Read the two spacing ranges correctly
The linked guide gives a range, not a single required number. Within-row sowing distance is 2–3 inches; row-to-row distance is 18–24 inches. Treat these as the bounds you choose within, and write down the value you selected so the plan can be checked later.
The in-row number describes where seeds are sown. It is not a promise about how many plants establish, and it is not a mature-plant spacing rule. Count seed positions separately from actual established plants, as the source context directs.
- Record the chosen in-row distance as a value between 2 and 3 inches.
- Record the chosen row-to-row distance as a value between 18 and 24 inches.
- Label the scenario the values apply to, such as one raised bed or one open-garden row.

Choose one labeled scenario and mark it
For a clearly labeled scenario, this guide uses 3-inch centers within the row. That is the upper end of the 2–3 inch range, chosen for this example only; it is not a claim that 3 inches suits every garden. The row-to-row figure must still be chosen separately from the 18–24 inch range.
Marking is geometrical: place centers at the chosen interval along the measured row, keeping the end margins you decide. A single marked row is one line of sowing positions, not an entire garden layout. Access paths, support structures, adjacent rows and mature plant habit all need their own decisions, and this brief supplies no distances for them.
- Measure the actual row length before marking anything.
- Mark the first and last centers using your chosen end margins.
- Space intermediate centers at the selected in-row interval.
- Keep the row-to-row choice separate from the in-row marks.

Worked example: one 96-inch row
The verified example is one measured 96-inch row with 3-inch centers and 1.5-inch margins at both ends. The first center falls at 1.5 inches and the last at 94.5 inches, giving 32 sowing positions. The counted item is sowing positions, not established plants.
This example is a geometrical count for one row. It does not set a row-to-row distance, describe a whole bed layout, or predict germination. The linked row calculator can count this exact length, center interval and both end margins in inches or centimeters.
- Enter 96 inches as the row length.
- Enter 3 inches as the center interval.
- Enter 1.5 inches for both end margins.
- Check that the result reads 32 sowing positions.

Keep sowing, thinning and established plants separate
Sowing positions are where seeds go. Thinning and the eventual number of established plants are later questions, and the source context explicitly separates seed positions from actual established plants. Do not relabel a sowing-position count as a plant count.
When you revise the plan, change one value at a time and recheck the count. If you move to a different in-row distance inside the 2–3 inch range, the position count changes even though the row length does not.
- Label the calculator result as sowing positions.
- Note any later thinning decision separately from the sowing count.
- Recheck the count whenever the interval or margins change.

Check your measured example
One measured 96-inch row, with selected 3-inch centers and 1.5-inch margins at both ends. Count 32 sowing positions.
Reference and growing system: USU describes beans sown 2–3 inches apart in rows 18–24 inches apart. Count seed positions separately from actual established plants.
| Quantity | Calculated result |
|---|---|
| Usable row length (in) | 96 |
| Selected center spacing (in) | 3 |
| Margin at each row end (in) | 1.5 |
| Positions in this row | 32 |
| First center from row start (in) | 1.5 |
| Last center from row start (in) | 94.5 |
| What is being counted | sowing positions |
The worked example uses a 96-inch row, 3-inch centers and 1.5-inch margins at both ends. Centers run from 1.5 to 94.5 inches, producing 32 sowing positions. It is a geometrical count for one labeled row; it does not set row-to-row spacing, describe a bed layout, or predict how many plants establish.

Your before-you-plant checklist
- Chosen in-row distance is between 2 and 3 inches and written down.
- Chosen row-to-row distance is between 18 and 24 inches and written down.
- The scenario is labeled, such as one raised bed or one open-garden row.
- The count is labeled sowing positions, not established plants.
- The 96-inch example is treated as one row, not a full garden layout.
Questions that come up while planning
How far apart should bean seeds be sown?
USU describes beans sown 2–3 inches apart in rows 18–24 inches apart. Choose a value within each range and record it for your scenario.
Does 32 sowing positions mean 32 bean plants?
No. The example counts sowing positions. Count seed positions separately from actual established plants, as the source context states.
Can I use the 96-inch example as my whole garden layout?
No. It is one measured row with 3-inch centers and 1.5-inch end margins. Row-to-row distance, access, supports and adjacent rows must be chosen separately.
