About PaperFrost

Papercraft is one of the most forgiving hobbies there is — a single sheet, a fold, and a little patience is enough to start. The friction is rarely the idea; it’s the fiddly bits in the middle: which paper weight to buy, what size square a model needs, whether a card will fit its envelope, and how much stock a batch will eat. PaperFrost is built to take that arithmetic off your table so you can get on with making.

Rather than long essays you have to wade through, the site is a set of small, single-purpose calculators, each aimed at one real task. The Paper Weight Converter moves between gsm and pounds for any grade. The Origami Square & Size Calculator cuts the largest square from a sheet and plans a model’s finished size. The Card & Envelope Size Calculator matches a card to its envelope and the blank to cut. The Paper Quantity Calculator works out how many sheets a project needs, the Booklet Imposition Calculator lays out a folded booklet, and the Quilling Strip Length Calculator matches strip length to coil size.

Alongside the calculators, the blog and learnsection explain the craft the tools rest on — how paper is measured, the folds and coils that start most projects, how to score a clean crease, and how to store paper so it stays flat. Every explanation is written from scratch by hand.

A few things worth stating plainly. PaperFrost is independent and not affiliated with any brand, supplier, or publisher. It is supported by advertising, which is how the tools stay free with no account required. The calculators are planning and checking aids: they show their working and round for readability, but for a job where precision matters — a print run, postage, or an exact fit — confirm the result against a real swatch or test piece. If a tool looks wrong, or there’s a calculator you wish existed, the contact page is the place to tell us.
