📐 Как мы считаем
The door trim calculator uses the following formula:
Perimeter per Door = 2 × Height + Width
Total Length = Perimeter × Number of Doors
Trim Strips = ⌈Total Length / 2.5m per strip⌉
Standard Trim: Door trim pieces typically come in 2.5m lengths.
Coverage: Each door requires trim on both sides and top (3 sides total).
