Vines Per Acre Calculator
Vines Per Acre Calculator
Our vines per acre calculator takes inputs like row spacing, vine spacing, and the total land area to maximize vineyard efficiency and grape production potential.
Vines Per Acre Formula
The formula for calculating vines per acre is:
Vines per Acre = (43,560 ÷ Row Spacing) × (1 ÷ Vine Spacing)Where:
- 43,560 is the number of square feet in one acre
- Row Spacing is measured in feet between rows
- Vine Spacing is measured in feet between vines within a row
With 8-foot row spacing and 6-foot vine spacing:
Vines per Acre = (43,560 ÷ 8) × (1 ÷ 6) = 908.33 vinesVines Per Acre Chart

How to Calculate how many vines per acre?
- Choose Your Spacing: Row Spacing: 8 feet, Vine Spacing: 6 feet
- Calculate Rows Per Acre: Take 43,560 and divide by row spacing, 43,560 ÷ 8 = 5,445 feet of row per acre
- Calculate Vines Per Row: Take 1 and divide by vine spacing, 1 ÷ 6 = 0.167 vines per foot of row
- Calculate Total Vines: Multiply steps 2 and 3, 5,445 × 0.167 = 908.3 vines per acre
In high-density planting scenarios, using 6-foot row spacing and 4-foot vine spacing yields approximately 1,815 vines per acre. This configuration maximizes land use but requires careful management of canopy and precise equipment operation.
Medium-density planting represents a balanced approach, with 8-foot row spacing and 6-foot vine spacing resulting in 908 vines per acre. This configuration offers good accessibility for equipment while maintaining efficient land use.
Low-density planting utilizes 10-foot row spacing and 8-foot vine spacing, resulting in 545 vines per acre. This spacing is ideal for vigorous varieties or regions with high rainfall, as it provides excellent air circulation and reduces disease pressure.
How Many Grape Vines to Plant Per Acre?
Most commercial vineyards plant between 600 to 1,200 vines per acre. For example, a moderate-density planting might use 8-foot row spacing with 6-foot vine spacing, resulting in approximately 908 vines per acre.
What is the Spacing for Vines?
Row spacing typically ranges from 6 to 12 feet, with most commercial vineyards settling on 8 to 10 feet for optimal equipment access. Vine spacing within rows usually varies from 4 to 8 feet, depending on the grape variety and training system. End post spacing generally requires 6 to 8 feet from the last vine to ensure proper support and tension for the trellis system.
