allow more room for yeasted breads to rise.
