No more manual math or complex formulas—just fast, accurate results across various units. Key Features: • Comprehensive Unit Support: Seamlessly switch between Metric (mm, cm, m, km) and Imperial (in, ft, yd, mi) systems. • Custom Scale Ratios: Set any ratio (e.g., 1:100, 2:500) to match your specific drawing or model requirements. • Instant Conversion: Input your actual dimensions and see your model scale immediately in your preferred unit. • Clean & Intuitive UI: Designed for professional use with a focus on speed and clarity. Who is it for? • Architects & Engineers: For quick blueprint checks and site plan scaling. • Model Builders: Perfect for RC planes, trains, and architectural miniatures. • Interior Designers: Scale furniture and floor plans with ease. • Students: A reliable companion for technical drawing and geometry assignments. Download Scale Calculator today and take the guesswork out of your next project!

A scale converter for people who build models. Pick a scale — HO, N, O, 1:35 armour, 28mm heroic, 1/4" = 1' — type a dimension, and read the answer as you type. Free, offline, no account, no ads. THREE ANSWERS, ONE SCREEN • Real → model — how big is a 40-foot boxcar in HO? • Model → real — this part measures 92 mm; what is that full size? • What scale is this? — give a real length and the model length it has to come out at, and get the ratio. COMPARE ACROSS SCALES A second view takes one measurement and shows it in every scale in a hobby group at once — model railway gauges, military armour, aircraft, tabletop miniatures — with a proportional bar per row so you can judge the sizes by eye instead of reading numbers. UNITS HOBBYISTS ACTUALLY TYPE It parses what you would write on a workbench note: 250mm, 2.5 cm, 5' 6", 5ft 6in, 1 1/2", 3/4", 1-1/2". Feet-and-inches and fractional inches are first-class output formats, not an afterthought — fractions come back as fractions, rounded to the precision you choose. SCALES INCLUDED • Model railways — Z, N, TT, HO, OO, S, O, G and more • Military and armour — 1:16, 1:35, 1:48, 1:72 • Aircraft — 1:32, 1:48, 1:72, 1:144 • Cars — 1:18, 1:24, 1:43, 1:64 • Tabletop and wargaming — 15mm, 28mm heroic, 32mm, 54mm • Architecture — imperial drawing scales like 1/4" = 1' and metric 1:50, 1:100 • Any custom ratio you type WORKS COMPLETELY OFFLINE No account, no sign-in, no sync, no paywall and no advertising. Every calculation happens on your device, and nothing you type is ever sent anywhere. The only thing the app ever sends is anonymous usage data — which scales and modes get used — and you can switch that off in Settings. For model railroaders, scale modellers, miniature painters, RC builders, dollhouse makers, architects and anyone who has ever stood in a hobby shop doing long division on their phone.
