Estimate seed spacing, seed count, rows, seeds per row, and extra seed needed for garden beds, raised beds, planting rows, vegetable gardens, flowers, herbs, and field-style planting areas.
Garden bed mode:
The calculator uses bed size, edge buffer, seed spacing, and row spacing to estimate rows, holes, and total seeds.
Row mode:
The calculator estimates how many rows fit across the bed and how many seed positions fit in each row.
Known area mode:
The calculator uses total square footage and spacing values to estimate seed density and seed count.
Target seed count mode:
The calculator estimates approximate spacing from a target number of seeds in the available planting area.
A seed spacing calculator helps plan how many seeds to plant before sowing a garden bed, raised bed, row crop, flower bed, or planting area.
It can help estimate seed count, row layout, extra seed, seed density, thinning needs, and how many seed packets may be required for a planting project.
Your result shows estimated seeds needed, planting holes, rows, seeds per row, usable planting area, seed density, extra seed amount, germination-adjusted seed amount, and approximate spacing when using target seed count mode.
Convert seed spacing and row spacing from inches to feet. Then divide usable bed length by seed spacing and usable bed width by row spacing to estimate seeds per row and rows.
Seed spacing is the distance between seeds in the same row. Row spacing is the distance between each planting row.
Not every seed will sprout. A germination adjustment helps estimate how many seeds to sow so the final plant count is closer to your goal.
Seeds per hole is the number of seeds planted in one spot. Some gardeners plant multiple seeds per hole and thin weaker seedlings later.
No. This is an estimate. Actual seed spacing can vary based on crop variety, germination rate, thinning method, soil quality, seed age, moisture, sunlight, and planting style.
