Stencil & Vinyl Calculators

Vinyl and stencil crafts have grown rapidly in the UK thanks to affordable cutting machines from Cricut and Silhouette, which turn digital designs into precisely cut adhesive vinyl, heat transfer vinyl (HTV) and stencil material. Whether you are personalising mugs, making car decals or creating wall art, knowing how much material to cut from your rolls is essential for avoiding waste. Our vinyl sheet calculator works in centimetres and accounts for roll width, design dimensions and spacing between cuts, while the material cost calculator helps you track spending per project from your roll price.

Heat transfer vinyl is one of the most popular products for UK crafters making personalised clothing, tote bags and cushion covers for craft fairs and online sales. Our heat press calculator provides temperature, time and pressure settings for different HTV types on various fabrics — cotton, polyester, and poly-cotton blends each need different heat and dwell times. Getting these settings wrong can cause peeling, scorching or dull colours. For sublimation printing, which is popular for mugs, coasters and polyester garments, the sublimation calculator helps you size your design to the substrate and estimate ink coverage.

Stencil making is another growing area, whether you are cutting reusable Mylar stencils for furniture painting, creating cake decorating stencils, or producing window frost designs. Our stencil size calculator adds the correct border allowance around your design for clean application and easy repositioning. The weeding area calculator estimates how long the fiddly weeding process will take based on design complexity and total area — useful for quoting custom orders. For scaling designs across different products, the decal size calculator maintains proportions so your artwork looks right whether it is going on a laptop, a car window or a shop sign. The transfer tape calculator then ensures you have enough tape to lift and position your weeded vinyl cleanly.
