Count the Binding Length Left After Measured Joining Loss — Free
Adding strip lengths misses the material used at every join. Enter equal-strip runs and a joining loss you measured to count remaining binding length while keeping separate runs and final closure allowances distinct.
The proof surface
Pleat calculators account for fabric folded into a garment. This packet accounts for length consumed when strips become a continuous binding run: number of joins is strips minus one, and independent runs do not become one joined length.
Inputbinding run | length of each equal strip cm | strips in that run; measured length lost per completed join in cm

Sample, not your facts: Illustrative inputs: Red binding run | 110 | 4; Blue binding run | 80 | 3. Measured length lost per completed join in cm = 5. Usable stock across separate binding runs: 655 usable centimetres. All records are invented.
Before using the binding-join cut packet
Make a sample join using the same strip width, seam method and trimming practice as the job, then measure the reduction in end-to-end length. The app deliberately uses that measurement instead of claiming a diagonal joining formula applies to every method. Rows assume equal strip lengths within each run; if the strips differ, total them carefully outside the form or separate the plan. A finished binding may also need a closing join, end trimming, turns, handling slack and shrinkage allowance. Those are not silently included. The packet makes the internal joining deduction visible so a sewer can ask whether the remaining length covers a separately measured edge. It does not judge seam quality, choose cutting direction or tell you whether a particular material is safe to machine.
Why the flat version breaks
Using one join for every strip
The first strip starts the run and needs no internal join. Counting N joins instead of N minus one overstates the deduction.
Adding separate runs as one continuous length
The headline totals stock across rows. Joining those rows together would consume another measured join and may not be appropriate for the project.
Treating internal joins as the whole allowance
Closing the binding, trimming ends and handling turns can use more length. These separate construction choices must remain outside the stated internal-join calculation.
How to work the binding-join cut packet
Measure loss with your own joining method
Use centimeters lost per completed internal join, measured on a sample with the same width and trimming practice. A zero loss is allowed only when that convention genuinely deducts nothing; no standard allowance is supplied.
Count strips within one continuous run
Use a positive whole strip count and equal length per strip for each row. Red and blue sample runs remain independent. The total is aggregate usable stock, not proof that all rows can serve as one continuous binding.
Deduct strips minus one joins
A run of N strips has N minus one internal joins. Usable length equals N times strip length minus N minus one times loss. A single strip has no internal joining deduction; additional closure or end-trim loss is outside this equation.
Check the finished edge separately
Compare each run with the actual edge length and the additional allowances your method needs. Ask an experienced sewer or pattern provider about unfamiliar construction; inspect a real sample before cutting a critical project.

What this is built on
Method: A run of N strips has N minus one internal joins. Usable length equals N times strip length minus N minus one times loss. A single strip has no internal joining deduction; additional closure or end-trim loss is outside this equation.
All sample records, dates, quantities and labels are invented. No outside policy, contract, rate, clock offset, measurement or accessibility standard is represented as verified.

Before: summed strips obscured the length used at their joins. After: strips-minus-one joining loss is visible without silently including final closure.
Three worked readings, with different inputs
Sample A — typical inputs
Red binding run | 110 | 4
Blue binding run | 80 | 3
Setting: Measured length lost per completed join in cm = 5. Expected summary: 655 usable centimetres.
Four 110-centimeter strips contain 440 centimeters before joining. A continuous run of four strips has three joins, so fifteen centimeters of measured loss leaves 425. Three eighty-centimeter strips have two joins and leave 230. The headline totals 655 centimeters across the two separate runs; it does not join red and blue together without another loss. The five-centimeter setting is an invented measured allowance, not a universal diagonal-seam formula.
Sample B — changed plan
Red binding run | 110 | 5
Blue binding run | 80 | 4
Setting: Measured length lost per completed join in cm = 5. Expected summary: 835 usable centimetres.
Adding one strip to each run also adds one join to each. Red becomes 550 minus twenty, or 530 centimeters; blue becomes 320 minus fifteen, or 305. Combined usable stock across the separate runs is 835. Comparing the alternate with the first sample shows that an extra strip contributes its full length minus one added join loss, not its full length alone. End trimming and the final closing seam remain separate allowances.
Sample C — boundary convention
Single long strip | 110 | 1
Short boundary pair | 5 | 2
Setting: Measured length lost per completed join in cm = 5. Expected summary: 115 usable centimetres.
One strip has no internal joins, so the 110-centimeter strip keeps its modeled length. Two five-centimeter strips at five centimeters lost for their one join leave five centimeters in the arithmetic, totaling 115 with the long strip. The boundary does not certify that such short pieces can be sewn successfully; width and seam geometry are not modeled. A joining loss greater than the strip length is rejected for a multi-strip run instead of producing a misleading material plan.

No API key or AI call is built into this tool. Free-tier content may be used to improve products.

Format only these fictional or non-sensitive notes for a binding-join cut packet. Return strict JSON shaped as {"rows": [{"label": "string", "cells": ["string", "string"]}], "setting": "string"}. The columns are binding run | length of each equal strip cm | strips in that run; the setting is Measured length lost per completed join in cm. Keep all supplied strings and quantities exactly; do not calculate, infer missing entries, invent dates or add advice. If any required value is missing, return an empty rows array and ask me for it separately. I will verify every cell against my source and manually transcribe rows using vertical bars before running the local calculator.
An AI response is not executed, fetched or trusted as a result. Missing values remain questions; the strict local parser checks the rows you actually enter.
