Jitsuhiro: True Floor Area

Import a floor plan and calculate the true net usable area after subtracting pillars and structural walls. See what the listed “6.0 jo” room actually measures once columns eat into the space. ■ What you can do · Import floor plans from PDF, your photo library, or the camera (pick a page in multi-page PDFs; camera shots are auto-corrected for perspective) · Set the real-world scale by tapping two points on a dimension line · No readable dimension lines? Outline the unit and enter its total area to derive an estimated scale · Auto-detect pillar candidates, confirm or adjust them, then get the net area and the difference in jo · Place your own furniture at true scale to check walkway width and collisions before you move in. Layouts can be saved, overwritten, and deleted · Get a whole-property summary (totals in jo / m² / tsubo) and share result cards as images · Export all your data to a file and import it back — your data survives a device change · No floor plan yet? “Try with a sample” takes you straight to analysis and furniture layout (it doesn’t use your free quota) ■ Wall-center vs. inner-edge Japanese condo brochures usually measure to the centerline of walls and pillars (“kabe-shin”), while what you can actually use is closer to the inside of the walls (“uchi-nori”). Jitsuhiro’s net usable area subtracts pillars from the plan’s interior outline — a guide value that leans toward the inner-edge measure. ■ How it works · Every calculation runs on your device. Floor plans and measurements are never sent anywhere (no data collection, no account) · Everything works in Airplane Mode · One-time purchase, no subscription. Analyze 3 rooms free; buy once to remove the room limit ■ Please note · Results are estimates derived from the floor plan. Verify dimensions and areas with official documents and on-site measurement. · This app does not recommend or solicit the purchase of any particular property, and does not guarantee the accuracy of areas or dimensions. · Clearance thresholds are common residential-design guidelines, not safety or legal standards. · Designed for clean condo plans with dimension lines in mm.
