Stage 1: plan and order your materials
Start by measuring the area in square feet, length times width for each section, and sketching an awkward shape as a set of simple rectangles you can add up. Then add a waste allowance on top — usually around ten to fifteen percent — because you will trim edges, match the pile direction across pieces, and cut around curves and obstacles. Turf comes in fixed-width rolls, so planning the layout to run the pile the same way with the fewest seams saves both material and visible joins.
Once you have your area, order three things together: the turf itself, the crushed-rock base that goes underneath, and the infill that gets brushed in at the end. The material calculator turns your square footage and a spread rate into the tons of base and the pounds and bags of infill you need, so you are not guessing at the counter. Order the base and infill grades your turf supplier recommends, and buy the seaming tape, adhesive, and edge fasteners at the same time so the job does not stall halfway.
It helps to price the project before you commit to doing it yourself. The cost calculator shows a low-to-high installed range next to a materials-only figure, so you can see what the labor is worth on your particular yard. If the saving looks thin against the effort and risk, that is useful to know before the turf is delivered.
