Measure linear, area, polyline, angle, radius, and count elements on any PDF — with automatic scale calibration, live quantities, dynamic tables, and one-click CSV export. No install, no license keys, no waiting for IT. Runs on Mac, Windows, iPad, iPhone, Android, Chromebook, and Linux with full feature parity. Our construction takeoff software runs in any modern browser. Open a PDF drawing set, set the scale, and start measuring in seconds. Measurements flow into dynamic tables with custom formulas, waste factors, and totals — ready to export to CSV (Excel-compatible) or share live with your estimating team. ## Why measurement accuracy matters Takeoff accuracy is the foundation of every construction estimate. An accurate quantity multiplied by a stale unit cost still produces a bad bid, but an inaccurate quantity multiplied by anything produces a worse one. Industry studies consistently show that manual takeoff with a scale ruler and calculator has a 5–10% error rate, while digital takeoff with properly calibrated software brings that under 1%. On a $500,000 commercial project, a 5% takeoff error is $25,000 of exposure per bid — either overpricing and losing work, or underpricing and absorbing cost on jobs you win. Jobplans eliminates the math errors (the software does the arithmetic), the calibration errors (scale is set once per sheet and enforced), and the tracking errors (every measurement lives in a table you can export or audit). What is left is the estimator's judgment, which is the part that should never have been automated in the first place. ## Automatic scale calibration Scale calibration is the foundation of accurate takeoff. Jobplans reads text on every sheet — title blocks, general notes, and scale callouts — and auto-detects common scales like 1/4" = 1'-0", 1/8" = 1'-0", 1/2" = 1'-0", and 1:50 metric. When auto-detection is not reliable (scanned plans, rotated PDFs, drawings without a written scale), two-click manual calibration takes under 15 seconds: click two points on a known dimension, type the actual length, and every subsequent measurement on that sheet uses the calibrated scale. A common mistake with legacy tools is carrying scale from one sheet to the next when the sheets actually have different scales (a detail callout on a plan sheet, for example, might be drawn at 1/2" = 1'-0" while the main plan is at 1/8"). Jobplans handles per-sheet scale automatically so you never accidentally measure a detail at the wrong ratio. ## Linear measurement tool Precise linear measurements for lengths — perimeter runs, wall lengths, piping, cable tray, baseboards, flashing, curbing, crack sealing, striping, and any other linear scope. Click to start, click to end, and Jobplans reports the exact distance in feet, meters, or inches. Chain multiple segments on a single measurement to capture perimeters and bends. Assign measurements to categories so scattered linear elements roll up into combined totals in the measurement table without losing track of what each piece represents. ## Area and volume tools Calculate areas for flooring, walls, roofing, concrete slabs, painting, asphalt, landscaping, and every other surface scope. Jobplans supports polygon (click to place vertices), rectangle (drag to size), and circle (click center, drag to radius) tools. Perimeter is auto-calculated alongside area. Add a height value to any area and Jobplans produces the volume — useful for concrete, earthwork, aggregate base, and structural fills. Complex shapes with cutouts (a slab with a staircase opening, a wall with windows) are handled by subtracting interior polygons from the enclosing boundary. Running totals update live as you add or edit shapes, so you see the quantity change in real time instead of waiting for a recalculation. ## Polyline takeoff tool Polylines handle scopes that do not fit neat polygons or straight lines: irregular hardscape edges, piping runs with multiple turns, cable trays, ductwork centerlines, and fence lines. Jobplans supports both open polylines (for linear scopes with bends) and closed polylines (for irregular areas). Every segment contributes to a running total you see as you click, and each polyline is a single entity in the measurement table so you can label, categorize, and price it alongside your other quantities. ## Angle and radius tools Angles for roof pitches, wall corners, skewed walls, and any geometry where the measurement you care about is the angle rather than a length. Click three points and Jobplans reports the angle in degrees and optionally as a rise/run ratio (useful for roofing takeoffs). Radius handles curves and arcs — curved walls, radius corners on slabs, circular footings, curved landscape beds. Click the center, drag to the radius, and Jobplans reports the radius value, diameter, circumference, and arc length. Combined with the polyline tool for transitional curves, radius covers most of the curved geometry a contractor encounters on commercial drawings. ## Count tool For fixtures, equipment, receptacles, sprinkler heads, signage, light fixtures, door openings, and any scope where the quantity is "how many of these things on the plan." Click to drop a count marker, and every marker contributes to a running tally that flows into the measurement table. Count groups let you track multiple count scopes on the same sheet (switches vs. outlets vs. data drops, for example) and have them roll up separately. ## Dynamic measurement tables Measurements do not just produce numbers — they populate a live spreadsheet-style table with custom formulas, waste factors, and totals. Unlike passive "markup lists" in legacy PDF tools, Jobplans tables are actual estimating sheets. Link a material cost database by category and watch unit costs, labor hours, and totals update as you measure. Add waste factors (drywall 10–15%, flooring 10–12%, concrete 5–8%, lumber 