Bonsai Proportions Calculator

To look their best, bonsai trees need to have the right balance and symmetry. The calculators below will help you determine the correct proportional height of the bonsai tree for a given trunk width and where the first branch should be located on the trunk for symmetrical proportions for a given tree height. Or, to calculate pot size, try the bonsai pot size calculator.

Bonsai Height vs Trunk Width

Enter the diameter of your bonsai's trunk at the base to calculate the recommended height that the tree should be.

Given a trunk diameter of 0 inches, a proportional height for your bonsai tree would be approximately 0 inches.

Determining the Height of the First Branch

Enter the height of your bonsai tree to determine the ideal height from the base that the first branch should be located.

Given a bonsai tree height of 0 inches the first branch should be between 0 and 0 inches up from the base of the trunk.
