A square foot = 12" x 12"
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
