How to choose a rack that fits
- Find your tile size. Use the tile height and width from the listing; our set pages show both in inches and mm.
- Find the rack length. Use the rack length on the listing, or measure your rack end to end.
- Check the rack’s stated tile limit. Many rack listings state the largest tile they hold (for example “fits tiles up to 1.5 in”).
- Run the size checker. Enter both numbers in the tile / rack size checker for a heuristic estimate.
- Measure if borderline. Lay one row of tiles on the rack before buying more; for oversized designer tiles, look at 20 in racks.
