Trees per Acre — Row × Tree Spacing

What this calculator determines

Trees per acre from row and in-row spacing, plus optional total trees for a block by acres or rectangular dimensions.

Formula or calculation method

Trees per acre

trees per acre = 43,560 ÷ (in-row spacing × row spacing)

43,560 is square feet per acre.

Spacing with acres

total trees = trees per acre × acres

Rectangular block

• rows in block = floor(block width ÷ row spacing)
• trees per row = floor(block length ÷ in-row spacing)
• block tree capacity = rows × trees per row

The block mode uses integer counts (floored) and does not add partial rows.

Definitions of inputs

• In-row spacing — Distance between trees within a row, in feet.
• Row spacing — Distance between tree rows, in feet.
• Acres — Total planted area when using the acres mode.
• Block length / width — Rectangular block dimensions in feet for capacity mode.

Worked example

Example only — not a recommendation.

12 ft between rows and 4 ft in-row:

• Trees per acre = 43,560 ÷ (12 × 4) = 43,560 ÷ 48 = 908 trees/acre
• On 5 acres: 908 × 5 = 4,540 trees

How to interpret the result

Compare density options against equipment access, rootstock vigor, and training system. Confirm final layout with a planting plan. Headlands and irregular edges will reduce actual counts below the rectangular estimate.
