Three practical guides for a project that starts with the right questions.
Guide 01
Know the space you’re covering.
Before calculating, make a clear record of the area.
Sketch the boundaries.
Identify the floor or wall you plan to tile. Note alcoves, steps, openings, columns and separate sections rather than relying on one overall rectangle.
Record measurements and units.
Keep a consistent unit and label each dimension. For an irregular shape, divide it into measurable sections or review the captured floor polygon.
Confirm what is included.
Decide how the finish will meet doorways, cabinets and other boundaries. Record areas to add or subtract so the quantity can be checked later.
Check the result on site.
Compare a scan with physical measurements. Look for missing corners or surfaces. Correct the plan before using it to order materials.
Calculate tile quantities. Then calculate purchase quantities in cartons.
Convert the checked tiling area into a tile quantity, add extra tiles for cuts and breakage, and calculate the number of full cartons of tiles to purchase.
Choose the actual product.
Record its size and manufacturer-stated pack coverage. Convert dimensions into the same unit used for the area before a hand calculation.
Look at the layout.
Check the starting point, pattern and cuts at the edges. Narrow strips, obstacles and matching requirements can influence the order.
Set the tile loss percentage based on the layout and cutting requirements.
Include extra tiles for cutting, handling damage and future repairs. Choose a suitable tile loss percentage with your supplier or installer. An example percentage is not a fixed rule.
Calculate the number of full cartons of tiles to purchase.
First add the extra tiles needed for cutting and breakage to the base tile quantity. Divide the total by the number of tiles in each carton. If the result is not a whole number, use the next larger whole number: for example, 9.25 means purchasing 10 full cartons of tiles. Record both the tile quantity needed and the quantity included in the purchased cartons of tiles.
Match mortar, adhesive, grout and other products to the planned installation. Use current product instructions and the installer’s assessment for quantities and suitability.
Check the price basis.
Confirm pack sizes, currency and whether a price is per item, box, bag or area. Review shipping and other charges separately.
Review the scope.
Identify tools, rentals, preparation and services that may sit outside the material estimate. Keep notes so the figure can be understood later.
Recheck when the plan changes.
A different tile, room boundary or layout can affect quantities and costs. Update the purchase list before ordering, and retain the final assumptions with your project.
