Most Trident tiles are sold by the box, but we also show a price per square metre. That makes it easier to compare ranges — a £40/m² tile is clearly dearer than a £28/m² tile, even if the boxes cover different areas.
You always pay for whole boxes. The per m² figure is a guide for comparison, not a pay-by-the-slice rate.
The short version
- We take the box price and the m² covered by one box
- We divide box price ÷ m² per box
- We round that rate to the nearest whole pound per m²
- We show that rounded figure as £X / m² on cards and product pages
- At checkout you pay: number of boxes × box price
A worked example
Imagine a box costs £48.00 and covers 1.44 m².
- £48.00 ÷ 1.44 m² = £33.33 per m²
- Rounded to the nearest pound = £33 / m²
- That is the figure you see on the website
The product page calculator then works in boxes. If you need 8 m² with 10% wastage, you need 8.8 m² of coverage. 8.8 ÷ 1.44 = 6.11, which rounds up to 7 boxes. Your total is 7 × the box price — not 8.8 × £33.
Your total will rarely equal “m² typed in × price per m²” exactly. That is normal: we round the display rate, and we always round up to whole boxes.
Trident tip
Why totals can look “off”
- Per m² is rounded to the nearest £ for clear comparison
- You buy whole boxes only — leftover coverage in the last box is still paid for
- The optional 10% wastage toggle increases the area before boxes are calculated
Tiles priced per unit instead
Some products — especially Kit Kat strips and similar linear pieces — are sold per unit, not by the box and m². Those show a / unit price and a quantity picker instead of the m² calculator.
