Best Size for Service Due Stickers (What Workshops Should Actually Use)

by kyle Sevenoaks April 19, 2026

Choosing the right service due sticker size seems simple… until you start using them daily.

Too small — hard to read, customers ignore it. Too big — looks messy, doesn't fit properly on the windscreen.

So what's the right size? This guide breaks down what sizes workshops actually use, when to use each one, and how to choose the best option for your business.

🔍 Why Size Matters More Than You Think

Sticker size directly affects readability, placement, professional appearance, and customer engagement.

👉 If the customer can't quickly read it, it won't work

📏 Most Common Service Sticker Sizes (Australia)

🟢 Small (40mm – 50mm range)

Best for: Minimal setups, tight windscreen space, subtle placement.

Pros: Doesn't take up much space, easy to place anywhere.
Cons: Harder to read, limited writing space.

👉 Good for low-volume or basic use

🟡 Medium (60mm – 70mm range)

Best for: Most workshops, everyday servicing, balanced visibility.

Pros: Easy to read, enough space for writing, clean look on windscreen.
Cons: None significant.

👉 This is the most commonly used size

🔵 Large (80mm – 100mm+)

Best for: Fleet vehicles, trucks and machinery, high-visibility needs.

Pros: Very easy to read, more space for notes, strong presence.
Cons: Can look oversized in smaller vehicles, needs careful placement.

🧠 What Workshops Actually Prefer

From real-world use, most workshops settle on the 60mm – 70mm range. Big enough to read, small enough to fit cleanly, works across most vehicles.

🚗 Matching Sticker Size to Vehicle Type

Standard cars: Medium size (60–70mm)
4WDs / utes: Medium to large (70–90mm)
Trucks / machinery: Large (80mm+)

👉 One size doesn't fit all — but medium works in most cases

📍 How Size Affects Placement

Larger stickers need more space and must be positioned carefully. Smaller stickers offer more flexible placement and are easier to apply quickly.

👉 Always aim for the top corner of the windscreen — driver side preferred

⚠️ Common Mistakes to Avoid

❌ Using stickers too small to read
❌ Choosing size based on cost only
❌ Inconsistent sizes across jobs
❌ Oversized stickers in small cars

👉 These reduce effectiveness and look unprofessional

💡 Pro Tip: Standardise Your Size

The best workshops use ONE main size consistently. Faster workflow, cleaner look, stronger brand consistency.

Pair with custom branded stickers for maximum impact — same size, same position, every vehicle.

🔄 What About Double-Sided Stickers?

Size matters even more here — you need enough space for internal writing and clear external branding. Medium to large sizes work best.

📦 Should You Stock Multiple Sizes?

General workshop: Stick to one size (60–70mm)
Mixed vehicles / fleet: Keep two sizes — medium and large

🚀 Final Thoughts

The right sticker size makes a big difference. Best overall choice: 60mm – 70mm range. It gives you readability, clean placement, and a professional look.

🔥 Time to Standardise?

If your current stickers are too small to read, too big to place properly, or inconsistent across jobs — it's time to upgrade.
