Size & Fit
Which size am I?
Ukoala's multi-wear bags are built around the same patented U-shaped strap, with size options that vary by style. Use the three height bands below as a starting point, then check the product page for the sizes and dimensions available for your bag. If you're between two sizes and the style offers Standard, choose Standard.
4'9" – 5'2"
Lightest, lowest-profile carry. Sits close on a shorter torso so the bag never overwhelms your frame.
5'3" – 5'9"
The do-everything size. Fits about 80% of customers and carries every modular pocket layout we make.
5'10" and up
Longest strap geometry and the most room. Built for a taller torso and bigger daily loads.
How to choose
When in doubt, go Standard. It fits about 80% of customers on the core styles that offer it, making it the most versatile choice when you're between two sizes. Choose Compact for the smallest profile, and Expanded for more room or a taller torso.
Still unsure? Check the published dimensions on the product page, or send us your height, preferred carry position, and what you plan to carry. We'll help you narrow it down before you order.
How to measure your height
- Stand against a wall in flat shoes — or barefoot — with your heels together.
- Look straight ahead and keep your head level so you don't add height.
- Mark the wall at the top of your head, then measure from the floor to the mark.
- Match that number to a band below. Between two? Size up to Standard.
Big Foot sizes
The Big Foot Double and Triple-Expanded models run larger than the three sizes above. Exact height-to-size guidance for those is coming soon — check the dimensions on each Big Foot product page in the meantime, or reach out and we'll help you choose.
