The Thinnest Phone Cases You Can Buy

How We Measure "Thinnest"

Case thickness is measured at the back panel, the flat area that covers the rear glass of the phone. This number does not include the camera lip, which protrudes above the back panel to protect the camera module, or the edge thickness, which is often slightly greater than the back panel to wrap around the phone's sides. All measurements in this guide refer to back panel thickness as published by the manufacturer and verified against third-party reviews where available.

Weight is listed alongside thickness because a case can be thin but surprisingly heavy if it uses dense materials. The lightest cases on this list weigh around 8 grams, which is roughly the weight of two nickels. For context, the iPhone 17 Pro weighs approximately 194 grams, so an 8-gram case adds about 4 percent to the phone's total weight.

The Thinnest Cases Ranked

1. Peel Super Thin Case (0.35 mm, ~10 g)

Peel's Super Thin Case remains the benchmark for absolute minimum thickness. At 0.35 mm, the polypropylene shell is so thin that it flexes noticeably when you press on the back panel. The material is semi-translucent, allowing the phone's color and finish to show through with a frosted, diffused appearance. It feels like barely anything between your fingers and the phone itself.

The engineering challenge at 0.35 mm is structural integrity. PP at this thickness cannot withstand strong flex forces, so removing the case requires gentle technique rather than prying it off from a corner. The camera lip is roughly 0.3 mm, enough to prevent lens contact with flat surfaces but not enough to survive a face-up drop onto uneven ground. There is no raised screen lip. There are no MagSafe magnets.

What you get is pure scratch prevention and a near-invisible aesthetic. The Peel Super Thin is for people who would rather have no case at all but want the peace of mind that their phone's back glass will not get micro-scratched by keys, coins, or tabletop grit. At $29 to $35, you are paying for the precision engineering required to produce a functional case at this extreme thinness. Available for iPhone 17, 16, and 15 series, and Samsung Galaxy S26 and S25.

2. Totallee Super Thin (0.35 mm, ~10 g)

Totallee's Super Thin matches Peel on thickness and material. Both use polypropylene at 0.35 mm, and both weigh roughly 10 grams. The functional differences are minimal: Totallee's finish is very slightly smoother than Peel's, and Totallee puts no logo on the exterior of the case (Peel has a small engraved logo near the bottom). Both provide the same level of scratch-only protection with no drop absorption, no MagSafe, and no screen lip.

The choice between Peel and Totallee at this thickness tier comes down to color options, logo preference, and availability for your specific phone model. Totallee prices its Super Thin at $35, matching Peel. Available for recent iPhone and select Samsung Galaxy models.

3. Spigen Air Skin (0.7 mm, ~14 g)

Spigen's Air Skin doubles the thickness of Peel and Totallee but costs a third of the price. At 0.7 mm, it is still noticeably thinner than most "slim" cases, and the semi-rigid material feels more substantial than PP without approaching the bulk of a standard case. The Air Skin uses a polypropylene-like material with slightly more rigidity than pure PP, giving it better shape retention and a more confident snap-on fit.

The camera lip is more pronounced than the Peel's at roughly 0.5 mm, and there is a very slight raised edge around the screen. No MagSafe magnets. The matte finish resists fingerprints well. At $13 to $16, the Air Skin is the cheapest way to enter ultra-thin territory from a reputable brand. It is not as thin as a Peel, but it costs $15 to $20 less and provides slightly more structure. Available for iPhone, Samsung Galaxy, and Google Pixel models.

4. Thinborne Aramid Case (0.65 mm, ~16 g)

Thinborne's aramid fiber case is the thinnest option that uses a genuinely strong material. At 0.65 mm, it is thicker than PP cases from Peel and Totallee but thinner than PITAKA's MagEZ. The aramid fiber weave provides structural strength that PP cannot match at any thickness, meaning this case resists scratching, flex cracking, and surface damage far better than polypropylene alternatives.

