Paper Size Comparison Made Simple

If you’ve ever ordered printing services and got confused by paper sizes like A4, A5, or B5, don’t worry... You’re not alone! At Percetakan Aqrab Maju, we deal with paper sizes every day. Here’s a quick and easy guide to help you understand which size is right for your project.

Various sizes of paper are organized to showcase different creative possibilities.

📐 Quick Paper Size Chart

Size	Dimensions (mm)	Common Use
A3	297 x 420 mm	Posters, menus, folded brochures
A4	210 x 297 mm	Standard documents, letters
A5	148 x 210 mm	Flyers, notebooks, small brochures
B5	176 x 250 mm	Books, planners, premium notebooks
A6	105 x 148 mm	Postcards, thank you cards

📸 Visual Size Comparison

Imagine this:

📄 A4 = Standard printer paper (what you use every day)

📄 A5 = Half of A4 (fold an A4 paper in half)

📄 A3 = Double A4 (like 2 A4s side by side)

📄 B5 = Slightly larger than A5, used for high-end booklets or planners

📦 What Size Should You Use?

Use A3 if you need to catch attention — perfect for posters or event menus.

Use A4 for official documents or forms — the most standard format.

Use A5 if you want to distribute flyers or print compact brochures.

Use B5 if you're going for a more premium, book-style look.

💡 Bonus Tip: Orientation Matters

Portrait = Great for reading and lists.
Landscape = Best for charts, menus, or images.
