🧮 Calculators

Margin calculator

Vehicle wrap calculator: metres off the roll, how the panels nest, and the hours

Power and wiring for illuminated signs: cable size, voltage drop and how many drivers

Roll-up banners with the two zones you never see: the part that rolls into the cassette and the strip under the top rail. Plus eye level and a resolution check at full size.

Work out how many full sheets you need and exactly how to cut them

Sell vinyl by the running metre: brand, type, colour, roll width and length. Works out which roll width costs you the least.

Split a wall print into strips: the seam where you want it, overlap for double cutting, and a hanging plan.

The sloping area, not the footprint. Plus ridge, gutter length and how much material to order.

The physics of the cable: how much voltage you lose over the distance, and how much the warm conductor adds.

Landed cost

Pipe runs and vessels added up, so you know the filling time and how much product to add.

Work out a price straight from a PDF

How many litres you really need, with the doors and windows taken off and the spreading rate from your own tin.

Per room, at the rate of work you choose yourself. Hours per visit, price per visit and price per month.

Bark, soil, gravel, grass seed, hedge plants and paving, worked out from the area you measured.

Work order calculator

Rent calculator

For beams, battens, skirting and profiles: not the metres, but the number of stock lengths, and how to cut them.
