Vegetable Garden Row Spacing Chart & Calculator
Plan your garden rows before you plant. This free vegetable garden row spacing calculator tells you how many rows fit across your bed, how many plants fit in each row, and your total plant count — or use the built-in vegetable garden row spacing chart for quick general guidance.

How to use this calculator
Start by picking a crop preset — it fills in typical between-row and in-row spacings for that vegetable, and you can fine-tune either number. Or choose Custom and enter your own. Then enter your bed's width and length in feet.
Results update instantly as you change anything: the number of rows that fit across the width, how many plants fit in each row, and your total plant count. Use the numbers to plan seedling purchases or to lay out rows with string before you dig.
How it works
The calculator converts your bed to inches and applies three steps. Rows across the width: rows = floor(bed width in inches ÷ row spacing in inches). We round down because a partial row does not really fit — the first row starts about half a row-spacing in from the bed edge, so every row keeps its full spacing on both sides. Plants per row: floor(bed length in inches ÷ in-row spacing in inches), rounded down for the same reason. Total plants: rows × plants per row.
For example, a 4 × 8 ft bed with 12-inch row spacing holds floor(48 ÷ 12) = 4 rows. With 6-inch in-row spacing, each row holds floor(96 ÷ 6) = 16 plants, for 4 × 16 = 64 plants total. These are estimates — actual layouts vary with plant variety, edge margins, and growing method.
Vegetable garden row spacing chart
The table below lists typical spacing ranges for common vegetables. Treat these as general guidance — your seed packet or plant tag has the final word for the variety you are growing.
| Crop | Between rows (in) | In-row spacing (in) |
|---|---|---|
| Tomatoes | 24–36 | 18–24 |
| Peppers | 18–24 | 12–18 |
| Carrots | 12–16 | 2–4 |
| Lettuce | 12–18 | 6–12 |
| Bush beans | 18 | 2–4 |
| Corn | 30–36 | 9–12 |
General guidance only — spacing needs vary by variety, climate and growing method. Always check your seed packet.
Frequently asked questions
How much space should I leave between garden rows?
As a rule of thumb, 12 inches between rows works for small crops like carrots and lettuce, 18 to 24 inches for peppers and beans, and 24 to 36 inches for tomatoes and corn. Wider rows make it easier to walk, water and harvest; tighter rows squeeze more plants into small beds but need richer soil and more careful watering. The spacing chart on this page lists typical ranges for common vegetables — always check your seed packet, since varieties differ.
How do you calculate how many rows fit in a garden bed?
Convert the bed width to inches and divide by the row spacing in inches, then round down to the nearest whole row: rows = floor(bed width in inches / row spacing in inches). Rounding down matters because a partial row does not really fit. The first row starts about half a row-spacing in from the bed edge, so every row gets its full spacing on both sides. For example, a 4-foot (48-inch) wide bed with 12-inch row spacing holds floor(48 / 12) = 4 rows.
How many plants fit in a 4x8 foot raised bed?
It depends on the crop. With 12-inch row spacing, a 4-foot-wide bed holds 4 rows. At 6-inch in-row spacing, each 8-foot row holds floor(96 / 6) = 16 plants, for 4 x 16 = 64 plants total. The same bed planted with tomatoes at 30-inch row spacing and 24-inch in-row spacing holds only 1 row of 4 plants — big crops need big space.
Do tomatoes and corn really need wider row spacing?
Yes. Tomatoes and corn are large, hungry plants that shade their neighbors — 24 to 36 inches between rows (30 to 36 for corn) keeps air flowing, lets you reach every plant for staking and harvest, and leaves room for the root systems to feed. Small crops like carrots, radishes and salad greens thrive on 12 to 16 inches between rows.
Is row spacing measured from plant to plant or row to row?
Row spacing is measured center-to-center between rows — the distance from one row's center line to the next row's center line. In-row spacing is the distance between plants within the same row, measured stem to stem. Both numbers in this calculator are in inches, and the calculator assumes the first row starts half a row-spacing in from the bed edge.