12–15%) as explicit formulas rather than hidden adjustments in unit costs. Group by trade or assembly for clean subtotals and grand totals. Every column is customizable — add calculated fields for labor hours, add a markup percentage that rolls up to the total, carry forward historical productivity data from past projects. When measurements change, the whole table updates. When you add a new measurement, it appears in the right category with the right formulas already applied. ## CSV export that opens cleanly in Excel Every takeoff exports to CSV with every measurement row and its calculated fields — ready to open in Excel, Google Sheets, or any downstream pricing system. The file that lands in your estimating team's inbox rolls directly into their existing spreadsheet workflow or imports into bid assembly tools without reformatting. For contractors handing estimates off to accounting, project management, or clients, clean export behavior matters. Jobplans ships CSV export that matches how estimators actually use spreadsheets downstream — no manual cleanup, no column re-ordering, no lost context. ## Trade-specific examples **Concrete.** Area tool for slab area, with depth added for cubic yards. Linear tool for perimeter forming. Polyline for irregular slab shapes. Count for piers and footings. Angle tool for pitch on sloped drives. All measurements flow into a concrete takeoff template with rebar, formwork, waste, and pour rate formulas pre-wired. **Roofing.** Area tool for roof plan footprint, with pitch angle applied for true surface area. Linear tool for hips, valleys, ridges, and flashing runs. Polyline for irregular roof shapes and penetrations. Radius for curved eaves. Count for roof penetrations, drains, and scuppers. **Electrical.** Count tool for receptacles, switches, fixtures, panels, data drops, and every other device. Polyline for branch circuit homeruns. Linear for conduit runs and wiring pathways. Template library includes rough-in, trim-out, and fixture assemblies by room or area. **Drywall and framing.** Linear tool for wall lengths, doubled where needed. Area tool for wall surface (length × height). Count for openings to subtract. Waste factors set per-material in the template so quantities roll up to sheet count and stud count automatically. ## Who uses Jobplans measurement tools General contractors producing bids across multiple trades use Jobplans to consolidate takeoff into one tool instead of juggling spreadsheets per trade. Subcontractors across every CSI division use the trade-specific templates and measurement tools suited to their scope. Independent estimators working across multiple clients rely on flat pricing and cross-platform support. Design-build firms collaborate in real time across architecture, engineering, and construction roles. Field supervisors and superintendents pull up measurements on an iPad in the trailer or on the roof. ## Related guides and comparisons - [Construction takeoff software buyer's guide](/construction-takeoff-software) — the full category overview - [Construction estimating software guide](/construction-estimating-software) — extending takeoff into full bid assembly - [Digital takeoff software transition guide](/digital-takeoff-software) — switching from manual/paper to digital - [Blueprint measurement tool guide](/blueprint-measurement-tool) — physical vs digital measurement - [Jobplans vs Bluebeam Revu](/alternatives/bluebeam) — comparison with the legacy leader - [Jobplans vs PlanSwift](/alternatives/planswift) — comparison with the traditional Windows estimating tool - [Best takeoff software for contractors](/best-takeoff-software-for-contractors) — honest ranking of 7 tools ## Pricing Jobplans Basic is $29/month billed yearly ($348/year, 6+ months free) or $49/month billed monthly.

Every tool works with touch input on tablets and phones the same way it works with a mouse on desktop. **How accurate is Jobplans measurement?** Under 1% error rate with proper scale calibration. Manual takeoff with a scale ruler and calculator runs 5–10% error rates. The accuracy gain comes from the software doing arithmetic automatically, enforcing scale per sheet, and tracking every measurement explicitly. **Can Jobplans auto-detect scale from my drawings?** Yes for common architectural and engineering scales when the scale is written as text anywhere on the sheet — title block, general notes, or scale callout. When the text is unreliable (scanned or rotated plans), two-click manual calibration takes under 15 seconds. **Does Jobplans handle per-sheet scale correctly?** Yes. A common mistake with legacy tools is carrying scale from one sheet to the next when sheets have different scales (detail callouts at 1/2" on a 1/8" plan sheet, for example). Jobplans tracks scale per sheet automatically. **What happens when I update a measurement after I have taken it?** The measurement updates in place and every downstream quantity in the dynamic table recalculates. Waste factors, labor hours, unit costs, and totals all recalculate live. No manual spreadsheet refresh required. **How do waste factors work in Jobplans measurement tables?** Waste factors are explicit formulas on a column of the measurement table, not hidden adjustments in unit costs. Apply standard factors per material (drywall 10–15%, concrete 5–8%, lumber 12–15%) or override per project. Trade templates ship with industry-standard factors already in place. **Does Jobplans measurement software work on iPad and phones?** Yes. Full measurement toolset on iPad, iPhone, and Android with touch gestures for pan, zoom, and tool selection. Stylus support on iPad adds precision for small measurements. **Can I export measurements to Excel?** Yes. CSV export includes every measurement row with its calculated fields and opens cleanly in Excel, Google Sheets, or any downstream pricing system.
