Face
Measure the visible flat area.
Measure after the yes
The finish earns the room before the metre count matters.
Measure the surface after the sample works in your light. That keeps the first decision emotional and the second decision practical.
Edges
Add extra for sides and trimming.
Round
Round up to avoid tight cuts.
Measure method
- Measure width and height in centimetres.
- Add 5 cm for each edge you want to wrap.
