How we test nappies

We find out which nappies absorb quickly, avoid leakages, stay dry on the surface and stay secure on your bundle of joy.

Stop the leaks

Our starting point for testing nappies is what you, as a parent, want out of a nappy for your child. So our specialist CHOICE Consumer Insights research team designed a survey which went out to 500 parents of children aged under two.

Here's what you told us: when it comes to what's very important in a nappy, 75% of you are looking for a nappy that avoids leakages, and 72% find it very important that a nappy is absorbent. This has helped to shape our nappy testing.  

We test 46 types of nappies from brands including Babylove, Huggies, Naty by Nature, Coles, Mamia, Pampers and more in our disposable nappy reviews.

Our expert testers

For our test, we bought as many brands as possible within the newborn, infant and crawler sized nappies and sent them to a laboratory for testing. In-house, we work out the value for money of each product by determining how much it costs per nappy (based on the largest pack size available). We also take a look at the labelling claims.

How we choose what we test

With most of our product testing, our aim is to test the most popular models on the market and what you're most likely to see in the retailers. In the case of nappies our buyers purchased all the products they could find on the supermarket shelves in the newborn, infant and crawler categories.

How we test


Using synthetic urine, gushes of the liquid are dosed into the centre of the nappy using a pump. For newborn nappies each gush is 30mL, for infant nappies it's 40mL and for crawler nappies it's 50mL. This simulates a child wearing the nappy overnight. We measure the amount of time it takes for the liquid to disappear. This is repeated four times with a five minute gap between each gush. The total time taken for all four gushes to be absorbed is the absorption speed.


This is a visual assessment where we check if any leaks come out the side of the nappy.


Five minutes after the last gush from the absorption test, six pre-weighed dry filter papers are placed on the wet nappy and held down for 30 seconds. The filter paper is then removed and weighed. Ideally, the filter paper should remain relatively dry.

Velcro strength

We measure the force required to open the velcro tabs.

Test criteria explained

The overall score is made up of:

  • Absorption (40%)
  • Leakage (30%)
  • Rewet (20%)
  • Velcro strength (10%)
