QuantityWise, for people who have to buy the right amount
A renovation calculator suite that turns room measurements into purchasable quantities of tile, paint, flooring, wallpaper, decking, drywall, and concrete.
- For
- DIY renovators and small building projects
- Worth noticing
- Waste factors vary by laying pattern, including roughly 18–20% for herringbone versus about 8% for a straight run.
Field notes
The suite models ordering as a construction problem rather than a simple area calculation. Its examples distinguish herringbone waste from straight-run waste, separate paint coverage by coat, and round results into tins, packs, boxes, or bags. The site also says its calculator pages expose formulas and assumptions, including grout quantities derived from tile geometry. The extract does not show the individual input screens or a completed result.
