Measure the space
Use the canvas to capture room dimensions, labels, and odd shapes that matter for the project.
Carpet calculator
Complete Carpet Planning in One Connected Workflow
Calculate carpet directly from your floor plan with room geometry, roll width, layout design, seam lines, and reusable drops. Generate accurate cut sheets and exports without ever separating the drawing from the material calculations.
How it works
From measured room to carpet roll plan.
FloorPlanz Pro takes the actual room polygon from the canvas, fits carpet placements inside the room, tracks roll sections, and prepares an installer-friendly PDF cut sheet.
02
Plan the roll
Apply roll width, direction, seams, and waste assumptions to build a practical carpet plan.
03
Export the summary
Export room plans, the full unrolled roll layout, cut schedule, and reusable drops into one PDF.
Canvas to cut sheet
From Carpet Layout to Installer-Ready Cuts
See the same Great Room move through the real FloorPlanz canvas, roll layout, and exported cut sheet.
Follow a cut through the real workflow
Draw the carpet planThe real canvas keeps the room, direction, main piece, fills, and same-room drop together.
Unroll the materialThe roll view uses the same cut-group colours and labels as the canvas.
Export installer rowsThe PDF cut sheet repeats those labels so the drawing, roll plan, and schedule agree.

Fill planning
Selected layout
Try every practical direction
The planner tests each direction directly against the measured room polygon.
Main piece
The largest continuous carpet body covering the primary room span.
Fill piece
A narrower band needed when the room is wider than the roll or has a return.
Drop piece
Leftover material from the same room or a prior room that can be reused.
Seam
A boundary between installed pieces, shown as a dashed red line.
Cut sheet export
What the cut sheet gives your installer.
The export is not just a total. It is a visual production package that explains where each piece comes from, how it sits on the roll, and what can be reused.
Room plan diagrams
The PDF shows each room with colored carpet pieces so the plan is visually tied to the cut schedule.
Full unrolled layout
Roll sections are shown as continuous lanes with cumulative footage, section boundaries, and pile direction.
Cut schedule
Each row includes cut code, room, size as width x length, source, and cut section.
Reusable drops
Available drops are listed separately so useful leftovers remain visible and ready for reuse.
Implementation-backed details
Built from the same planning logic used in the app.
The production app builds an internal room shape, places carpet pieces, tracks seams, keeps reusable inventory, and exports a landscape PDF cut sheet.
Roll widths: 12 ft, 13 ft 2 in, and 15 ft.
Directions: horizontal, vertical, horizontal-flip, and vertical-flip.
Seams: rendered as dashed red lines on the canvas.
Cut colors: one color represents one physical roll cut group.
Sources: new roll, same-room drop, and prior-room drop.
Baseboard: adjusted room perimeters with door and opening widths deducted.
Summary: roll width, linear length, room area, waste ratio, cut sections, and reused cuts.
Material calculations
The Numbers Everyone Needs
A useful carpet calculator should do more than multiply length by width. It should explain net area, roll length, seams, and waste in a way the project team can verify.

FAQs
Carpet calculator questions.
What measurements does the carpet calculator need?
It starts with room length, width, and shape from the canvas, then applies roll width, seam direction, and waste assumptions.
Can it calculate carpet for multiple rooms?
Yes. The workflow is designed to keep room-by-room measurements together while also producing a project-level material summary.
Does it replace an installer review?
No. It is built to speed up estimating and proposal prep, but final ordering and install decisions should still be reviewed by a qualified flooring professional.
What roll widths does the calculator support?
The implementation stores roll widths as 144, 158, and 180 inches, covering 12 ft, 13 ft 2 in, and 15 ft carpet goods.
What is included in the cut sheet export?
The cut sheet PDF includes a summary, room plan diagrams, a full unrolled carpet layout, a cut schedule, and available reusable drops.
How are reusable drops handled?
The calculator tracks same-room and prior-room drops, then can reuse suitable offcuts for fill pieces, halls, closets, and smaller sections.
Try the complete FloorPlanz workflow.
The calculator is strongest when it stays connected to the plan, room labels, and PDF export.
