Shrub & Hedge Spacing CalculatorEstimate shrub counts for hedges, foundation plantings and mass beds by mature width, with linear-foot hedge length and staggered mass-planting quantities.Free shrub & hedge spacing calculator with formulas, waste factors, cost estimates and professional guidance.Formula: on-center = (mature width × density %); shrubs = run length ÷ on-center (hedge) or area ÷ on-center² × rows (mass)How to use this calculator

Enter the mature shrub width for your species — the calculator converts it to an on-center spacing.

Set density to 60–70% for a solid hedge that closes in one season, or 100% for a loose naturalistic grouping.

Switch to mass-bed mode for staggered border plantings and set the row count.

Frequently asked questions

How do I calculate how many shrubs I need for a hedge?

Divide the hedge length by the on-center spacing (mature width × density percentage). For a solid hedge use 60–70% of mature width.

How far apart should I plant shrubs?

Space shrubs at 60–70% of their mature width for a solid hedge, or at full mature width for a loose foundation grouping that keeps individual form.

How many boxwoods do I need for a hedge?

A 40 ft boxwood hedge with 36 in mature width at 70% density needs roughly 19 shrubs spaced about 2.1 ft on center.

How much does it cost to plant a hedge?

Installed shrub cost typically runs $35–$65 per shrub for #1 containers; multiply the shrub count by your per-shrub price for a total estimate.
