⚡ The short answer
A phone case is never universal: it is molded for a specific model, and the camera module cutouts, not the casing dimensions, determine compatibility. Two phones can share the same 146.7 × 71.5 mm dimensions and still be incompatible. Before ordering a SpongeBob case, find the exact model name in your settings (not the brand, not the year of purchase), then check that it appears in the product page's dropdown menu. Our cases are available for major iPhone generations and common Android ranges, in soft silicone for €17.90 and a reinforced version for €27.90.

There's an unpleasant moment many people know: the package arrives, you take out the case, it looks great, and it just won't fit. Or worse, it fits, but the camera module sticks out half a centimeter next to the hole. In almost all cases, this isn't a manufacturing defect. It's a confusion between two similar-looking models, and this confusion is perfectly avoidable in thirty seconds.
The problem stems from a linguistic habit. We say "I have an iPhone 14" or "I have a recent Samsung," while the manufacturer sells four variants of the same generation, with different camera modules and widths that vary by two millimeters. A case, however, is molded to only one of these templates. There is no such thing as an "iPhone 14 all versions" case, and a store that promises you one will sell you a case that's too loose.
This article settles the matter once and for all. First, we'll see why the camera module dictates everything, then how to read your device's exact name, then the model pairs that trap the most people, and finally, how the material affects the adjustment tolerance. If you're still hesitating between a soft case and a hard case, our soft or hard SpongeBob case comparison addresses this question in detail, and the general guide to SpongeBob cases reviews all available visuals.
Why a case is linked to a specific model
A case must do three things simultaneously: conform to the chassis's contours, allow camera lenses to pass through unobstructed, and leave the charging port, speakers, and buttons clear. These three constraints rarely fall in the same place from one generation to the next.
The camera module dictates more than the dimensions
This is the point everyone underestimates. On recent iPhones, the camera module occupies a top-left square that has grown in size almost every generation. Two devices can have the exact same height and width, yet their camera cutouts are neither the same size nor in the same position. If you force a case designed for the previous generation, the wide-angle lens ends up half-covered by plastic: photos come out with a dark corner and a halo.
Thickness changes silicone tension
Between an iPhone 13 (7.65 mm) and an iPhone 14 (7.80 mm), the difference is fifteen hundredths of a millimeter. On a hard case, this gap is enough to prevent full clipping: the case holds on three corners and dislodges on the fourth. On a silicone case, it will fit, but it will be stretched permanently and will deform after a few weeks.
Buttons don't align to the same millimeter
On many Android lines, the power button and volume rocker change height from one year to the next. A case shifted by three millimeters is still usable, but you're pressing the silicone instead of the button: the travel becomes soft, and you end up pressing twice. This is the kind of detail you don't see in a product photo but experience every day.
Find your phone's exact model in 30 seconds
Don't rely on the box, the seller, or your memory. The device knows its own name; you just need to read it.
On iPhone
Open Settings, then General, then About. The first line, "Model Name," displays the full label: "iPhone 14 Pro," "iPhone 15 Plus," etc. This is the exact label you need to find in the product page's dropdown menu. Just below it, the "Model Number" line starts with an A followed by four digits (A2650, A2890...): this is the most reliable reference of all, one you can compare directly if any doubt remains.
On Android
Open Settings, scroll down to About phone. You'll find "Model name" and "Model number." For Samsung, this number starts with SM- (e.g., SM-S911B for a Galaxy S23). For Xiaomi and Redmi, the commercial name and technical name often differ: this is precisely where ordering errors arise.
Physical verification
If the phone no longer turns on, the engraving on the back provides the answer. On iPhones, the A#### number is inscribed in tiny print below the regulatory notice. On most Androids, it's found under the battery or on the SIM tray. As a last resort, measure the casing with a ruler: length, width, thickness, in millimeters, device bare and without a case.
💡 Did you know?
The "mini" and "Plus" of the same generation share no case parts. An iPhone 13 mini is 131.5 mm tall, while the standard iPhone 13 is 146.7 mm: a fifteen-millimeter difference, equivalent to a finger joint. These are two entirely distinct products, despite an almost identical name.
