The Sailrite Fabric Calculator

Slide-on Wire Hung Canopies

Unit of Measurement inches mm
Structure Width (fixed coverage) (?)
Intended width of the finished canopy. The canopy is fixed in its dimension across this distance -- it will not fold in this direction. Measure from what will be the fabric outside edge on the nearest panel to what will be the fabric outside edge on the farthest panel.
Structure Length (adjustable coverage)(?)
Intended length of the finished canopy. The canopy panels will fold to one side on this dimension. Measure from wire suspension hardware on one end of each panel to the opposite hardware set.
Fabric Width (?)
Useable width of fabric (often 46, 54, or 60 inches -- 1168, 1372, and 1524 mm)
Canopy Panel Length Too Great: The adjustable coverage length entered above may result in too much sag. This canopy would benefit from segmentation (create two or more shorter segments). We recommend adjustable coverage length of no more than forty feet or so (about 12200 mm) with fewer than 20 collapsing spans.
Canopy Panel Dimensions: There will be {{data.numOfCanopies}} canopy panels.
Each canopy panel will be {{data.widthOfCanopies}} {{data.UofM}} wide.
au t" Each panel will have {{data.numOfSpans |number:0}} spans.
Each span will be {{data.eachSpanFold}} {{data.UofM}} (from sleeve fold to sleeve fold).
Create pipe sleeves by sewing {{rnd(data.sleeveAllowance/2)}} {{data.UofM}} from folds.
Add {{rnd(data.endSleeveAllowance)}} {{data.UofM}} sleeve allowance at each end.
Panel length with sleeve allowances = {{rnd(data.panelLength)}} {{data.UofM}}.
Cut fabric length (includes an extra 6 inch safety factor) {{rnd(data.safeLength)}} {{data.UofM}}.
