Floor: Calculator & Scheme

How many packs of flooring to buy for a room, and how to lay the planks so that less of the material ends up as waste. The calculator answers both: it gives the number of packs, builds the laying scheme row by row, and produces a cut list you can actually cut by. The count follows the rules of laying rather than dividing room area by plank area. The expansion gap, the joint offset between rows and the minimum plank length are all taken into account — the same constraints manufacturers put in their instructions. WHAT IT WORKS OUT • How many planks and packs a room needs • Several layout options, sorted by how many planks they consume • The share of waste in the material you buy • Offcuts with an intact lock are reused at the start or end of later rows WORKS WITH ANY PLANK FLOOR The count works from the plank's own size rather than the name of the material, so it fits anything laid in rows with staggered joints: laminate, vinyl plank (LVT) and SPC, click vinyl, engineered or solid wood flooring, parquet blocks. Planks from 200 × 50 mm, packs from 1 to 1000 pieces. ROOMS THAT ARE NOT SQUARE • Each of the four walls is measured on its own, plus one diagonal — nothing is assumed about the corners being square • A sketch on the form redraws the room as the numbers are typed and names every wall • The rows come out at the lengths they will really be cut to, and their ends carry the slant the walls give them • Measurements that cannot close into a room are refused before they reach the calculation ROOMS WITH CUT CORNERS • Six shapes to pick from, each shown as a picture rather than described in words: rectangular, walls of unequal length, a cut corner, two cut corners, L-shaped and T-shaped • A corner run straight across at 45°, or taken out square: the overall size and two or three measurements of the cut itself • Which corner the cut is in — or which wall a pair of cuts stands on — is tapped on the sketch • The row that crosses an inside corner is laid long and notched round it, so no strip of floor is left bare • Laid along the room or across it LAYING PARAMETERS • Direction: along the length, along the width of the room, or diagonally at 45° • Expansion gap from the walls • Joint offset: 1/2, 1/3, 1/4 of the plank length, or an exact value • Minimum plank length: nothing shorter gets laid • The pattern start is chosen so that in every row both the first and the last plank stay at or above that minimum SCHEME AND CUT LIST • A laying scheme with numbered planks and their sizes • A cut list: every row plank by plank, reusable leftovers and waste • The scheme and the cut list save to one PDF, and the cut list also sends as text MILLIMETRES OR FEET Metric, or imperial in feet and inches with fractions down to 1/16". You can switch systems at any point — the sizes already typed are converted for you. TWELVE LANGUAGES English, Russian, German, Spanish, French, Italian, Polish, Portuguese, Turkish, Czech, Swedish and Bulgarian. The language is picked on first launch and can be changed later in settings. NO INTERNET, NO ADS The app requests no permissions and never goes online: the whole calculation runs on your device. No ads, no account, no data collection. WHO IT IS FOR Anyone laying a floor themselves who wants the exact number of packs before the trip to the shop. And anyone laying floors for a living: the scheme and the cut list can be sent straight to a client or a workmate.