Most popular SpongeBob cases
Four designs available for major iPhone generations and common Android ranges.
iPhone compatibility: generation-by-generation pitfalls
Here are the most common confusions in product returns, and why they occur.
iPhone 12 and iPhone 13: the classic trap
Both measure 146.7 × 71.5 mm. The iPhone 12 is 7.40 mm thick, the iPhone 13 is 7.65 mm. One might think they are interchangeable, except that the iPhone 13's camera module is significantly larger and its two lenses are arranged diagonally instead of being stacked vertically. An iPhone 12 case placed on an iPhone 13 will obscure one of the two lenses. The reverse leaves a visible gap.
iPhone 13 and iPhone 14: same size, different cutouts
Again, 146.7 × 71.5 mm on both sides, with 7.65 mm versus 7.80 mm thickness. The camera cutouts are similar but not identical, and the fifteen hundredths of a millimeter in thickness are enough to make clipping a hard case uncomfortable. Some very elastic soft cases can fit both models, but it's never guaranteed, and the fit remains poor.
Pro versions are a different product
The iPhone 14 Pro measures 147.5 × 71.5 × 7.85 mm, compared to 146.7 × 71.5 × 7.80 mm for the standard iPhone 14. Eight tenths of a millimeter in height, and especially a much larger camera module. No case is common to both. The same applies to the 13/13 Pro and 15/15 Pro pairs.
iPhone 15 and iPhone 16
Both share 147.6 × 71.6 × 7.80 mm. This is the only recent pair where a soft case fits without issue from one model to the other, provided the camera cutout is wide enough. However, the Action button and microphone positions change: check that the side openings match before committing.
The reflex that solves everything
On each product page, the "Model" dropdown list only accepts references that are actually manufactured. If your exact model name isn't listed, it means the case doesn't exist for that device — and not that you should choose "the closest." In this case, an accessory that doesn't depend on the model, such as a SpongeBob keychain or a mouse pad, remains a risk-free alternative.
Android: Samsung, Xiaomi, and others
The Android world complicates things for one specific reason: the same commercial name can cover multiple technical references depending on the region of sale.
Samsung: read the SM- reference
A Galaxy S23 sold in Europe has a different SM- reference than the same phone sold elsewhere, but the chassis is identical, and the cases are compatible. However, a Galaxy S23 and a Galaxy S23 Ultra have nothing in common: the Ultra is more than a centimeter taller and its back is curved. The A-series (A34, A54...) follows its own dimension logic, unrelated to the S-series of the same year.
Xiaomi and Redmi: beware of twin names
This is where errors are most frequent. A Redmi Note and a Redmi Note Pro of the same generation have almost identical names but neither the same dimensions nor the same camera module. The only reliable method is to check the full model number in the settings, without relying on the name displayed on the box.
When a case doesn't exist for your model
Android ranges are too numerous to be all covered. If your device doesn't appear, you have two options: a universal transparent case on which you stick a SpongeBob sticker cut to the correct dimensions — our article on where to stick your stickers without damaging anything explains the technique — or a companion accessory like an AirPods case, which only depends on the earbud model.
🧠 Tip
Take a flat photo of your phone's back with a ruler next to it. When ordering, you can quickly check the camera module's position against the cutout shown on the product page. Two seconds of visual comparison save a ten-day return.
Silicone, TPU, or hard case: what's the difference
The material doesn't just change protection; it changes the adjustment tolerance, meaning the margin of error you can afford.
Soft silicone
Typical thickness of 1.2 to 1.8 mm, very elastic. It deforms to fit, absorbs small drops well, and doesn't scratch the chassis. Its tolerance is the widest of the lot: a few tenths of a millimeter difference go unnoticed. Its downside is that it loosens over time and attracts dust to the edges. Our soft cases start at €17.90.
TPU
A thermoplastic polyurethane, halfway between: stiffer than silicone, more flexible than hard plastic. It's the best compromise for everyday use, with slightly raised edges above the screen and lens. The tolerance remains good but less generous than pure silicone.
Hard case
Polycarbonate, 1 to 1.5 mm, no elasticity. This is what best renders prints: colors are clear, contours are sharp, SpongeBob's yellow pops without haze. In return, tolerance is zero. An approximate model simply won't clip. Our article on SpongeBob product printing details why the rendering differs so much depending on the material, and the materials guide applies the same logic to clothing.
| Case type | Thickness | Model tolerance | Wireless charging | Ideal for |
|---|---|---|---|---|
| Soft silicone | 1.2 to 1.8 mm | Wide | Yes | Daily use, short drops |
| TPU | 1.5 to 2 mm | Medium | Yes | Compromise protection and slimness |
| Rigid polycarbonate | 1 to 1.5 mm | None | Yes | Best printed visual rendering |
| Reinforced hybrid | 2.5 to 3.5 mm | None | Variable | Construction, sports, children |
Wireless charging, MagSafe, and printed cases
Induction charging passes through plastic, but not just any thickness. In practice, a case less than 3 mm thick poses no problem on a standard induction charger. Beyond that, power drops, and charging becomes slow or even stops.
