# Estimate the Volume of Bark as a Percentage Calculator

The volume of bark on a tree varies by species and will vary along the length of the tree. It is almost impossible to calculate exact values. Average bark volume can be estimated with the Dobie and Wright's formula.

This formula will estimate the average bark volume as a percentage of the total volume and as a percentage of the wood volume.

#### Estimating Void Areas

Not all bark is the same. You will have to estimate the void area of the bark.Diameter measurements can be entered in units of inches, centimetres or millimetres.
