Tile Leveling Clip Calculator

How to use the Tile Leveling Clip Calculator
- Enter the floor's length and width.
- Enter the tile size, with its length running along the floor's length.
- Check the clip spacing under More options against your leveling system's instructions.
- Read the clips to buy, and enter the pack size to get the packs.
How it is counted
columns = ⌈floor length ÷ tile length⌉ (the last one cut to fit)rows = ⌈floor width ÷ tile width⌉clips per edge = ⌈edge length ÷ clip spacing⌉clips = Σ clips per edge, over every edge two tiles shareto buy = ⌈clips × (1 + allowance)⌉Counting edges rather than dividing the floor area by a coverage figure means small rooms, cut rows and long planks come out right. A pack’s “covers about X sq ft” is worked out for one tile size and assumes a large floor.
Assumptions
The grid is laid straight, tile length along the floor’s length. An offset or brick pattern has the same joints shifted, so it takes about the same number of clips. Joint width is ignored, since a 1/16 or 1/8 in joint barely changes how many tiles fit. Leveling clips help keep adjacent tiles even while the adhesive sets; they do not make an uneven floor flat, so the floor still needs the preparation the tile and adhesive makers call for.
With your numbers
- Clips per shared edge = ⌈edge ÷ 8 in⌉: 3 on each long edge, 3 on each short edge
- Every edge two of the 30 tiles share, counted once = 147 clips
- To buy = ⌈147 × (1 + allowance)⌉ = 147
Quick reference
No allowance by default. The count is for a straight grid; an offset pattern needs about the same.

RUBI (maker of the Delta Level leveling system), "Mastering Levelling Clips: A Guide To Tile Installation", published 2025-02-10, updated 2025-03-20: "Position the clips approximately 6-8 inches apart along the edges of the tiles." https://www.rubi.com/en/blog/levelling-clips/. The upper end is used because QEP’s LASH sheet uses fewer: its Project Pack (S0622-00000) says 100 clips cover "approximately 25 sq. ft. … for 6" by 24" tile and 100 sq. ft. … for 24" by 24" tile", and the Vitrex LASH instructions (09.08.22) say "Slide two clips under the tile approx. 50mm from each end of the tile".
Used for
- Largest gap between tile leveling clips along a joint: 8 in, the upper end of RUBI’s 6 to 8 in.
Common questions about the Tile Leveling Clip Calculator
- How many tile leveling clips do I need for a floor?
- 147 for a 12 by 10 foot floor of 24 × 24 in tile, with clips 8 in apart. Each 24 in edge takes 3 clips, and the 30 tiles share 49 edges, so 49 × 3 = 147. Enter the pack size on the page to see how many packs that is.
- How many tile leveling clips do I need per tile?
- It depends on the tile size and how far apart the clips go, not on the floor area alone. A clip bridges the joint between two tiles, so each shared edge is counted once. On a large floor of 24 × 24 in tile with two clips per edge, each tile owns about two edges, so about four clips per tile. Long planks need more along their long sides than across their ends.
- How far apart should leveling clips be?
- Follow the instructions for your system. RUBI’s guide puts clips about 6 to 8 inches apart along the edges, and this page uses 8 in unless you change it. QEP’s LASH instructions instead place two clips on each side, about 50 mm from each end, and QEP’s pack says 100 clips cover about 100 sq ft of 24 × 24 in tile but only about 25 sq ft of 6 × 24 in plank.
- Do I need to buy as many wedges as clips?
- Only if you lay the whole floor at once. Clips break off and are used once; wedges and caps come off after the adhesive sets and are used again. Laying a floor over several days needs only enough wedges for one day’s tiles.
- Why are there no clips around the edge of the room?
- A clip holds two tiles level with each other, so it only goes where two tiles meet. The tiles along the walls have no neighbour on that side. Cut tiles at the far walls still share edges with the tiles next to them, and the page counts clips on those shorter edges too.
