About this calculator
This tool applies simple height, root-habit and feature multipliers to produce illustrative starting distances. It is not a safety clearance or site-specific recommendation: tree roots and mature canopy vary by species and site. Check the species’ mature spread, locate underground utilities before digging, and follow utility-provider and local guidance for overhead lines and structures.
Worked example
calculated with the default values below
Mature tree height 40 ft · Root habit Moderate · Distance from House with foundations Mature canopy spread 32.0 ft · Minimum distance from the canopy 11.2 ft · Minimum distance for roots 16.0 ft · Illustrative starting distance 25.6 ft

Disclaimer
These are general gardening estimates. Planting windows, growth, water and nutrient needs vary by place and plant. Check local extension guidance and product labels before acting on an estimate.

This record describes the implementation used by this page. It is not independent validation. External references, when available, support only the stated formula or definition; estimates and custom rules retain their own assumptions.
Formula and variables
S = 0.8H; C = 0.35Hh; R = 0.5Hh; D = Rr
- H
- Mature height
- h
- Root-habit factor
- r
- Nearby-feature factor
- S

- Illustrative starting distance
Illustrative multipliers only; this does not calculate overhead-line clearance. Confirm species mature spread, underground utility locations, and local/provider clearance requirements before planting.
Frequently asked questions
How should I use the suggested tree distances?
They are illustrative starting distances based on mature height and selected factors, not species-specific advice or utility-line clearance. Check mature spread, underground services, and local or provider clearances before planting.
