Aldi and Lidl both sell low-cost supermarket nappies for families looking to keep their little ones dry at a reasonable price. 

Included in Aldi's Mamia and Lidl's Lupilu range, these own-brand nappies are sold at almost identical prices, and both brands claim their products will keep your baby dry for 12 hours.

Aldi and Lidl also fill their shelves with almost matching nappy sizes but, despite the similarities, one of the brands does much better than the other in our tests.

Read on to find out how these two popular brands compare, or head straight to our list of the best disposable nappies across all the brands we've tested.

What do Aldi and Lidl nappies offer?

Aldi Mamia nappies and Lidl Lupilu nappies

Aldi Mamia Ultra-Fit Nappies

Aldi says its nappies have an ultra-dry air system with a fast-absorbing core to keep your baby dry for up to 12 hours. The nappies don’t contain any perfume, lotion or latex and are designed to be soft and breathable with a slim fit for free movement. Aldi's nappies are available in sizes one to six, and there are also plus sizes for extra absorbency.

Lidl Lupilu Nappies

Lidl claims its Lupilu nappies have magical air tubes with absorbent channels in the core to keep your baby dry for up to 12 hours (eight hours for the newborn range). They have soft fleece and an elasticated waistband for a comfortable fit. Its nappy range covers sizes one through to six, with three additional plus sizes.

Lidl also sells a sensitive range which the discount supermarket claims offers advanced comfort, fit and flexibility. These nappies come in sizes one to five.

How much do Aldi and Lidl nappies cost?

Pile of nappies

The cost of Aldi and Lidl nappies varies depending on the size you choose and the size of the pack, but it doesn't always make a massive difference to buy in bulk (aside from the convenience of not having to head to shops to buy more as regularly).

If you're sizing up or down, that usually changes the number of nappies you get in a packet, which can affect the price per nappy.
