How to Measure Diagonal Floor Tile

Most tile floors are squared to the walls of the room.

Measuring floor area for the installation of tile is simple. Most tile designs are squared to the room, meaning that the measurements should be the actual dimensions of the room. Measuring the floor to identify how much tile is necessary for an angled-tile pattern can be done using the standard dimensions of the room while remaining accurate. The square footage of a room remains the same regardless of the angle of the tile. Always add a little extra to the measurement to have additional tiles on hand in case of damaged tiles.

Things You'll Need

• Measuring tape
• Calculator
• Tape

Instructions

1. Divide the room into square and triangle sections visually. Stretch tape along the floor for a reference point for each section.

2. Measure the length and width of each section. Triangle sections will have a 90-degree corner. Measure the length and width of the edges of the 90 degree corner.

3. Multiply each section's length by the width to obtain each individual area. Divide the area of triangle sections by two.

4. Add each section's area together to obtain a total square footage for the room.

5. Multiple the total area by 1.10 to add 10 percent to the total for excess material.

6. Divide the total of the calculations by the square footage of one tile to identify how many tiles are necessary for the room. The square footage of the individual tile or the case of tiles is listed on the case.

Tips & Warnings

• Angled patterns will require substantially more cutting than a straight pattern. You may want to allow yourself 15 to 20 percent extra material to allow for mistakes made during the cutting. If you are measuring an existing tile floor, count the number of tiles present and multiply the number by the height and width of one tile.
