FLATPLANNER
Plan your space before you move a thing — floor-plan basics, room layouts, and the measurements that matter.
From measuring a room and estimating flooring and paint to planning furniture walkways, sizing a rug, and reading a scaled plan, FlatPlanner pairs free hands-on layout calculators with practical guides and a richly illustrated museum. Plan the space before you move a thing.
Floor Plan & Room Layout Calculators
Free tools for every room — room area & square footage, flooring and paint quantity, furniture clearance, rug size, and a floor-plan scale converter.
Room Area & Square Footage Calculator
Get a room's floor area in square metres and square feet from its length and width — including L-shaped rooms — plus the perimeter for skirting and paint.
Flooring Material Calculator
Turn a floor area into how much flooring to buy, with a waste allowance for cuts and pattern matching and whole-box rounding.
Paint Quantity Calculator
Estimate the litres a room's walls need from its size, the coats, and the paint's coverage — with doors and windows removed.
Furniture Clearance & Walkway Planner
Check whether a sofa, bed, or table leaves a comfortable walkway — the clearance on each side against a sensible minimum.
Rug Size Calculator
Find the right rug for a room from the bare-floor border you want to keep — the ideal dimensions plus the nearest standard size.
Floor Plan Scale Converter
Convert between a measurement on a scaled plan and the real distance — metric ratios like 1:50 and imperial scales like 1/4 inch = 1 foot.
Home & Interiors Museum
Wander an illustrated museum of the ideas behind the rooms we live in — the language of architectural drawing and floor plans, the story of interior design, the furniture that fills a home, and the famous houses whose layouts changed how we build, each in its own gallery. Every entry, image, and fact is drawn from Wikipedia and Wikimedia Commons.
