What this calculator does
Calculates Tree Planting Spacing & Seedlings Required per Acre Sizer using the formula verified against the cited source.
What your result means
An estimate from the inputs you enter, within the scope stated below — not advice.
Formula
Planting spots per acre = 43,560 ÷ (row spacing × within-row spacing, ft); seedlings = plantable acres × spots/acre × (1 + replacement allowance)
The step-by-step working for your own numbers appears with the result above and in the PDF report.
Frequently asked questions
Symbols and assumptions
- Inputs
- The values entered in the fields above
- • Theoretical rectangular-grid planting positions per acre=43,560/(row spacing ft×within-row spacing ft). Required seedlings=plantable acres×positions/acre, with a separately stated replacement/survival allowance if requested.

- • Density formula is supported, but total seedlings requires plantable acreage absent from inputs. Add acreage or rename output seedlings/acre. Roadways, buffers, mortality and establishment targets require separate adjustments; use positive spacings and consistent units.
Important limitation
This is an educational estimate based only on the values and formula shown. Verify current rates, rules, units, and professional standards before relying on the result. It is not personalized financial or investment advice.
