Measure areas, counts, and volumes directly from PDF blueprints, sketches, and site plans.
Simple enough for DIY projects, accurate enough for contractors. Trace your plan, calculate square footage, and generate a material estimate instantly. No signup or software installation required.
Free construction takeoff software for contractors, builders, remodelers, and homeowners. Measure square footage, linear footage, and cubic yards directly from blueprint plans, site drawings, and hand sketches.
Upload a blueprint, PDF, hand-drawn sketch, or photo of your space, set the scale, trace the area, and instantly calculate measurements with optional waste factors. Use the tool for decks, patios, concrete slabs, tile layouts, fencing, drywall, paint, gravel, pavers, and other construction projects.
Four simple steps to measure blueprint area, calculate square footage, and estimate materials in minutes.
Upload a PNG, JPG, or PDF of your deck plan, construction drawing, site plan, hand-drawn sketch, or photo of your space.
Enter the blueprint scale (e.g. 1/8″ = 1’) or calibrate using a known measurement. Fractions supported.
Click or tap to trace the deck outline as a polygon or drag a rectangle over the plan.
Instant square footage with optional waste factor. Get a ready-to-use shopping list. Copy or print the estimate report.
Material calculators and project estimators — from patio paver calculator to roof takeoff tool.
Find how much material you need: trace your plan (blueprint, sketch, or photo), get a ready-to-use shopping list.
Calculate deck square footage directly from blueprint construction plans. Supports multi-section decks, polygon tracing, and waste factor.
Calculate slab area and estimate cubic yards of concrete directly from blueprint plan drawings.
Trace floor or wall areas directly from construction blueprint plans and estimate tile count with waste overage.
Calculate fence perimeter, post count, and panel count directly from a site plan or property survey blueprint.
Patio paver calculator: measure patio square footage directly from construction blueprint drawings for pavers or poured concrete estimates.
DIY deck material estimator: estimate boards, fasteners, and framing directly from blueprint plans. Includes board count, linear footage, and fastener estimates.
Calculate roof area, roofing squares, shingles, and underlayment from blueprint plans. Enter pitch for accurate sloped surface area with waste factor.
Calculate drywall sheet count for walls or ceilings directly from blueprint construction plans. Supports 4×8, 4×10, and 4×12 sheets with waste factor.
Paint calculator for one room: estimate paint gallons needed for walls or ceilings directly from blueprint plans. Supports multiple coats and coverage rates.
How much mulch do I need for my garden? Estimate landscaping material volume in cubic yards from site plans. Works for gravel, mulch, and aggregate with depth and truck load estimates.
Estimate paver quantities for patios, walkways, and driveways directly from blueprint plans. Accounts for paver dimensions, joint spacing, and waste.
Blueprint Calc helps contractors, estimators, and DIY builders measure plans faster and reduce material overbuy.
Unlike spreadsheet-based estimates or manual scale calculations, Blueprint Calc lets you trace plans visually and get instant quantities for area, materials, and waste. It works directly in the browser with no install required.
Built for professionals and homeowners who need fast, accurate measurements from construction drawings. No construction jargon required — material calculators and project estimators for everyone.
Use on iPhone, Android, tablet, or desktop. Optimized for on-site use with one hand.
Blueprint images are processed entirely in your browser. Nothing is uploaded to any server.
No account, no download, no learning curve. Measure in minutes, not hours.
Upload PDF plans directly — the first page is automatically rendered for tracing.
Upload your blueprint image or PDF, then set the scale by clicking two points on a known dimension (such as a dimension line on the drawing). Once calibrated, trace the area you want to measure by clicking around its perimeter. The calculator converts your traced pixels to real-world square footage automatically.
Most residential construction plans use a scale of 1/4″ = 1’ or 1/8″ = 1’. The scale is usually printed in the title block of the drawing. You can enter the scale directly (fractions supported) or use the calibration tool to click two points of a known measurement on the plan itself.
Yes. The Patio Area Calculator and Concrete Slab Calculator both support blueprint tracing. Upload your construction drawing, trace the slab or patio boundary, and get square footage plus material estimates (cubic yards, bag count, or paver count).
Yes. All calculators are fully touch-optimized for iOS and Android. Use two fingers to zoom and pan the blueprint, and tap to trace the area. PDF blueprints are supported on mobile as well.
You can upload PNG, JPG, GIF, WebP, and PDF files. PDF blueprints are rendered to an image (page 1) automatically, so you can trace them just like any other plan.
No. All image processing happens locally in your browser. Your blueprint never leaves your device and is not uploaded to any server. When you close the tab, the image is gone.
Yes. The calculator is fully mobile-responsive and supports touch drawing on iOS and Android. You can also install it as a Progressive Web App (PWA) for offline use directly from the browser.
