Horseshoe Pit Size Calculator
Horseshoe pit fill in cu ft and cu yd from width, length, and depth.
What it does
A horseshoe pit is a box of loose fill, not just a patch of dirt. The right volume keeps shoes sticking instead of bouncing, and it stops the pit from turning into a mud hole after rain. Guessing the fill means extra trips to the yard.
The tool above multiplies pit width by length by depth. A full 36 by 72 in pit at 8 in deep needs 12.00 cu ft, which is 0.444 cu yd, with 24.00 cu ft for both pits. The metric match is 91 by 183 by 20 cm toward 0.333 m3 per pit.
NHPA rules frame the sizes: pits run 31 to 36 in wide and 43 to 72 in long inside 6 ft square boxes, stakes 40 ft apart. Four inches of substance is the minimum and 8 in is the recommended working depth.
Order by the court, not the pit. Two pits double the fill, and damp sand compacts, so a little extra beats a short load. Level the fill, water lightly, and turn it over through the season.
How to use
- Pick imperial (in, cu ft) or metric (cm, m3).
- Enter pit width, length, and fill depth.
- Read fill volume per pit first.
- Read yards or both pits next.
- Buy fill by the larger unit yards or bags.
- Level to depth and check stake lean.
Formula
- W
- Pit width, 31 to 36 in (79 to 92 cm).
- L
- Pit length, 43 to 72 in (109 to 183 cm).
- D
- Fill depth, 4 to 12 in (10 to 30 cm).
NHPA pit rules set width 31 to 36 in and length 43 to 72 in inside 6 ft square boxes, with stakes 40 ft apart. Fill depth runs 4 in minimum to about 8 in recommended. The tool multiplies the three sides, converts to yards by 27, and doubles for a two pit court.
Worked example
Example: full size 36 by 72 by 8 in pit
Imperial defaults: 36 by 72 by 8 in. These are also the default values, so the page opens on this answer.
- Pit: 36 in wide, 72 in long, 8 in of fill.
- Convert: 36/12 = 3.0 ft, 72/12 = 6.0 ft, 8/12 = 0.667 ft.
- Volume: 3.0 x 6.0 x 0.667 = 12.00 cu ft.
- Yards: 12.00 / 27 = 0.444 cu yd.
- Both pits: 12.00 x 2 = 24.00 cu ft.
- Tool shows 12.00 cu ft per pit, 0.444 cu yd per pit, 24.00 cu ft both pits.
- Metric match: 91 by 183 by 20 cm gives 0.333 m3 per pit, 0.666 m3 both.
Reference table
| Pit in | Cu ft | Cu yd |
|---|---|---|
| 31 x 43 x 4 | 3.09 | 0.114 |
| 36 x 48 x 6 | 6.00 | 0.222 |
| 36 x 72 x 8 | 12.00 | 0.444 |
Limits
- Fill volume only; excludes frames, stakes, and backstops.
- Ignores compaction and moisture settling.
- Assumes level pit bottoms and straight sides.
- Rules vary slightly by league and backyard custom.
Common mistakes
- Ordering one pit of fill for a two pit court.
- Using 4 in of fill where 8 in plays better.
- Mixing pit size with box size.
- Skipping drainage under clay.
- Forgetting stakes sit 40 ft apart, not pit to pit.

Quick checks. Answers sit tucked under each question.
36 by 48 by 6 in pit?
3.0 x 4.0 x 0.5 = 6.00 cu ft, which is 0.222 cu yd.
91 by 183 by 20 cm in metric?
0.91 x 1.83 x 0.20 = 0.333 m3 per pit, both pits 0.666 m3.
Questions
Fill for a full size pit?
Multiply width by length by depth in feet, then divide by 27 for yards. Here 3.0 x 6.0 x 0.667 = 12.00 cu ft, or 0.444 cu yd.
What are the official pit dimensions?
31 to 36 in wide and 43 to 72 in long, with stakes 40 ft apart center to center.
How deep should the fill be?
Four inches is the minimum with 8 in recommended, so deeper pits hold the shoe better and need more fill.
Sand or clay?
Clay, sand, dirt, or synthetic per NHPA rules. Sand drains fast; clay holds shape.
How much for a full court with two pits?
Double one pit: two full pits at 12.00 cu ft each need 24.00 cu ft.
Is the pit the same as the box?
No. The box is 6 ft square at each end, while the pit is the smaller fill area inside it.
