If you’ve ever shopped at Zara, you know their sizing can be… unpredictable. One pair of trousers fits like a glove, while the next feels two sizes off. But here’s a little insider secret that can make your shopping experience so much easier: Zara actually gives you a hint about how each item fits—right on the tag.

Look for the Shape on the Care Tag

Flip over the care label (usually found inside the garment) and you’ll notice a small shape symbol printed near the size information. This shape is the key to understanding how the item fits:

Square means it’s True to size
If you see a square, it means the item is designed to fit as expected. Go with your usual size.

Triangle means it Runs small
A triangle indicates the item runs smaller than standard sizing. Consider trying one size up for the best fit.

Circle means it Runs large
A circle means the piece runs bigger. Sizing down might give you a more tailored fit.

Why This Hack Works: Zara uses this discreet system to help shoppers navigate its often inconsistent sizing. Instead of trying on three different sizes “just in case,” you can use the symbol as a guide to zero in on the best starting point.

Pro Tip: This trick works both in-store and online—if you zoom in on the product photos or check the product details, the shape is often shown there too.
