Work out how many flooring planks or boxes to buy for laminate, vinyl, or hardwood flooring, with a wastage allowance for cuts.
Add 10% for a standard room, and 15% or more for rooms with lots of corners, closets or diagonal laying patterns.
Check the box — it's usually printed as plank dimensions (e.g. 7 in × 48 in) or as total sq ft coverage per box directly.
Yes, where possible — colour and finish can vary slightly between production batches, especially with laminate and engineered wood.
