A square meter = 3' x 3'

1 Acre = 43,560 square feet or 14,520 square meters

How to calculate the square footage of a garden bed or row

• Multiply the length x width (for rows only measure growing space not pathways)

• Examples:

• A raised bed measuring 4' x 8' = 32 sq. ft

• A planting bed / row measuring 10' long by 3' wide = 30 square feet

• Common row lengths for market gardeners:

• 3' x 50' = 150 sq. ft. (3' x 100' = 300 sq. ft.)

• 4' x 50' = 200 sq. ft. (4' x 100' = 400 sq. ft.)

How to Calculating Volume for a raised bed: 

• length x width x height = cu. ft.

• example: a raised bed measuring 4’ x 4’ x 6” deep = 8 cu. ft.

• 1/2 cu.ft. = app. 5-Gallon
