Finding the perfect phone wallet is about more than just colour — size matters. Too small and your phone won't fit; too large and it loses that sleek, slim feel you're after. This guide walks you through exactly how to choose the right phone wallet size so you get it right the first time.

Why Phone Wallet Sizing Is Different to Regular Wallets

Unlike traditional wallets, a phone wallet needs to accommodate your specific handset - and phone sizes vary significantly across brands and models. The right fit means your phone slides in snugly without forcing it, and the wallet closes cleanly over the top.

A wallet that's too tight can put pressure on your phone's camera or buttons. One that's too loose won't hold your phone securely. Getting the fit right matters for both function and longevity of the wallet itself.

Step 1: Measure Your Phone

Before anything else, grab a ruler and measure your phone's dimensions:

• Height — the length of your phone from top to bottom
• Width — the measurement across the face of your phone
• Depth — how thick your phone is (especially important if you use a case)

Important: measure with any case you plan to keep on the phone, as a case can add several millimetres to each dimension.

Step 2: Check the Wallet's Internal Dimensions

Each phone wallet will have an internal pocket size — this is the measurement that matters, not the external wallet dimensions. Look for a wallet where the internal pocket is a few millimetres larger than your phone on each side. This gives a secure hold without a forced fit.

Our Agatha Wallet Size Guide lists the exact internal dimensions for each Agatha size alongside a comprehensive compatibility chart — it's the easiest way to confirm your phone will fit before you order.

Step 3: Choose Your Size

The Agatha Phone Wallet comes in two sizes to suit the most popular handset ranges:

• 18cm — suited to smaller and mid-sized phones
• 20cm — designed for larger handsets and most phones with a case

Not sure which applies to your phone? The Agatha Wallet Size Guide has a full model-by-model compatibility list so you can find your exact phone and confirm the right size in seconds.

What If I'm Between Sizes?

If your phone sits right on the boundary between the two sizes, we recommend sizing up. A slightly roomier fit is more comfortable day-to-day and makes it easier to slide your phone in and out — especially important for phones with larger cameras or thick cases.

Card Capacity: Don't Forget the Extras

A phone wallet isn't just for your phone - it replaces your whole bag for everyday errands. Think about how many cards you carry and whether you need a note pocket. The Agatha holds cards, cash, and your phone all in one, so it's worth considering your full everyday carry when choosing.
