Interior film cutting & quantity calculator
CutBloom helps interior-film installers and DIY renovators work out how much film to buy and how to cut it with the least waste. Enter the width and height of every surface you plan to wrap — cabinet doors, panels, frames, walls — along with the quantity and whether the pattern direction is fixed. CutBloom then lays the pieces onto a roll of your chosen width and reports the film length in metres, the waste (loss) ratio and a visual cutting layout. Everything runs in your browser: nothing you type is uploaded.
Why efficient nesting matters
Interior film is sold on rolls of a fixed width (commonly 1220 mm). Because you pay for the full length of roll you use, off-cuts left beside a piece are money lost. Good nesting — arranging pieces so they share roll length — directly lowers material cost. Quotes usually add a loss allowance of 10–20 %; estimating it up front keeps your bids accurate.
Grain and pattern direction
Wood-grain, marble and hairline films have a direction, so those pieces cannot simply be rotated to fill a gap. Mark them as grain-locked and CutBloom keeps their orientation; mark plain colours as rotatable so they can be turned 90° to pack tighter. This is what makes film nesting harder than cutting plain board.
Two layouts: Compact nesting vs Straight rows
The tightest layout is not always the easiest to cut, so CutBloom computes two arrangement strategies every time and shows them side by side at the top of the result. Compare the film length each one needs and pick the one that suits your cut — your choice drives the layout, cutting list and quote.
Save material (default) uses a maximal-rectangles algorithm that tracks the real gaps between pieces, so small offcuts drop into holes instead of starting a new row. It also tries several arrangements and keeps the shortest. The result uses the least film — typically 5–15% less waste. For ordinary rectangular panels the tightest layout it finds can usually still be cut with straight passes; only occasionally does squeezing out the last bit need an interior or L-shaped cut. Best when film cost matters most, or for a purchase estimate.
Easy cutting arranges the pieces into full-width rows (shelves) of similar height. Because every row spans the whole roll width, you cut it out with the fewest, most uniform passes — one cross-cut per row, then straight cuts between the pieces in that row. This is the friendliest option for a hand knife or guillotine, at the cost of a little more leftover film. Best when you are cutting by hand and want simple, predictable cuts.
Both modes respect grain-locked orientation and your wrap-allowance and gap settings; only the arrangement strategy differs. A good workflow is to quote with Save material and, if you prefer simpler cutting, switch to Easy cutting and compare how much extra film it needs.
Wrap allowance and gap
Wrapping a surface usually needs a little extra film to fold over the edges. Set a wrap allowance (in millimetres) and CutBloom adds it to every edge of every panel, so the cut size — and the film total — reflects what you will actually cut, not just the visible face. The gap setting leaves a small empty margin between pieces for the blade and for handling, so neighbouring cuts do not run into each other. Both are optional; leave them at zero for an exact face-size estimate.
Roll length and leftover
If you enter the length of the roll you are buying, CutBloom shows how many rolls you need and draws the whole roll — including the empty leftover after the last piece — so you can see at a glance how much film is left over. It also warns when a single panel is longer than the roll, which cannot be cut from one piece. Leave roll length blank to treat the film as one continuous strip and simply read the length needed.
Estimating a full quote
Beyond film, a real job includes labour and consumables. Enter your film or roll price, labour (a flat amount or a rate per square metre) and any sub-materials, and CutBloom adds them into a clear quote breakdown with an optional 10% VAT line and a total. Because the film cost is driven by the actual nesting, switching packing mode or roll width updates the quote too — handy for comparing options before you bid.
Presets, cutting list and export
Save the sizes you use most as presets and add them to a job in one click. When you calculate, CutBloom also builds a cutting list — each panel's real cut size, quantity and grain — that you can follow at the bench. You can flip the layout between a horizontal and a vertical view, save it as a PNG image, or print the whole result (quote, cutting list and layout) for the site. Everything, including your presets and settings, is stored only in your browser.
