📊 Plank size & coverage by floor type
Typical plank sizes and coverage per box — always confirm with the pack, since they vary by brand:
| Floor type |
Typical plank |
Per box |
| Laminate | 1.285 × 0.192 m | ~2.22 m² |
| Vinyl / SPC | 1.22 × 0.18 m | ~2.20 m² |
| Engineered parquet | 2.20 × 0.207 m | ~3.65 m² |
| Solid wood | 1.20 × 0.12 m | ~1.73 m² |
📐 Formula
Area (m²) = length × width, or enter it directly. Area with waste = area × (1 + waste%). Boxes = ⌈area with waste ÷ coverage per box⌉. Underlayment rolls = ⌈area ÷ roll coverage⌉. Skirting = ⌈perimeter ÷ length per piece⌉. Always round up.
🌍 Naming around the world
Flooring = piso / suelo = Bodenbelag · Laminate = laminado = Laminat · Vinyl/SPC = vinílico = Vinylboden / Klick-Vinyl · Underlayment = manta / espuma = Trittschalldämmung · Skirting / baseboard = guardapolvo / zócalo = Sockelleiste.
❓ Frequently Asked Questions
How many boxes of laminate flooring do I need?
Divide the room area (plus waste) by the coverage per box. For a 20 m² room with 8% waste = 21.6 m², and laminate boxes of 2.22 m², you need 10 boxes. Always round up and keep one spare box.
How much waste should I add for flooring?
About 5–8% for a straight layout, 10% for a brick/offset pattern, up to 15% for diagonal or rooms with many corners. Buy a little extra from the same batch for future repairs.
Do I need underlayment under laminate or vinyl?
Floating laminate and most click vinyl need an underlayment for sound, comfort and to level minor unevenness — unless the plank already has it pre-attached. It usually comes in rolls of ~10 m².
