1. 24″ x 36″ – Best for large window promos

This size is excellent for making a clear, bold statement people can spot easily while walking or driving by. If you’ve got a big front window and a big promotion, this is what you should be using.

Common examples of large window displays:

• “SALE NOW ON”
• “OPENING SOON”
• “LIMITED TIME OFFER”

Use clean, large fonts and stick to just one message. Don’t treat it like a flyer. When creating your copy, imagine you’re making a billboard, but on glass.

Design tip: Don’t display too much information. Stick to one offer or a single call to action.

2. 16″ x 20″ – Ideal for entry doors and general info

Walk into any retail store, salon, or cafe and there’s a good chance you’ll see something in this size range displayed on a glass door. It is often used to announce business hours, safety guidelines, or short promos.

The size feels substantial without overwhelming the storefront. If you don’t know what size to get, start with this one.

Best paired with:

• High-contrast design
• Minimal text
• Seasonal or temporary messages that need to be replaced often

3. 8″ x 8″ – Great for product highlights and supporting messages

These clings are effective when they’re placed close to eye level on glass counters or side windows. They usually don’t carry the main message — but they’re often used to display seasonal products, temporary promos, and add-ons.

Common examples of 3.8” x 8” window clings’ uses:

• “NEW!” labels on windows near products
• “Limited Time Only” promos
• Highlighting a new arrival or featured service

Helpful tip: Use multiple clings in this size to guide the eye or reinforce a promo. Just one may go unnoticed, but three in a row? That will most likely work.

4. 5″ x 5″ – Good for logos, labels, and quick reminders

When designing this window cling size, imagine you’re giving a “quiet” reminder to people rather than “shouting” to get their attention. This size works for subtle, supportive content — like branding, instructions, simple reminders, Wi-Fi info, social handles, and small logos.

Common uses of this size:

• Near door handles (“Push” or “Use Other Door”)
• Bathroom mirrors with branding (“Tag us @____”)
• On glass cases or shelves

Design tip: Use icons or graphics rather than long text.

5. 4″ x 4″ – Best for QR codes and scan-to-pay signs

This size is all about close-range readability and interaction. This is the “tap,” “scan,” or “follow” display that’s often used for contactless menus, downloads, or reviews.

Perfect for:

• Restaurant tables
• Checkout counters
• Car window messages (e.g. “Scan to Book”)

Make sure your QR code has room to breathe. No busy backgrounds, no tiny details. Just the code, a short label, and maybe a logo.
