Compare whole-width carpet strips with four-wall trim, roll-edge loss and extra cut length. Inspect seam candidates and both run directions for one rectangular room.
Choose your path
Review whole-width carpet strips with transverse/end trim, usable roll width and two run-direction candidates without installation approval.
Understand why roll width equal to room width may not cover transverse trim.
Enter actual roll width and four-wall trim, inspect strips and seam candidates.
Sees the geometric effect of both transverse and run allowances.
Compare quantities without inventing a seam or pile approval.
Enter usable edge losses and extra cut length; compare both run candidates and strip records.
Coordinates real product, pattern, pile and seam constraints separately.
Retain a complete cut geometry record.
Review original units and every strip, download and explicitly save to the Project.
Can reconcile the candidate with a separately reviewed purchasing schedule.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
This tool is part of these guided projects. Each project provides step-by-step instructions with checklists and all the tools you need in one place.
Tools you might need next
Review laminate edge rows, starter lengths and joint spacing, then reconcile whole cartons, matching inventory and separately approved underlay.
Build a measured multi-area takeoff, compare exact carton coverage with a reviewed source-tile count, and price whole packages after matching inventory.
Review fixed-plank vinyl rows and actual cartons, with separate product-approved click/floating or glue-down accessory quantities.
Subtract both entered roll-edge losses from purchased roll width. Divide room cross-width plus both wall trims by usable width and round up to whole source cuts.
Each cut includes the room run, trim at both end walls and separately reviewed extra length. Full purchased roll width determines cut area.
Show two independent candidates and installed strip coordinates inside the room. Trim and discarded edges are omitted from the drawing; no automatic pattern matching or offcut reuse is credited.

See why transverse wall trim can require another source strip.
Inspect seam coordinates, edge losses and extra cut length before reviewing the actual seam/pile plan.
Download every strip and both bounded candidates for comparison with a reviewed purchasing schedule.
Use actual measured scope and a product-specific reviewed seam, pile and cutting plan.
Confirm site conditions, product instructions, supplier terms and installer acceptance separately.
Compare whole-width carpet strips with four-wall trim, roll-edge loss and extra cut length. Inspect seam candidates and both run directions for one rectangular room. Original values, units and source revisions remain traceable; arithmetic is not installation approval.
