Understanding the result
This estimate is a planning worksheet for standard rectangular upholstery panels. It groups similarly sized pieces into rows across the usable fabric width, includes a modest edge allowance, and rounds panel-row lengths to the selected pattern repeat before adding waste. It does not replace an upholsterer’s cutting plan, especially for curved seats, skirts, piping, directional patterns, nap or matching across a settee.
- These results support research and planning; they do not independently establish authenticity, age or value.
- Keep direct observations separate from assumptions, seller claims and conclusions.
- Seek qualified, object-specific advice when the decision affects value, repair, safety or a legal transaction.
Good records improve research
Keep original observations separate from conclusions. Photograph the whole object and relevant details in even light; record dimensions, labels, maker marks, repairs, provenance and the references consulted. Do not alter the object just to obtain another clue.
Methodology and limitations
For each panel group, the tool estimates how many pieces fit across the usable fabric width, rounds the number of cut rows upward, and sums the row lengths. A 5 cm allowance is added to each panel edge. Pattern rows are rounded up to a repeat multiple, then the user-entered waste percentage is applied. The model assumes matching dimensions and orientation within each group and is not a full cutting-layout optimiser.
Three panels each measuring 60 × 60 cm have 1.08 m² total area. On 140 cm usable-width fabric, raw area is about 0.77 linear metres before pattern matching, orientation and cutting waste; actual required length may be substantially greater.
Historical objects are often repaired, refinished, reassembled or made from more than one material. Modern reproductions may imitate older processes. A likely match should always be phrased as a research hypothesis unless it is supported by a qualified, object-specific assessment and trustworthy documentation.
Frequently asked questions
Can I order fabric based on the result alone?
Treat it as a preliminary estimate. An upholsterer should verify panel orientation, cutting layout, pattern matching, piping, skirts, boxing, tufting and any inside/outside backs before you order expensive fabric.
Does fabric width matter?
Yes. Narrower usable width usually increases linear length. Use the actual usable width rather than the full bolt width if selvages or damaged edges cannot be used.
How does pattern repeat change yardage?
A repeat can require each panel to start at a matching point in the pattern, causing offcuts. This tool adds a repeat allowance; complex repeats may require more.
Should I count both sides of a cushion?
Yes, where both faces are covered. Add separate panels or ask the upholsterer to include boxing, underside fabric and zipper allowances.
Why is a settee harder to estimate than a chair?
Long panels, pattern matching, skirts, curved forms and repeated cushions reduce cutting efficiency. Make a dimensioned panel list and get a professional cutting plan.
