This overall score is made up of disintegration time (30%), softness (30%), separation (tear) force (20%) and puncture (strength) force (20%).

We measure the ease of separating the toilet tissue at the perforation. The easier it is for toilet paper to tear, the better.

We assess the strength of the toilet paper by testing its resistance to puncturing. In this test a higher force is the most desirable result, meaning your finger is less likely to go through the paper.

We time how quickly the toilet paper disintegrates. The faster the better - you want your toilet paper to break up quickly as it moves through sewage, making it less likely to block pipes. The quickest takes just over a minute to disintegrate while the longest takes just over 16 minutes to disintegrate.

In this test we assess how soft the toilet paper is. This is a subjective assessment conducted by a panel of five people.

We recommend toilet paper that scores at least 80% overall.

'Tested model' means you ought to be able to find this toilet paper in retailers (or in a very few cases, online). We check availability every time we test.

This is the price we paid at the time of testing. Price is per pack, and will vary depending on the size of the pack you buy.

This is based on the pack size tested, but will vary depending on pack size and special offers. Check the unit pricing on shelves for the best value for money pack size.

Toilet paper generally ranges from two-ply to four-ply. This simply refers to the number of layers of paper used. Generally the higher the ply count, the thicker, softer, stronger and more absorbent the toilet paper should be.

The Program for the Endorsement of Forest Certification (PEFC) is an international organisation that works to promote sustainable forest management.

FSC (Forest Stewardship Council) is an international, non-profit organisation that promotes responsible forest management. It achieves this by setting standards on forest products with a certification process. You'll find the FSC tree-tick logo on many toilet paper packs, but if you take a closer look at the fine print you'll notice there are three classifications to the label – FSC Mix, FSC Recycled, FSC 100%.
