Projects
Plan by project
Start from the job rather than the tool. Each project groups the measurements, materials and calculators it needs.
Flooring & Tile
Measure a room, choose a layout and work out how much material to order before you get to the checkout.
- Tile a floor or wall
- Lay laminate or vinyl
- Plan an underlayment
Painting
Estimate coverage for walls, ceilings and trim, and understand why a second coat changes the numbers.
- Paint a room
- Measure wall area
- Subtract doors and windows
Walls & Drywall
Plan sheet layouts, framing spacing and finishing materials for new walls or a room repair.
- Board a stud wall
- Patch and finish
- Frame a partition
Concrete & Masonry
Convert slab and masonry measurements into the volume and quantities you need to order.
- Pour a slab
- Set fence posts
- Lay a block wall
Decks & Fencing
Size boards, joists, posts and panels so your material list matches the structure you drew.
- Build a deck
- Run a fence line
- Replace decking boards
Garden & Landscape
Work out bulk materials by volume — mulch, topsoil, gravel and edging — instead of guessing by the bag.
- Fill raised beds
- Spread mulch
- Lay a gravel path
Our approach
Measure once. Plan with confidence.
Make It Fit helps homeowners and DIYers estimate quantities, reduce waste, and understand the calculations behind their projects — before the trip to the store.
Estimate quantities
Turn the measurements you already have into the number of tiles, packs, sheets or bags to order.
Reduce waste
Sensible allowances for cuts and offcuts, so you are not returning half a pallet or making a second trip.
Understand the maths
Every tool shows the calculation behind the result, so you can check it against your own numbers.
