Updated: July 2026

Welcome

One of the first questions every new Maileg collector asks is:

"How big are the different Maileg Mice?"

With Babies, Little Brothers, Little Sisters, Big Brothers, Big Sisters, Mum, Dad, Grandma and Grandpa, it can be difficult to picture how they all compare.

The good news is that Maileg has created a beautifully scaled Mouse family where each character has its own place, personality and purpose.

This guide explains the different Mouse sizes, how they compare, which accessories fit and how to choose the right Mouse for your collection.

Meet the Maileg Mouse Family

Although every Mouse has its own unique personality, they are all designed to work together as one family.

From tiny Baby Mice sleeping in matchboxes to Grandma and Grandpa relaxing in their favourite chairs, every size adds another chapter to your Maileg story.

Mouse Size Comparison

Mouse Approximate Height Best For
Baby Mouse 8 cm Nurseries, cots and tiny adventures
Little Brother & Little Sister 11 cm Matchbox beds, tricycles and imaginative play
Big Brother & Big Sister 13 cm Scooters, tricycles and active adventures
Mum & Dad 15 cm Family homes and furniture
Grandma & Grandpa 15–16 cm Completing the Mouse family

Approximate heights may vary slightly between collections as every Maileg piece is lovingly handmade.

Baby Mouse

Approximate height: 8 cm

The Baby Mouse is the smallest member of the Mouse family.

Often tucked into a cosy sleeping bag or tiny cot, Baby Mice are perfect for creating nursery scenes and family stories.

Their tiny size makes them wonderfully charming while still fitting beautifully with the wider Mouse family.

Little Brother & Little Sister

Approximate height: 11 cm

These are among the most popular Maileg characters.

Little Brother and Little Sister fit beautifully into matchbox beds and work perfectly with many of Maileg's iconic accessories including tricycles, beach sets, camping gear and seasonal collections.

If you're buying your very first Maileg Mouse, this is often where we recommend starting.

Big Brother & Big Sister

Approximate height: 13 cm

Big Brother and Big Sister share the same adventurous spirit but have slightly taller proportions.

They're perfectly suited to scooters, tricycles, skis and many outdoor accessories, making them favourites for imaginative storytelling.

Mum & Dad

Approximate height: 15 cm

Mum and Dad complete the heart of the Mouse family.

They're designed to suit family homes and larger furniture while bringing warmth and personality to every Mouse House.

Whether they're preparing dinner, reading a bedtime story or enjoying a quiet cup of tea, Mum and Dad help bring everyday family life into the Maileg world.

Grandma & Grandpa

Approximate height: 15–16 cm

Grandma and Grandpa are similar in size to Mum and Dad but feature their own distinctive clothing, personalities and timeless charm.

No Mouse family feels quite complete without them.

Which Accessories Fit?

One of the wonderful things about Maileg is that many accessories are designed to work across multiple Mouse sizes.

Little Brother and Little Sister enjoy the widest range of accessories, while Big Brother and Big Sister have their own adventure-themed collection.

Family furniture is designed for Mum, Dad, Grandma and Grandpa, but many collectors happily mix different pieces to create homes that feel unique and personal.

There really are no rules.

Buy the pieces you love and enjoy building your own little world.

Which Mouse Should I Buy First?

If you're just beginning your Maileg journey, we usually recommend starting with either:

  • Little Brother
  • Little Sister
  • Big Brother
  • Big Sister

These characters offer the greatest variety of compatible accessories and make it easy to expand your collection over time.

Of course, the best Mouse is always the one that makes you smile.
