About landscaping calculations
Landscaping runs on area and volume. How much sod or turf covers a lawn, how much topsoil or gravel fills a bed to a given depth, how many edging units run around a border — every one of these is the same kind of measurement problem, where a few site dimensions decide how much material to order and how much it costs.
The landscaping tools here handle that arithmetic and the waste allowance that goes with it, showing the working so you can see how the lawn's shape and your piece size change the count. They take dimensions in feet or metres and convert as needed, because materials arrive in both imperial and metric units depending on the supplier.
Using the results
Treat the quantities as shopping figures, not guarantees. Living materials like sod and turf are perishable, so order them to arrive the day you lay them, and confirm the coverage per pallet or per roll with your supplier — it varies by grower. The number here tells you how much to buy; ground preparation, watering and timing are the parts that decide whether the lawn takes, so plan those alongside the order.
