Samsung launched the Galaxy S22 and Galaxy S22 Plus on the same day with the same camera island, the same Armor Aluminum frame and nearly identical marketing photos. That resemblance fools a lot of shoppers into buying the wrong case. The short answer: no, a Galaxy S22 case will not fit a Galaxy S22 Plus, and vice versa. The two phones differ by more than 11 mm in height and 5 mm in width, which is far outside the tolerance any case can absorb.
The size difference in hard numbers
These are the published dimensions for both models:
- Galaxy S22 (SM-S901): 6.1-inch display, 146.0 x 70.6 x 7.6 mm, 167 g
- Galaxy S22 Plus (SM-S906): 6.6-inch display, 157.4 x 75.8 x 7.6 mm, 195 g
The thickness is identical at 7.6 mm, which is why the two phones feel so similar in hand. But 11.4 mm of extra height and 5.2 mm of extra width mean a Plus phone simply will not seat into an S22 shell, and an S22 dropped into a Plus case will rattle loose the first time you set it down hard.
How to tell which model you actually own
Open Settings > About phone > Model number. A code beginning SM-S901 is the base Galaxy S22. SM-S906 is the S22 Plus. SM-S908 is the S22 Ultra, which is a completely different shape with a curved screen and an S Pen silo. The letter suffix after those digits (U, U1, B, E) refers to the regional carrier variant and does not change the physical dimensions, so any case listed for SM-S901 fits every S22 regardless of carrier.
If the phone will not power on, measure it. Anything close to 146 mm tall is the base model; 157 mm is the Plus.
What the base Galaxy S22 needs
At 167 g the S22 is one of the lighter flagships of its generation, and a lot of owners chose it specifically because it is compact. A bulky case undoes that. If you want to keep the small footprint, a slim frame with a clear back keeps the phone close to its original thickness while still lifting the camera ring off the table.
If protection matters more than bulk, the full-body holster option for the S22 adds a belt clip and a rotating kickstand, which is the format most trades and delivery drivers end up on.

What the Galaxy S22 Plus needs
The Plus is 195 g before you add anything. That extra mass matters on a drop, because impact energy scales with weight. A phone that is 17 percent heavier hits the ground harder, so the Plus benefits more from a case with genuine corner structure than the base model does.
Water is the other consideration. The S22 Plus carries an IP68 rating from the factory, but that rating is tested in fresh water and it degrades as seals age and as the phone takes knocks. A dedicated sealed case is the honest answer if you actually plan to take the phone into water rather than just survive a spill.

Screen protectors are not interchangeable either
Both phones use a flat display, which makes tempered glass easy to apply on either one. But the glass is cut to the panel, and the punch-hole camera and ultrasonic fingerprint sensor sit in different places relative to the edges. A Plus sheet on a base S22 will overhang the bezel and lift; a base sheet on a Plus leaves a visible strip of unprotected glass.
Buy the sheet that names your exact model. Samsung placed an ultrasonic in-display fingerprint reader on both phones, so use glass that states fingerprint compatibility — thicker or heavily tinted glass can slow ultrasonic reads.
What actually does carry over
A few accessories are genuinely shared between the two:
- Chargers and cables. Both use USB-C. The base S22 tops out at 25 W wired, the Plus at 45 W, so a 45 W brick benefits the Plus and is simply not used to its full rate by the base model.
- Camera lens protectors. Both phones use the same three-lens layout with the same spacing, so lens rings often list compatibility for both.
- Magnetic car mounts that grip the case rather than the phone, and universal vent mounts.
- Qi wireless chargers. Neither phone has built-in MagSafe-style magnets, so magnetic attachment depends entirely on the case you choose.
Frequently asked questions
Will a Galaxy S22 Ultra case fit either of these? No. The S22 Ultra is 163.3 x 77.9 x 8.9 mm with a curved display, squared-off corners and an S Pen slot. It shares nothing dimensionally with the other two.
Does an S21 case fit an S22? No. The Galaxy S21 is 151.7 x 71.2 x 7.9 mm — about 5.7 mm taller than the S22, with a different camera bump that wraps into the frame. The cutouts do not line up.
Do the S22 and S22 Plus use the same battery case? No. Battery cases are shaped to the exact chassis and to the USB-C port position, so they are model-specific.
Is the S22 Plus IP68 rating affected by adding a case? A case does not reduce the phone's own rating, but it also does not add to it. Only a purpose-built sealed case provides submersion protection beyond what the phone already has.
How do I confirm a case fits before ordering? Match the model number on the listing to the model number in Settings. If you are still unsure, reach out through the Contact page or call 978-797-0223 and we will confirm the cut.
The bottom line
The Galaxy S22 and S22 Plus look like siblings and are not. Check for SM-S901 versus SM-S906 before you buy anything that touches the body of the phone — case, glass, holster or battery pack. Chargers, lens rings and universal mounts are the only things you can safely share between them.
