Horse Bedding Calculator

Enter your stall area and desired bedding depth.

How it is calculated

The tool assumes one bag of shavings covers 35 square feet at a depth of 1 inch, so a bag provides 35 cubic-foot-inches of coverage. The formula is bags = ceil(A × D ÷ 35), where A is the stall floor area in square feet and D is the bedding depth in inches. The result is always rounded up to a whole bag, because you cannot buy a fraction of one. Both inputs must be greater than zero. Depth accepts decimals such as 3.5. The 35 sq ft figure is a fixed assumption; real bags differ by brand and by how much they fluff up, so check the coverage printed on your bag.

Worked example

A 12 ft × 12 ft stall has A = 144 sq ft, and you want D = 4 inches of bedding. Multiply: 144 × 4 = 576. Divide by the bag coverage: 576 ÷ 35 = 16.46. Round up to the next whole bag. Result: 17 bags, shown with the inputs 144 sq ft and 4.0 in.

Common mistakes

  • Entering the area in square metres or the depth in centimetres. The tool expects square feet and inches, so a 13 m² stall must be converted to about 140 sq ft first.
  • Typing the stall's length instead of its area. A 12 ft stall is 144 sq ft, not 12.
  • Ordering for the first fill only. Daily mucking removes shavings, so the figure is the amount for a full initial bed, not for weekly top-ups.
  • Assuming every bag covers 35 sq ft at 1 inch. Compressed bags of different brands expand differently, so a bag labelled with a different coverage will change the count.
  • Rounding down to save money. The tool rounds up on purpose; a thin bed lets urine reach the floor.

About this calculator

Stall bedding — most commonly wood shavings — needs to be deep enough to absorb urine, cushion the horse's legs and joints, and encourage the horse to lie down comfortably, with most stable managers targeting 4 to 6 inches of compressed depth over the full stall floor. Buying too little means constant top-ups and thin spots that let urine reach the floor; buying too much wastes money and storage space.

Because shavings are sold in compressed bags of a known volume, the amount needed is simply the stall's floor area multiplied by the target depth, converted to the coverage a standard bag provides. Stall area and the bedding depth you want become a bag count, the same arithmetic barn managers do when they order shavings or pellets by the pallet.

    Bags are worked out for the first fill, so the figure is higher than what you buy on a normal week. A 144 sq ft stall at 4 inches deep needs 17 bags. After that you usually remove only the soiled parts and top up, which takes far fewer bags, though how many depends on the horse and stall. How deep do you keep your stalls, and does it change in winter?