The real advantage of Thinborne at this thickness is that it includes MagSafe magnets, something no PP case at 0.35 mm can offer without adding bulk. The magnet array adds negligible thickness because it is embedded within the aramid weave itself. Camera lip is about 0.5 mm, and a slight screen lip is present. At $40 to $55, it is more expensive than Spigen's Air Skin but offers a fundamentally stronger material with magnetic compatibility. Available for iPhone and Samsung Galaxy models.

5. PITAKA MagEZ Case 5 (0.95 mm, ~20 g)

PITAKA's MagEZ Case 5 is the thickest entry on this list, but it earns its place because of what it delivers within its 0.95 mm profile. The 1500D fusion weave aramid fiber is the densest and strongest weave used in any consumer phone case. Built-in MagSafe magnets are stronger than those in Thinborne's thinner case, and the overall fit and finish represents the current state of the art in slim case engineering.

At 0.95 mm, the MagEZ 5 is roughly three times thicker than a Peel, but in absolute terms it is still less than 1 mm, thinner than a credit card. The camera lip at 0.8 mm and screen lip at 0.5 mm are the most substantial on this list, providing genuine protection for the two most vulnerable surfaces. At $50 to $70, it is the most expensive option here, but it is also the only one that combines thinness, strength, and full MagSafe support at a level suitable for daily use in any environment. Available for iPhone, Samsung Galaxy, and Google Pixel.

What You Give Up at 0.35 mm

Going to the absolute thinnest cases requires accepting specific limitations that are worth understanding in concrete terms rather than vague warnings.

Zero drop protection. A 0.35 mm PP case will not absorb any impact energy from a drop. If your phone falls face-down from waist height onto concrete, the result will be the same as if you dropped it with no case at all. The case prevents the back glass from contacting the ground directly, which may prevent a back-glass crack in some scenarios, but it does nothing for edge impacts or face-down falls.

PP scratches easily. Polypropylene is a soft material. The case itself will develop visible scratches within weeks of daily use, especially if your phone shares a pocket with keys, coins, or other hard objects. These scratches do not affect the case's protective function (it still prevents the phone's surface from getting scratched), but they make the case look worn quickly.

No MagSafe. There is no way to embed magnetic arrays in a 0.35 mm PP case without adding thickness. If you use MagSafe chargers, wallets, or car mounts, you will need to add a separate magnetic ring (which adds 0.5 to 1.0 mm and defeats the thinness purpose) or choose a thicker case with built-in magnets.

Minimal camera protection. The camera lip on ultra-thin cases is barely there. Setting your phone face-up on a sandy beach, a gravel path, or any surface with loose particulate risks scratching the camera lens, because the lip is too thin to keep debris away from the lens surface.

Case lifespan is shorter. PP cases at 0.35 mm become brittle over time, especially with repeated removal and reinstallation. Expect to replace a PP case every 4 to 8 months if you remove it regularly for cleaning or switching. Aramid cases at 0.65 mm and above last significantly longer, typically 12 to 18 months or more.

Is Ultra-Thin Worth It?

Ultra-thin cases serve a specific audience: people who actively dislike the feel of a case and want the minimum possible barrier between their hand and the phone. For these users, a Peel or Totallee at 0.35 mm provides just enough coverage to prevent cosmetic damage from daily carry without changing the phone's fundamental in-hand experience. The case is there to stop scratches from pocket debris, table surfaces, and incidental contact, not to survive drops.

For most other users, the sweet spot is slightly thicker. A Spigen Air Skin at 0.7 mm or a Thinborne at 0.65 mm provides a noticeably more secure feel in hand while adding structure that PP cases lack. The thickness difference between 0.35 mm and 0.65 mm is imperceptible to most hands, but the difference in material strength, magnet support, and longevity is substantial.

If you are considering an ultra-thin case for the first time, the Spigen Air Skin at $14 is the lowest-risk way to test the experience. If you find it too thick and want to go thinner, step down to a Peel or Totallee. But many people who buy the Air Skin as a stepping stone find that it is thin enough to satisfy their desire for a minimal case without the durability compromises of 0.35 mm PP.
