How many lengths will this room take?
Enter the room, or the run you measured, take the door openings out and add an allowance for offcuts. The answer is a number of 3 m lengths to order. It is an estimate for budgeting and ordering — not a quotation.

The unit
Why the answer is lengths, not metres
Everything is stocked as a 3 m length. A shorter piece is still cut from a whole one, and a few things take more than one length per set.
| What you order | Lengths used | Why |
|---|---|---|
| Skirting, cornice, batten or panel, full 3 m | Lengths used1 | WhyOne length is one whole stick |
| Cut into 3 × 1 m and sold as a pack | Lengths used1 | WhyAll three pieces come from the same stick |
| One sub-frame set (ซับวงกบ) | Lengths used3 | WhyA set is built from three lengths |
| A single piece cut shorter than 3 m | Lengths used1 | WhyThe cut piece ties up the whole length until the rest sells |
Limits
What this figure does not account for
- Mitres. Every corner eats a little extra; a room with several corners or a column wants 15% or more.
- Walls you cannot join across. A 3.2 m wall takes two lengths even though 2.8 m is left over — this total assumes offcuts get used on another wall.
- One model and one colour at a time. A room taking both skirting and cornice, or two finishes, has to be worked out once for each: an offcut of one does not cover the other.
- Delivery, which is free nationwide during the launch promotion.
- The price shown is today's price for the model and colour you picked.
- All of it is an estimate for budgeting and ordering. It is not a quotation.
