⚡ The short answer
Most of our clothing sizes follow Asian sizing standards, which are smaller than French sizes. The default rule is to take one size larger than your usual size, and two sizes larger if you want an oversized fit. If in doubt between two sizes, always choose the larger one: a sweatshirt that's too tight stretches the print, while a loose sweatshirt is still wearable.
📑 In this guide
It's the number one reason for disappointment in any clothing store, regardless of license: the package arrives, the design is perfect, but the sweatshirt is one size too small.
This is almost never an ordering error. It's a difference in sizing standards that no one explains to you when you choose. This article is for that, and it applies to the entire catalog.
Why sizes seem small
A size M does not mean the same thing everywhere. The reference sizes used for manufacturing vary by market, and the difference between an Asian and a European standard is roughly one full size.
In practice: if you wear M in France, you'll need an L in this sizing standard. This isn't a manufacturing defect; it's a different convention—just like shoe sizes that are read differently depending on the country.
The consequence is simple and without exception: never order your usual size without checking.
💡 Did you know? The oversized look popular today works in your favor: with these garments, a size too large can be seen as a style choice, whereas a size too small is immediately noticeable. The asymmetry of risk therefore always leans the same way.
The sizing chart
To be used as a starting point, before checking the precise measurements indicated on the product page you are interested in.
| Your usual FR size | To order (regular fit) | To order (oversized fit) |
|---|---|---|
| XS | S | M |
| S | M | L |
| M | L | XL |
| L | XL | XXL |
| XL | XXL | XXXL if available |
Measure yourself in two minutes
If you're still hesitating, measuring will settle it in two minutes and avoid a return. You'll need a tape measure, or failing that, a garment you already like to wear.
The witness garment method is the most reliable and fastest. Take a sweatshirt that you find to be the right size, lay it flat, and measure the width from armpit to armpit. Multiply by two: you get the chest circumference of the garment, which can be directly compared to the measurement indicated on the product page.
Also measure the length, from the top of the shoulder to the bottom of the garment. This is the measurement most often forgotten, and the one that determines the silhouette: a sweatshirt that stops at the hip lengthens, a mid-thigh sweatshirt shortens.
⚠️ The most common mistake — Measuring yourself instead of measuring a garment. The body's chest circumference cannot be directly compared to that of a garment, which includes the necessary ease of movement. Always measure a garment against a garment.
Rules by category
The one-size difference is the general rule, but each product family has its own peculiarities.
Sweaters and hoodies
This is the category where the rule applies most strictly, and where errors are most noticeable. At least one size up. Important point: the shoulder seam should drop clearly for the oversized look to be perceived as a deliberate choice — anything in between gives the impression of an ill-fitting garment. Our hoodie guide details the available cuts.
T-shirts
Same size difference, but the stakes are lower: a slightly fitted t-shirt is still wearable, unlike a sweatshirt. This is also why a t-shirt is the best first order when discovering a store—it costs less and is more forgiving.
Sweaters and sets
For sets, check both pieces separately: tops and bottoms don't always size the same way. Our sweater guide details the correspondences.
Rings
A special case: here it's not a question of sizing standard but of finger circumference, a measurement no one knows by heart. Prioritize adjustable models, especially for gifts. Our jewelry guide specifies which models are adjustable.
🧥 Items where size matters
For these four, take one size up
Products without sizing issues
A large part of the catalog completely avoids the sizing question, which is useful to know when ordering for someone else.
Plush toys, keychains, pins and badges, figurines, puzzles, and all decorative items can be ordered with complete certainty. Socks are in a comfortable intermediate zone: they come in broad sizes that cover multiple shoe sizes.
However, two categories require precise information that only the recipient possesses: phone cases, where the exact model with its generation is needed, and rings.
🎯 No sizing risk
Safe bets when ordering for someone else
Ordering as a gift, without knowing the size
This is the most awkward situation: you want to give a surprise, so you can't ask. Three strategies work.
Ask someone else. A parent, roommate, or spouse knows the size and can provide it without giving away the surprise. This is the simplest solution and often overlooked.
Check a tag. If you have access to their wardrobe, a sweatshirt tag will solve the question in ten seconds—just remember to apply the one-size difference.
Bypass completely. This is often the best choice: opt for a product with no size. A figurine, a plush toy, or a set of badges avoids the problem and eliminates the risk of disappointment. Our adult gift and teen gift guides feature these products by profile.
🧠 Gifting Tip — If you're set on clothing despite the uncertainty, aim for larger rather than just right. An oversized sweatshirt will be worn; a too-small sweatshirt will end up in a closet — and the person won't dare to tell you.
If you made a mistake
A practical point to know before ordering: delivery times are 7 to 14 business days. An exchange is therefore not immediate, which makes upfront verification even more useful — especially for a dated gift, where you need to allow at least three weeks in advance.
For specific return or exchange procedures, refer to the conditions indicated on the store or contact customer service, who will handle the case directly.
Delivery is €5.90 in France and the European Union, free for purchases over €60, and €7 outside the European Union.
❓ Frequently asked questions
Do SpongeBob clothes run small?
Yes, for most models. Sizes follow Asian standards, which are approximately one full size smaller than French sizes. Order one size larger than your usual size.
What size should I take for an oversized look?
Two sizes above your French size. The shoulder should drop clearly: an in-between size gives the impression of ill-fitting clothing rather than a style choice.
How to measure without a tape measure?
Use a reference garment. Lay flat a sweatshirt that you find to be the right size, measure the width from armpit to armpit and multiply by two: this gives you the chest measurement to compare with the product sheet.
What if I hesitate between two sizes?
Always take the larger size. A garment that is too tight stretches the print and is immediately noticeable; a garment that is too loose can pass for a deliberate style choice.
Which products don't have sizing issues?
Plush toys, figurines, keychains, pins, puzzles, and decorative items can be ordered without uncertainty. Socks cover several shoe sizes. Only phone cases and rings require specific information.
How to order a garment as a surprise gift?
Ask a friend or family member for the person's size, or check a tag in their wardrobe. Otherwise, bypass the problem with a product that has no size — this is often the safest choice for a surprise.
Should I rely on the size chart or the product sheet measurements?
On the product sheet measurements, which always take precedence. The size conversion chart is a quick starting point; the centimeters indicated for the specific model are the reference in case of discrepancies.
What is the delivery time?
7 to 14 business days. Delivery costs €5.90 in France and the European Union, is free for purchases over €60, and €7 outside the European Union.
In summary: one size up by default, two for oversized, and the measurement of a reference garment to settle borderline cases. Three minutes of checking avoids two weeks of additional waiting. To choose the item itself, our style guide and the new arrivals page can help.
