The iPhone 13 and iPhone 13 Pro Max are two of the most popular iPhones in active use in 2026: the iPhone 13 for its compact mainstream appeal and the iPhone 13 Pro Max for its large display and pro camera capabilities. Both are outstanding phones — but they are different enough in size, camera system, and user profile that the best case for each in 2026 is not the same. This guide gives you the direct comparison.
Quick Verdict: Best Case for Each in 2026
The best iPhone 13 case in 2026 is the Gorilla Cases iPhone 13 Waterproof Case With Built-In Screen Protector at $39.00 — IP68 waterproofing, MIL-STD-810G drop protection, and an integrated screen protector for Apple's most popular mainstream iPhone.
The best iPhone 13 Pro Max case in 2026 is the Gorilla Cases iPhone 13 Pro Max Waterproof Case at $41.00 — IP68 waterproofing and MIL-STD-810G protection scaled to the large 6.7-inch Super Retina XDR ProMotion display and triple camera Pro system.
Size and Weight Comparison
The iPhone 13 has a 6.1-inch Super Retina XDR OLED display, making it a comfortable mainstream-size phone for one-handed use. The iPhone 13 Pro Max has a 6.7-inch Super Retina XDR ProMotion OLED display — Apple's largest iPhone display of the generation. The Pro Max is significantly heavier and larger, which changes the drop risk profile: a larger, heavier phone generates more impact force in a drop, and the display costs more to repair. The Gorilla Cases waterproof cases are sized specifically for each device and are not interchangeable.
Camera Comparison: iPhone 13 vs iPhone 13 Pro Max
The iPhone 13 has a dual 12MP camera system (main and ultrawide). The iPhone 13 Pro Max has a triple 12MP camera system (main, ultrawide, and 3x optical zoom telephoto) plus a LiDAR scanner. For photography enthusiasts and content creators, the Pro Max is the clearly superior camera phone. For most users, the iPhone 13 camera is more than sufficient. Both Gorilla Cases waterproof options protect their respective camera systems with raised camera rings and clear optical windows.
ProMotion Display: Why the Pro Max Screen Matters More
The iPhone 13 Pro Max has Apple's ProMotion AMOLED display with 120Hz adaptive refresh — a feature not on the standard iPhone 13 (which runs at 60Hz). ProMotion produces noticeably smoother scrolling. The ProMotion display represents a premium component with higher repair costs, making screen protection more valuable for the Pro Max than for the standard iPhone 13.
Case Recommendations by Use Type
