Tiling Tips
Even small joint changes can alter total tile counts and perimeter cut widths across large areas.
Centered layouts typically avoid tiny sliver cuts that are hard to install and less durable.
Wider joints can absorb tile variation, while narrow joints require stricter flatness and calibration.

The calculator builds grout-aware tile modules from your tile dimensions and joint width, then maps those modules across the target area to estimate quantities and perimeter cut exposure.
Module Width = Tile Width + Grout JointTiles Across = (Surface Width + Joint) / Module WidthTotal Tiles = Horizontal Count x Vertical CountShare it with anyone planning tile installs, backsplashes, or floor renovations.