What truly blocks it
Metal. A magnetic plate attached for a car mount, a metal ring, a bank card slipped into a card holder on the back: these elements disrupt induction and cause the device to heat up. If you use wireless charging, choose a simple case and keep the card holder separate — a separate SpongeBob wallet solves the problem without compromise.
MagSafe
iPhone's MagSafe magnets will pass through a non-magnetic case, but the attachment will be weak and the charger will slip. For proper hold, you need a case that integrates its own magnetic ring. A classic printed case will allow charging, just without the magnetic click.
Is the print heat resistant?
Yes. The heat generated by induction charging remains well below temperatures that would alter UV printing or sublimation. What damages a visual is rather repeated friction in a pocket with keys, and prolonged exposure to the sun behind a windshield.
To complete the protection
Three reinforced cases and matching earbud case.
The five most common ordering mistakes
1. Ordering by purchase year
“I bought it in 2023” says nothing about the model. Manufacturers sell previous generations for two to three years after their release. Only the label in the settings is authoritative.
2. Confusing Plus, Pro and Pro Max
These suffixes are not trim levels; they are different chassis. The Pro Max is the largest in the range, the Plus shares its size but not its camera block, and the Pro is standard size with an enlarged module.
3. Choosing "the closest model"
There is no "close" when it comes to phone cases. Either the label matches, or it doesn't.
4. Forgetting the screen protector already applied
A tempered glass film with glued edges can conflict with the edges of a rigid case: the film peels off at the corners after a few days. With a case with raised edges, choose a film with straight edges.
5. Neglecting the charging port cutout
If you use a reinforced or angled cable, check the width of the bottom opening. Some reinforced cases leave just enough clearance for an original cable and nothing more.
⚠️ Mistake to avoid
Never force a rigid case that resists. The typical breaking point is the lower corner: it cracks cleanly, and the phone ends up with a bare corner, precisely the area that takes the most impact. If three corners clip on and not the fourth, it's not the right model. Remove it and check your reference.
Delivery and lead times
All cases ship under the same conditions as the rest of the store: €5.90 shipping in France and the European Union, free delivery from €60 purchase, and €7 outside the European Union. Delivery time is 7 to 14 business days.
A single case is usually not enough to reach the free delivery threshold. If you want to cross it without buying randomly, articles on gifts under €20, on the actual content of gift sets and on prices by category will help you compose a coherent order. Our complete guide to merchandise provides the overview.
Frequently asked questions
Will an iPhone 13 case fit an iPhone 14?
The external dimensions are identical (146.7 × 71.5 mm), but the iPhone 14 is 0.15 mm thicker and the camera cutouts differ. A very elastic soft case might fit, a rigid case will not. This is not official compatibility and the fit will be approximate.
How do I know if I have a Pro model?
Settings, General, About: the "Model Name" line shows the full suffix. Visually, Pro versions have three camera lenses instead of two and a steel frame rather than aluminum.
Does the case prevent wireless charging?
No, as long as it remains under 3 mm thick and no metal parts are embedded in the case. A magnetic plate for a car mount, however, will block charging and cause the device to heat up.
What if my model is not offered?
Do not choose a similar model. Opt for a universal clear case customized with a SpongeBob sticker, or for a phone-independent accessory like a keychain.
Do soft cases yellow?
Transparent silicones yellow with UV and sebum contact, usually after six to twelve months. Cases printed on a colored background do not show this defect since the support is not translucent.
How do I clean a printed case?
Warm water and mild soap, microfiber cloth, air dry. No alcohol or acetone, which attack the print varnish. The same logic as for the rest of the store, detailed in our maintenance guide.
Does a case really protect against a fall?
From a fall of less than one meter onto a flat surface, yes, in the vast majority of cases. On a curb corner or from over one and a half meters, a thin case is not enough: a reinforced version with raised edges of 2.5 to 3.5 mm is needed.
Can I put one case on top of another?
No. Superimposition creates pressure points that deform buttons, block heat dissipation, and prevent wireless charging. Only one case, adapted to the correct model.
In summary
Case compatibility hinges on a single piece of information: the exact model label, found in the device settings and nowhere else. Neither the purchase year, nor the brand, nor visual resemblance replaces this thirty-second check. Once the correct model is identified, the choice comes down to taste and material: soft silicone for tolerance and softness, rigid for a striking visual, reinforced if the device has busy days. That's all there is to remember before bringing a bit of Bikini Bottom into your pocket.
