Board Feet Chart and Calculator

Board foot is a volume measurement used for lumber, where

• 1 board foot = 144 in³ = 1⁄12 ft³ = 2360 cm³ = 2.360 liters = 0.002360 m³

Board feet can be calculated as

BF = w t L / 12                                 (1)

where

BF = board feet

w = nominal lumber width (in)

t = nominal lumber thickness (in)

L = nominal lumber length (ft)

Quick Approximation for Calculating Board Feet

• 1 x 4 - divide linear length (feet) by 3 - (length x 1/3)
• 1 x 6 - divide linear length (feet) by 2  - (length x 1/2)
• 1 x 8 - multiply linear length (feet) by 0.66  - (length x 2/3)
• 1 x 12 - linear length (feet) equals board feet  - (length x 1) 
• 2 x 4 - multiply linear length by 0.66 - (length x 2/3)
• 2 x 6 -  linear length (feet) equals board feet - (length x 1)
• 2 x 8 - multiply linear length by 1.33  - (length x 1 1/3)
• 2 x 12 - multiply linear length by 2  - (length x 2)
