Scala Architectural Scale
This app allows users to measure printed architectural and engineering drawings directly on their device. It supports both known and unknown scales, offering fixed and variable scale options for precise measurements. Users can also select secondary units for quick conversions.
- Fixed and variable scale measurement
- Supports unknown drawing scales
- Secondary unit conversions (metric, decimal feet, feet/inches)
- Adjustable measurement precision
- Extensive scale options for architectural, engineering, and metric drawings

Let Scala Architectural and Engineering Scale change the way you measure printed drawings on the go and at your desk. With fixed and variable scales there is no limit to measuring a printed drawing of any scale, even if the scale is unknown. FIXED SCALES If you know the scale of a drawing, place your device on the drawing, scroll to the scale of the printed drawing and watch the chosen scale slide in. VARIABLE SCALES If the scale of a drawing is unknown, slide your finger on the variable scale and match the scale of one known element, lock it and use it to measure all elements on that drawing. MEASURING Slide the measurement slider in fixed or variable scale modes, along the scale to see the desired measurement displayed. SECONDARY UNITS Choose secondary units to be displayed while measuring, to quickly convert between metric, decimal feet and feet and inches. PRECISION Control the precision of the measurement units. —-— Scala Free Version includes: ARCHITECTURAL Fixed Scales: Full Scale (12”=1’-0”), 6”=1’-0”, 3”=1’-0”, 1 1/2”=1’-0”, 1”=1’-0”, 3/4”=1’-0” Variable Scale Range: Between full scale and 1/32”=1’-0” ENGINEERING Fixed Scales: 1”=10’, 1”=20’, 1”=30’, 1”=40’, 1”=50’ and 1”=60’ Variable Scale Range: Between 1”=10’ and 1”=300’ METRIC Fixed Scales: 1:1, 1:2, 1:5, 1:10, 1:20, 1:25 Variable Scale Range: Between 1:1 and 1:1000 Scala Full Version includes all scales above plus the following: ARCHITECTURAL Fixed Scales: 1/2”=1’-0”, 3/8”=1’-0”, 1/4”=1’-0”, 3/16”=1’-0”, 1/8”=1’-0”, 3/32”=1’-0”, 1/16”=1’-0”, 1/32"=1'-0" ENGINEERING Fixed Scales: 1"=80', 1"=100', 1"=200', 1"=300' METRIC Fixed Scales: 1:30, 1:40, 1:50, 1:75, 1:100, 1:125, 1:200, 1:250, 1:300, 1:400, 1:500, 1:1000 —-—
ArchitectScaler
Read full descriptionHide full description
ArchitectScaler turns your iPhone and iPad into a scale ruler, a drafting calculator, and the small toolbox of conversions architects, designers, and students actually reach for. No triangular ruler, no clunky calculator, no "calculate" button - you type, and the answer is already there. Version 2.0 opens on a Home screen of tools. Tap one and you are working. THE CONVERTER Set a scale once, then keep a live ledger of dimensions. Type a real-world length to get the drawing length, or type a drawing measurement to get the real thing - both directions, instantly. Name any row ("North wall", "Door", "Site") so a list of numbers reads as a list of things. Your rows, scale, and units are saved between launches. FEET AND INCHES, PROPERLY Type 12'-6 1/2" the way you would write it. Scales like 1/4" = 1'-0" are first-class, and a keyboard row puts the ' " - and / marks one tap away. Change a unit and the app converts the value rather than re-reading the same digits. THE TOOLS Find scale from a drawing - measure any labeled dimension on a print and get the ratio back, with the nearest named scale offered as a one-tap match. Slope and pitch - convert between 1:20, percent, degrees, and roof pitch, and get the fall over a run. Area and volume - scale squared and cubed, from square millimeters through hectares and square inches through acres, plus cubic meters, feet, and yards. Rescale and print - the copier percentage that takes a drawing from one scale to another, and what a line measures after the change. Sheet fit - whether a plan fits a sheet inside its margins, and the largest named scale that would. ISO A0 to A4, ANSI A to E, and Arch A to E1. Feet and inches - add and subtract lengths in drafting notation without converting to decimal first. Scale bar - generate a printable graphic scale and share it straight into a drawing. Model making - turn a real wall thickness into the nearest card, foam board, or acrylic sheet, and see how far off that substitution puts you. BUILT FOR THE WAY YOU WORK Metric and imperial: mm, cm, m, km, in, ft. Metric, architect, and engineering scale presets, or type any ratio you like - 1:48 and 1:37.5 are both fine. iPhone and iPad. Light and dark, following your system appearance. No account, no ads, no tracking, no data collection. Every calculation stays on your device. Built by an architect, for architects, interior designers, engineers, students, model makers, and anyone who works from a scaled drawing.

Verdict
The clearest difference is in-app purchases: ArchitectScaler at none against Scala Architectural Scale's 1. Scala Architectural Scale's advantage is update cadence (every 4 months vs every 14 months) and iOS requirement (15.6 vs 17.6). On price, ads and device support there is nothing between them.
