Calculate trees per acre from spacing on square and triangular layouts, plus total trees for a planting area.
Result
How to use this tool
Enter the planned distance between trees in feet.
Compare square and triangular counts.
Enter planting acres for total tree numbers.
Add for access rows, edges and establishment losses.
Formula & worked example
At 10 ft spacing, a square layout gives 435.6 trees per acre and a triangular layout 502.9.
Limitations — read this before you rely on it
Assumes uniform spacing over the full area. Access rows, edges, water and unplantable ground reduce the true count.
Frequently asked questions
Rows are offset so each tree sits in a triangle, fitting about 15% more trees.
It closes canopy sooner but increases competition and thinning needs.
Orchard spacing follows rootstock and pruning system; use the mature canopy width as a guide.
No. Subtract roads and rides from the planting area first.
Order 5–10% extra for losses in the first years.
