Ever ordered custom mugs and they felt too small?
Or worse too big and awkward?
Here’s the twist
The “perfect mug size” isn’t just about how much coffee it holds. It’s about usability, branding, and customer perception.
What most business owners don’t realise is this:
Mug size directly impacts:
- Daily usage
- Print visibility
- Comfort
- Perceived value
Choose wrong and your mugs sit in cupboards.
Choose right and they become daily brand reminders.
Let’s break it down properly.
What Is the Perfect Mug Size?
The perfect mug size depends on the purpose but the most popular standard size is:
11oz (325ml)
This is considered the classic, everyday mug size in the UK and globally.
Other common sizes include:
- 8oz (240ml) – Smaller tea/coffee mugs
- 11oz (325ml) – Standard office mug
- 15oz (440ml) – Large coffee lovers’ mug
- 16oz+ – Travel-style or oversized mugs
For most businesses, 11oz is the safest and most versatile choice.
