- Usable width: Wu = W - 2m where W is board width and m is edge margin.
- Usable height: Hu = H - 2m where H is board height.
- Auto grid columns: c = ceil( sqrt( n * (Wu / Hu) ) ) and r = ceil(n / c).
- Even spacing: sx = Wu / (c - 1) (if c>1) and sy = Hu / (r - 1) (if r>1).
- Coordinates: x = m + col * sx, y = m + row * sy starting at row/col zero.
- Hole snapping: snap(v) = m + round((v - m)/p) * p where p is hole pitch.
- Measure your pegboard width and height using one unit system.
- Enter the hole pitch from your panel’s hole spacing.
- Set an edge margin to keep hooks off the border.
- Choose a layout mode: auto grid usually fits best.
- Optional: set minimum gaps for bulky garden tools.
- Click Calculate Spacing and review the coordinate table.
- Turn on snapping if you want hole-aligned coordinates.

Workshop-ready layout for garden storage
Pegboard walls help gardeners keep hand tools visible, dry, and easy to grab. This calculator converts your board measurements into a repeatable hook map, so you can reorganize seasonally without guessing. It is designed for shed and garage boards where spacing must respect the frame, the hole pattern, and bulky tool handles. Many gardeners use the coordinate table to create zones for pruning, planting, and irrigation accessories, keeping heavier items lower and tools separated. Re-running the calculator after a tool upgrade keeps spacing consistent across boards.
Inputs that match real pegboard constraints
Enter board width, board height, edge margin, hole pitch, and total hooks. The edge margin reserves a strong border and prevents hooks landing too close to mounting hardware. Hole pitch represents the center-to-center distance between holes, commonly 1 inch or 25 mm on many panels, and it drives the optional snapping feature.
Grid modes for different tool collections
Auto grid recommends rows and columns using the usable width-to-height ratio, which helps long boards avoid cramped columns. Fixed grid is useful when you already planned a pattern, such as 4 columns for trowels, pruners, gloves, and twine. Single row or single column supports narrow strips for labels, seed packets, or hose nozzles.
Spacing results you can mark and verify
After submission, the result panel shows the suggested grid, the horizontal and vertical spacing, and a coordinate table for each hook position. X and Y are measured from the top-left corner, starting at the edge margin. If you enable snapping, coordinates are rounded to the nearest hole centers, reducing layout drift during installation.
Exports for planning, printing, and sharing
CSV export captures your latest run, including board values, spacing, and the full coordinate list for shop notes or spreadsheet filtering. PDF export produces a print-friendly table that can be carried to the shed. Use minimum gap warnings as a safety check for bulky garden tools, then adjust hook count or grid size for better clearance.
Frequently Asked Questions
1) What does edge margin actually do?
It reserves space around the perimeter so hooks avoid weak edges, frames, and mounting bolts. The usable area is the board size minus twice the margin on each side.
2) Should I turn on snapping to hole centers?
Yes for standard pegboard. Snapping rounds the calculated coordinates to the nearest hole centers using the pitch, which makes marking and installation faster and more accurate.
3) Why does auto grid change rows and columns?
Auto grid uses the usable width-to-height ratio to balance the layout. Wide boards tend to get more columns, while tall boards tend to get more rows for the same hook count.
4) What if the minimum gap warnings appear?
Warnings mean the computed spacing is tighter than your preferred clearance. Reduce hooks, choose a larger board, or use a smaller fixed grid so handles and bulky tools do not collide.
5) How are X and Y measured on the board?
Coordinates start at the top-left corner. The first hook position begins at the edge margin, then spacing is applied across columns and down rows.
6) Why does the CSV download require a recent calculation?
