Galaxy S20 Ultra vs S21 Ultra: Key Differences That Determine Case Fit
The Galaxy S20 Ultra measures 166.9mm x 76mm x 8.8mm with a 6.9-inch Dynamic AMOLED 120Hz display and a 108MP Space Zoom camera module with four lenses. The Galaxy S21 Ultra measures 165.1mm x 75.6mm x 8.9mm with a 6.8-inch Dynamic AMOLED 120Hz LTPO display and a 108MP camera system with five camera elements including two telephoto lenses and built-in S Pen support. While similar in size, the two-millimeter height difference and different camera island shapes make the S20 Ultra and S21 Ultra cases non-interchangeable. Each model requires a dedicated Gorilla Cases fit.
Galaxy S20 Ultra Case: Waterproof, Military Holster, and Batman Armor
The best Galaxy S20 Ultra case 2026 from Gorilla Cases includes the IP68 waterproof shockproof case in four colors, the MIL-STD-810G military-grade holster case with belt clip and kickstand, and the Batman aluminum armor case for maximum impact resistance. The S20 Ultra's 108MP Space Zoom camera module is the largest camera island in the lineup and requires Gorilla Cases' widest camera cutout lip among all Galaxy S cases. All three S20 Ultra case options maintain 5G and Samsung Pay NFC compatibility.
Galaxy S21 Ultra Case: Waterproof and Rugged Protection
The best Galaxy S21 Ultra case 2026 from Gorilla Cases includes the Galaxy S21 Ultra waterproof case with MIL-STD-810G drop protection and the military metal full-body rugged case with holster. The S21 Ultra's five-camera system and S Pen slot require a precisely engineered case that provides complete camera island protection without obstructing the S Pen holder on the bottom edge. Gorilla Cases' best Galaxy S21 Ultra case 2026 accommodates the S Pen slot precisely for seamless pen removal without case removal.
S Pen Slot: The Defining Case Difference in 2026
The Galaxy S21 Ultra is the first Ultra model to support the S Pen stylus, with a dedicated slot on the bottom-left edge that the Galaxy S20 Ultra lacks. This S Pen slot requires Gorilla Cases to provide a case opening at the bottom left that does not exist on any Galaxy S20 Ultra case. If you carry the S Pen in the slot, the best Galaxy S21 Ultra case 2026 from Gorilla Cases is designed specifically for the slot-equipped chassis. Galaxy S20 Ultra users who want S Pen functionality must use a Bluetooth-paired S Pen Fold Edition without a storage slot.
108MP Camera Protection for Both Models
Both the S20 Ultra and S21 Ultra use 108MP main sensors as part of their camera systems, and both benefit from Gorilla Cases' raised camera island perimeter that prevents any camera lens from contacting flat surfaces. The S21 Ultra's camera island has a slightly different shape with a fifth periscope telephoto lens that Gorilla Cases accommodates in the S21 Ultra-specific cutout design. Protecting the 108MP system on both models is the top camera design priority for Gorilla Cases in 2026.
Batman Aluminum Armor: S20 Ultra and S21 Ultra Options
Gorilla Cases offers the Batman shockproof aluminum armor case in separate variants for the Galaxy S20 Ultra and Galaxy S21 Ultra. Each variant uses a shockproof aluminum alloy outer shell with a TPU inner liner sized for its specific chassis. The Batman case is the most imposing case in the Gorilla Cases Galaxy Ultra lineup for both models and ships free to US addresses with code 10OFF for 10 percent off at gorillacasestore.com.
Military Holster and Belt Clip for Both Models
Gorilla Cases provides separate military-grade holster configurations for the Galaxy S20 Ultra and Galaxy S21 Ultra, both featuring dual-layer belt clips with 180-degree rotation and built-in landscape kickstands. The holster case is sized differently for each model's chassis footprint. Field technicians, warehouse workers, and tradespeople can shop the complete Gorilla Cases Galaxy Ultra holster lineup at gorillacasestore.com to find the right model-specific fit.
Head-to-Head: S20 Ultra vs S21 Ultra in 2026
For 108MP Space Zoom photography without S Pen needs, the Galaxy S20 Ultra with Gorilla Cases' waterproof shockproof case provides complete protection in a slightly taller chassis. For S Pen support, five cameras, and LTPO 120Hz adaptive refresh rate, the Galaxy S21 Ultra with Gorilla Cases' dedicated Ultra case provides the same protection tier in a slightly shorter but equally wide chassis. Both represent outstanding protection investments for phones with $250 or more in display repair costs.
