1. How to Find Your iPhone Model
Identifying your iPhone model ensures compatibility with protective cases. Here are the most reliable ways to check:
Check via iPhone Settings (Recommended)
- Open the Settings app.
- Tap General > About.
- Look for Model Name (e.g., iPhone 15 Pro Max).
Check the Original Packaging
Look at the back or side of your iPhone box. The Model Name or number is usually listed clearly (e.g., iPhone 14 Pro).
Check the Back of the Device (For Older iPhones)
If you have an iPhone 8 or earlier, you’ll find the model number laser-etched in small text near the bottom of the back.

Why It Matters for Your Case
Different iPhone models (Standard, Pro, Pro Max) vary in size, camera layout, and button placement. Choosing the exact model (e.g., “iPhone 15 Pro” instead of “iPhone 15”) ensures a perfect fit, especially for waterproof or rugged cases where camera alignment and seal precision are critical.
2. How to Find Your Samsung Model
Samsung offers a wide range of devices, including the Galaxy S, A, and Z Fold/Flip series, as well as different sizes within the same generation (e.g., S23 vs. S23+ vs. S23 Ultra). Here’s how to identify your Samsung model:
Check in Settings (Quickest Method)
- Open the Settings app.
- Scroll to About phone (or a similar option).
- You’ll see a field labeled Model Name or Model Number (e.g., SM-S918B/DS = Galaxy S23 Ultra).
Check the Device Itself or the SIM Tray
- On some models, you can find the model number:
- Printed on a sticker (behind the battery on older phones)
- Engraved near the SIM tray or inside it
Use Dial Code to Find IMEI
Dial *#06# In the phone app to display the IMEI and Serial Number.
These can help verify the device model using Samsung’s support site or tools.
Why It Matters for Your Case
Samsung models differ in:
- Screen size and dimensions
- Camera bump size (especially on Ultra models)
- S Pen slot (Ultra models only)
- Fold/Flip hinge structures
Knowing your full model name or code is essential for selecting a Samsung case that fits securely and protects your device properly.
3. How to Find Your Apple Watch Model
Apple Watch sizes (40mm, 41mm, 44mm, 45mm, 49mm) and versions (Series, SE, Ultra) significantly affect case compatibility.
Check on the Watch Itself
- Press the Digital Crown to open apps.
- Open Settings > General > About.
- Scroll down to find the Model and Serial Number.
Check via Your Paired iPhone
- Open the Watch app.
- Tap My Watch > General > About.
- Tap the Model field to view the full Model Name (e.g., Apple Watch Ultra 2 GPS + Cellular, 49mm).
Check the Physical Watch (Laser Engraving)
- For Series 1 and newer: Remove the band and look inside the band slot near the Digital Crown.
- For 1st generation models: The model is etched around the circular back sensor area.

Why It Matters for Your Case
Even within the same generation, Apple Watch sizes are not cross-compatible.
Ultra models have flat screens, side rails, and different button layouts. Choosing the exact series + size + version ensures the Apple watch case doesn’t block buttons or sensors and fits tightly for water/dust resistance.
Summary
The right phone case provides the right protection. Before purchasing a case, double-check the product name and description to ensure compatibility.
