SoftTiles Oak Wood Grain Side Borders
To calculate the number of borders you need, look at your arrangement of tiles, for example a 10 ft. x 8 ft. area is 5 tiles x 4 tiles. Add the # of tiles for length and width together, and multiply that by 2. That will be the number of oak wood grain side borders needed to border the entire area. Subtract 8 (which will be corner pieces) and you will get the number of playmat edge borders you need.
10 ft. x 8 ft. area = 5 tiles x 4 tiles.
Add (5 + 4) to get 9. Multiply by 2 to get 18.
Subtract 8 pieces for corners, which leaves you 10 side borders.
Total borders you need:
10 side wood borders
4 wood corner sets
