The problem

Free calculators divide area and hope.

They ignore the pattern repeat, the match type, the doors, the windows and the wall that slopes. Too few rolls, and the reprint arrives in a different dye lot. Too many, and somebody pays for paper that never leaves the wrap. And no matter who places the order, the number is yours: you sold it, specced it, or measured it. The callback is yours too.

The deliverable

A plan your client keeps. A cut sheet your installer follows.

Every strip numbered in hanging order. Every piece marked with the roll it comes from and the order to cut it. Offcuts from doors go above windows: planned, not improvised. Exported as a PDF that carries your branding, ready for the client and the job site. You hand over a document, not a guess.

Built for

The design sells itself.
The execution is on you.

Wallpaper shops

Close the sale in one reply.

A client sends measurements, photos and a pattern they love. You reply in minutes with the exact quantity to order and a plan carrying your logo, not a rough guess and a disclaimer. No reorders, no returns, no apologies.

Interior designers

Place the pattern with intent.

Seams, centering, offsets, match type: your wallcovering spec becomes as precise as the rest of your drawings. The client sees a professional plan before a single roll is ordered, and the install looks like the render.

Installers

The math is done before the ladder is out.

Numbered strips, roll and cut order, offcuts planned above windows. Quote faster, cut with confidence.

The standard

Built like an instrument, not a calculator.

Every quantity is computed strip by strip: repeat, match type, seams, corners, openings, even the slope of an attic wall. The same rules a master installer works by, applied without fatigue, down to the sixteenth of an inch. What you see on screen is what lands on the wall: the drawing, the cut sheet, and the order always agree.

Questions

Straight answers.

How accurate is it?

Quantities are computed per strip from your wall geometry, pattern repeat and match type: the same arithmetic a careful installer does by hand, without the hand. Always verify measurements on site before ordering; that rule is printed on every export.

Will my clients see my branding?

Yes. The PDF and JPG exports carry your name and logo. What you hand over looks like your work, because it is.

Does it work for murals and custom prints?

Yes, standard murals and custom-size murals alike. You draw the room, then position and scale the artwork until it sits perfectly on the walls. What goes to print is exactly what fits the room. Pattern mode handles print-on-demand designs the same way: strips cut to exact length, totals in square feet or square meters. The order matches the wall, so the install matches the plan.

What happens after the trial?

If you are among the first 100 founding members, $12/month, locked for as long as your subscription stays active. After the founding spots are gone, the price is $19/month. Cancel in one click; your projects stay on your device.

I install for a living. Will this slow me down?

A full room takes about two minutes to enter. The cut sheet it returns saves you the hour you spend with a calculator and a pencil, and the roll you order “just in case”.
