Why Werkmaß?

The whole flat, not single calculators

Online calculators usually answer one question for one wall. Werkmaß adds up all rooms and trades and splits the paint into tin sizes that are actually sold.

Easy to follow

Every formula is in the instructions and in the folder’s cheat sheet – with a worked example. You adjust default values such as coverage or waste to your products.

Honest and independent

No ads, no tracking, no product recommendations for commission. The consumption figures on your products always take precedence.

Frequently asked questions

What language are the products in?

The calculator and the PDF are in German. Labels and instructions are German; the numbers, units (metres, litres, square metres) and results are easy to follow without much German. Please only buy if that suits you.

Do I need an account or a subscription?

No. You buy once and receive the files via a download link. They are yours to keep.

Aren’t such calculators available for free?

For single questions, yes – for example wallpaper calculators from DIY stores. Werkmaß calculates several rooms and all trades together, deducts windows, doors and tiled areas, combines everything in a printable shopping list and works offline.

Does the calculator work on a phone?

On Android devices with Chrome or Firefox, yes. On iPhone and iPad, iOS only opens local HTML files as a preview without program functions – we recommend a computer there.

How accurate are the results?

As accurate as your measurements and the consumption figures you enter. Werkmaß always rounds rolls, packs and bags up and calculates with adjustable waste.

How quickly will I get the download?

Usually within 24 hours on working days, at the latest after two working days – by email to the address you entered in your order.

Can I return the product?

For digital content the right of withdrawal expires once we send the download link with your express consent. Details are in the information on the right of withdrawal. If something does not work, write to us – of course we fix defects.
