Tree Spacing Calculator

Calculate tree spacing, trees per acre, total trees needed, planting area, row count, tree count per row, and estimated planting cost. Use this tree spacing calculator for orchards, windbreaks, reforestation, woodlots, shade trees, landscaping, and garden planting layouts.

Calculate Tree Spacing

Trees Per Acre = 43,560 ÷ (Tree Spacing × Row Spacing).

How the tree spacing calculator works

Trees from spacing:
The calculator divides the planting area by the square feet used by each tree to estimate total trees needed.

Spacing from target trees:
Enter a target number of trees and the calculator estimates the average square spacing needed for that planting density.

Rectangle planting layout:
Enter planting length and width to estimate the number of rows, trees per row, and total layout capacity.

Cost estimate:
The calculator multiplies total trees by tree cost and planting cost to estimate total project cost.

Why use a tree spacing calculator?

A tree spacing calculator helps plan how many trees can fit in a planting area before ordering trees, laying out rows, or estimating project costs.

It can be useful for orchards, windbreaks, privacy screens, reforestation, woodlots, Christmas tree farms, landscape projects, and wildlife habitat plantings.

What your result means

Your result shows total trees needed, trees per acre, area per tree, surviving trees, replacement trees, row count, trees per row, total planting cost, and cost per acre. These numbers are estimates based on the spacing, planting area, survival rate, and costs you enter.

Frequently asked questions

How do you calculate trees per acre?

Multiply tree spacing by row spacing to find square feet per tree, then divide 43,560 square feet by that number.

How many trees fit on one acre at 10 by 10 spacing?

At 10 ft by 10 ft spacing, each tree uses 100 square feet. One acre can fit about 435 trees before adjustments for borders, roads, or unused space.

What spacing should I use for trees?

Tree spacing depends on the species, mature canopy size, purpose, equipment access, sunlight, soil, and whether the planting is for orchard production, shade, privacy, timber, or wildlife habitat.

Should I include a survival rate?

Yes. A survival rate helps estimate how many planted trees may remain after establishment and how many replacements may be needed.
