Lawn size

A common US slab is 24 × 16 in (about 2.67 ft²). Large rolls are much longer.

Often 400–500 ft²; ask your supplier.

Curves, edges and beds mean trimming. 5–10% is a common allowance.

Result

Pieces (slabs or rolls) needed

Order 591 pieces of sod to cover 1,575 ft², about 3.5 pallets.

Step-by-step solution

  1. Multiply the lawn's length by its width to get its area

    50×30=1,500 ft²

  2. Add 5% extra, because pieces get trimmed at edges and beds

    1,500×1+0.05=1,575 ft²

  3. Find the area of one piece: length times width, then divide by 144 to turn in² into ft²

    24×16144=2.666667 ft²

  4. Divide the area to order by the area of one piece, then round up so no gap is left

    1,5752.666667=590.625=round up → 591

  5. Divide the area to order by what one pallet covers to see how many pallets that is

    1,575450=3.5=round up → 4

What this calculator does

Find out how many pieces and pallets of sod to order for your lawn. Sod, also called turf, gives you a finished lawn in a day. But you buy it in pieces: small slabs, longer rolls, or whole pallets that each cover a set area. To order the right amount, you need three things. You need the area of the lawn and the size of each piece. You also need a little extra for trimming around every curved edge, path and flower bed.

Enter the lawn's length and width, or an area you already know. The calculator adds a little extra for waste. Then it divides by the area of one piece and by what one pallet covers. That shows you how many pieces you need and how many pallets that adds up to.

Where it's used

Why this math matters outside the classroom:

  • New lawns. A 40 × 25 ft lawn is 1,000 ft², and a 5% allowance brings the order to 1,050 ft².
  • Piece counts. Pieces 16 × 24 in cover 384 in², or 2⅔ ft², so 1,050 ft² takes 394 pieces.
  • Pallets. If a supplier's pallet covers 450 ft², then 1,050 ft² is 2.33 pallets, so the buyer orders 3 or adds loose pieces.
  • Odd shapes. Landscapers split an L-shaped yard into two rectangles and add their areas before ordering sod.
  • Turf rolls. Groundskeepers laying big rolls on a sports field divide the field area by the area of one roll.

How to use it

  1. Choose US units (feet, inches, square feet) or metric units (meters, centimeters, square meters).
  2. Enter the lawn's length and width, or switch to entering a known total area.
  3. Enter the size of one sod piece or roll and how much area one pallet covers, from your supplier.
  4. Set the extra for cuts and waste. Then read the pieces and pallets to order.

What the inputs mean

Lawn area
Use this if you have already measured the lawn in sections and added them up.
Piece length
Sod comes in several formats. Small slabs of around 16 by 24 inches are common for laying by hand. Big rolls laid by machine can be 2 to 4 feet wide and tens of feet long. Measure a piece or ask the supplier.
Coverage per pallet
Pallet coverage varies by grower and grass type. Many US pallets cover somewhere around 400 to 500 ft², but use your supplier's figure.
Roll length
Many turf rolls cover about 1 m², for example 160 × 62.5 cm.
Extra for cuts and waste
Rectangular lawns with straight edges need little extra. Curved borders, many beds or trees, and odd corners mean more trimming. For those, raise the allowance.

Formula and method

lawn area = length × width
area to order = lawn area × (1 + allowance % ÷ 100)
piece area = piece length × piece width (÷ 144 for in² → ft², ÷ 10,000 for cm² → m²)
pieces = area to order ÷ piece area, rounded up
pallets = area to order ÷ coverage per pallet

The allowance is the extra percentage you add for waste. It's added to the lawn area first, so the piece count and the pallet count both include the extra. You enter piece sizes in inches or centimeters. So the calculator turns the piece area into square feet or square meters before dividing. There are 144 square inches in a square foot, and 10,000 square centimeters in a square meter.

The number of pieces is rounded up to a whole piece. The pallet figure is shown both exactly and rounded up. That's because some suppliers sell part pallets and others only full ones. Tiny computer rounding errors are cleaned up first, so an exact answer is never pushed up by one.

Worked example

A back lawn is 50 ft by 30 ft. The sod comes in 24 × 16 inch slabs, a pallet covers 450 ft², and you allow 5% for cuts.

  1. Lawn area: 50 × 30 = 1,500 ft².
  2. With 5% extra: 1,500 × 1.05 = 1,575 ft².
  3. One slab: 24 × 16 ÷ 144 = 2.6667 ft² (exactly 8/3).
  4. Pieces: 1,575 ÷ 2.6667 = 590.63, which rounds up to 591 slabs.
  5. Pallets: 1,575 ÷ 450 = 3.5 pallets, or 4 whole pallets.

Result: Order 591 slabs, covering 1,575 ft² (146.32 m²), which is 3.5 pallets.

Understanding the result

If your supplier only sells whole pallets, the whole-pallet figure is what you'll pay for. The spare pieces can patch thin spots later. If they sell part pallets or single pieces, order the exact piece count.

Sod spoils quickly, so lay it soon after delivery, ideally the same day. Have the ground ready before the pallets arrive, so none of it dries out while you work.

Assumptions and limitations

  • The lawn area is flat and measured as a rectangle or a known total.
  • All pieces are the same size, and the pallet coverage figure includes every piece on the pallet.
  • One percentage allowance covers trimming, edges and damaged pieces.
  • Irregular shapes aren't handled directly. Measure them in sections and enter the total area.
  • The calculator doesn't cover soil preparation, starter fertilizer or watering.
  • Pallet coverage and piece sizes vary widely between suppliers. The defaults are only examples.

Frequently asked questions

How much does one pallet of sod cover?

It depends on the grower and the format. Many pallets in the US cover roughly 400 to 500 ft². Divide your area to order by your supplier's figure to see how many pallets you need.

How many square feet is one piece of sod?

A 24 by 16 inch slab is 384 square inches, which is 2.67 ft². So about 375 slabs cover 1,000 ft². Larger rolls cover much more each, so always check the size of the product you're buying.

How much extra sod should I order?

About 5% is often enough for a simple rectangle. For lawns with curves, many beds or trees, 10% or a little more is safer. Leftover pieces are handy for repairing patches.

Is sod or seed better for a new lawn?

Sod gives an instant, usable lawn, and it stops soil washing away right from the start. But it costs a lot more per square foot. Seed is cheaper and offers more grass choices, but it takes weeks to grow in. The grass seed calculator works out the amount of seed for the same area.

How this calculator is checked

Method: Rectangle area with a percentage allowance, divided by piece area and pallet coverage; counts rounded up after removing floating-point noise. The calculation is covered by automated tests with known reference values and edge cases. Last updated 2026-10-18. Found a problem? Tell us.
