Exposed edges
Measure the tile edge; 1/4 in = 6.35 mm, 3/8 in = 9.5 mm.

Buy one spare stick if the trim is special-order; a bad mitre on the last piece stalls the job.

How this calculator works
Stick length. Schluter sells its JOLLY, RONDEC and QUADEC profiles in 2.5 m lengths, listed in the US as 8' 2-1/2". The calculator uses 2.5 m = 98.43 in so it never counts on more metal than the stick has. Most big-box trims are 8 ft (96 in).
Packing the cuts. A run longer than one stick takes full sticks plus a remainder. The remainders and short runs are sorted longest first and each is cut from the first stick with room left, allowing 1/16 in of saw kerf per cut. That is how you would plan it on the bench, and it keeps offcut low.
Profile height. Schluter sizes its profiles by the tile thickness, so the finished edge sits flush with the tile face. The calculator picks the smallest of the common heights (6, 8, 10 and 12.5 mm) that is at least your tile's thickness.
Worked example. A backsplash with two 30 in sides and a 72 in top edge is 132 in of trim. On 2.5 m sticks the 72 in piece takes one stick (26.4 in left), and both 30 in pieces come out of a second stick. That is 2 sticks, 3 cuts and about 65 in of offcut. For 9 mm tile, buy the 10 mm profile.
Frequently asked questions
How much tile edge trim do I need?
Measure every exposed tile edge as a separate run, then fit the runs onto the stick length you are buying. A backsplash with two 30 in sides and a 72 in top needs 132 in, which is 2 sticks of 2.5 m Schluter profile.
How long is a stick of Schluter trim?
Schluter's JOLLY, RONDEC and QUADEC profiles come in 2.5 m lengths, sold in the US as 8' 2-1/2". Many generic PVC and aluminium trims are 8 ft.
What size tile edge trim do I need?
Match the profile height to the tile thickness. For 9 mm tile use a 10 mm profile; for 6 mm tile a 6 mm profile. Measure the tile itself, not the listing, because thickness varies between makers.
Can I join two pieces of trim on one edge?
Yes. Butt the ends tight on a long run, or use the maker's connector piece. Plan the joint where it is least visible, such as behind an appliance or at a cabinet line.
