Do I need to install anything, and will it run on the tablet I take to site?

No install and no account - it opens in a browser on desktop, tablet or phone, and the left panel collapses on small screens. The 3D and Split tabs need WebGL and hide themselves on devices that lack it, so a modest tablet still gets the 2D plan, the material engine and the report. Projects live in that browser's local storage, so use the JSON export to carry a job from the office machine to the site tablet.

What does it cost, and can I use it on paid client work?

It is free: no licence key, no seat count, no sign-up. Everything runs in your browser - room dimensions, your prices and the reports stay on your own machine in local storage; the only network feature is an optional "who is online" badge. Use it on paid jobs as you like; the printed report already carries the note that the figures are approximate.

How exact are the numbers, and what can it not do yet?

It is a takeoff and budgeting tool, not a certified estimate: quantities follow the consumption, waste, coats, pack size and prices you type, so check site measurements, product data sheets and current prices before you bid. Not there yet: skirting length, applying one material to several surfaces at once, editing a drawn room's dimensions after the fact, and detection of self-intersecting drawn plans. The interface is Turkish only for now.

MetrajNo More Losing Money on a Wrong Quote: Get Quantities, Materials and a PDF Quote the Moment You Enter the Sizes

Instead of juggling a tape, a notepad and Excel, you give the client the figure on the spot. Type room sizes; openings and columns come off automatically. Net areas become 11 materials, packs, material and labour cost, and a printable report.

Left: the job by hand. Right: the same job with the plugin.

Metraj

Every feature, at a glance

What the plugin does for you, drawn rather than listed.

Type it once, the room is measured

Enter width, length and height once; floor, ceiling and all four walls come back measured, in the 2D plan and the 3D view alike.

Net area, a sound quote

Doors, windows, columns and beams come off the gross area on their own, so every material works from the same net figure, not a rough guess.

11 materials from one net area

Paint inside and out, satin plaster, epoxy, wallpaper, ceramic, granite, marble, laminate, PVC and carpet, each with its quantity, packs and cost.

Real tile and box counts

Ceramic, granite and marble work from the real size, like 60×60 or 60×120, and the pieces per box, so piece and box counts are true.

L-shaped rooms and lift shafts too

Draw right-angled plans on squared paper by direction and length; area and perimeter show live, and materials and report work as usual.

Change a number, the report follows

Edit a size or a price and the totals in TRY, USD or EUR follow at once; the report leaves as a PDF with the plan, Excel-ready CSV, JSON or PNG.

01
Type It Once, the Rest Comes Measured
Width, length, height — once. Floor, ceiling and four walls come back measured, in 2D and 3D, ready to price.
02
Net Area, a Sound Quote
Doors, windows, columns and beams come off the gross area on their own. Every material works from the same net figure, so the quote never rests on a rough guess.
03
Change One Number, the Totals Follow
Ready even at the negotiating table: move a wall or edit a price, and quantity, packs, labour and project totals follow — then leave as PDF, CSV, JSON or PNG.

The technical bit

For the people who read the manual first.

Works with: Desktop browser - no install, no account · Tablet · Phone (mobile layout with collapsible panel) · WebGL required for the 3D and Split tabs (tabs auto-hidden without it) · Data stored locally in the browser (LocalStorage); JSON export to move projects between devices
Interface languages: tr

Rooms are entered as width x length x floor-to-ceiling height; geometry is kept in millimetres internally and shown in m, cm or mm.
Six surfaces per room (floor, ceiling, wall 1-4) are created automatically, and surface ids survive a resize so material settings stay attached to the right wall.
Door and window openings are placed from the left or right edge and from floor or ceiling - the missing value is computed - and checked for out-of-wall placement, ceiling overrun, overlap and negative size.
Columns and beams are entered as count x size per surface or drawn as rectangle, circle or line with a real plan position and elevation range; both are deducted from the gross area.
A gross / opening / net area card feeds every calculation, driving 11 material engines written as pure, tested functions: interior and exterior paint, satin plaster, epoxy, wallpaper, ceramic, granite, marble, laminate, PVC flooring and carpet.
Ceramic, granite and marble can be calculated from the real product size (60x60, 60x120 and so on) with pieces per pack, returning true piece and pack counts; the classic m2-per-pack entry stays available.
The SVG 2D plan has click-editable dimension labels synced both ways with the left panel; the React Three Fiber 3D view adds orbit, isometric/top/front presets, transparent ceiling and wall hiding, and the 3D and Split tabs hide themselves on devices without WebGL.
A drawing tab handles orthogonal free-hand plans - L-shaped rooms, lift shafts - with direction plus length entry on squared paper, live area and perimeter, and closing-edge validation; drawn rooms run the same opening, material, 3D and report pipeline.
Output: printable PDF report with the plan drawing and surface, opening and material tables, Turkish-Excel-compatible CSV, JSON project import/export and a PNG of the plan; totals in TRY, USD or EUR.
Projects are stored in the browser under a versioned LocalStorage key, with 50-step undo (Ctrl+Z), Escape to clear selection, an error boundary offering Reset and Reload, and a build-id stamp in the left panel; 119 automated tests across 14 files, all green.
