Flooring and tile calculator for Shopify
In short: Trimsize lets flooring and tile stores sell by the room on Shopify. Customers enter the room's width and length and choose a laying pattern; Trimsize adds that pattern's waste, rounds up to whole boxes and prices them at your rate per m² or sq ft, with underlay and edge trim priced from the room, and Shopify charges exactly that at checkout.
What your customers get
- Their room, not a box count: they enter the width and length they measured.
- The laying pattern as a choice, straight, diagonal or herringbone, with its waste allowance included.
- Whole boxes, so they don't run short halfway through the floor.
- Underlay and trim priced from the room's area and perimeter, in the same price.
Priced the way you sell
Flooring is sold by the box, so the maths is: room area, plus the pattern's waste, divided by the box's coverage and rounded up. In the starter, a 4 × 3.5 m room of oak laminate at $14.95 per m² in boxes of 2.2 m² needs 7 boxes laid straight ($230.23) or 8 in herringbone ($263.12). With underlay and edge trim, the straight-laid room is $369.23. The flooring by the box guide has examples in feet and for tiles.
Each box size needs its own product, since the box maths lives in the product's formula. Set the waste per pattern to the allowance you recommend in store.
From order to the warehouse
Each line says the room size, pattern, floor and extras, so the box count you pick is the one the customer paid for. On Pro, the production queue totals the room area ordered in each floor across open orders, and quotes as draft orders cover whole-house jobs.
Questions
Can customers enter several rooms?
Each room is its own cart line: customers add the product once per room, with that room's size and pattern, and each line is rounded to whole boxes.
Does it work for tiles as well as flooring?
Yes. Tiles are sold by the box the same way: set the box's coverage in the formula and the waste allowance on each pattern.
Can I sell in square feet?
Yes. Set the room size in feet, the rate per square foot and the box coverage in square feet.
