How to calculate square footage for sod
Sod square footage is simply the area of ground you want to cover in grass, measured in square feet. Because sod is a flat layer of living turf, there is no depth or volume to work out — the calculation is area = length × width, and nothing more. That makes it one of the easiest landscaping materials to estimate, as long as you measure the right space and remember to leave out everything that isn't going to be lawn.
Start by walking the yard and sketching it from above. Draw each open stretch of grass as its own rectangle, measure the length and width of each in feet, and multiply them. Add the rectangles together, then subtract the footprint of flower beds, the driveway, walkways, and the house or shed. What's left is your net sod area. This is the same approach you'd use for a full lawn estimate, just aimed at the sections you're laying turf on.
From square feet to pallets and slabs
Once you have the net area, you can order sod in whichever unit your supplier uses. Priced by the square foot, you buy the exact area plus a waste allowance. By the slab, divide your area by about 2.67 sq ft, the coverage of a standard 16-by-24-inch piece. By the pallet, divide by roughly 450 sq ft — the typical coverage of a full pallet, though it can run anywhere from 400 to 500 depending on the grower and slab size.
Always add 5–10% before you convert. Curved beds, angled walkways, and rounded corners force you to trim pieces, and the offcuts rarely fit anywhere else. A little extra also covers the odd broken or dried-out slab. Unlike a mulch order, where surplus just makes a thicker layer, leftover sod has a short shelf life, so aim for a modest cushion rather than a big one.
Ordering and laying fresh sod
Sod is a perishable, living product. It's cut to order at the farm and starts declining the moment it's stacked on the pallet, so time your delivery for the day you plan to install. On a warm day, unwatered sod can yellow within 24 hours, and heat-stressed turf may not root properly once it's down. Prep the soil, measure and order in one go, and have help ready so the whole yard goes down quickly.
