At East London Printer, we help people all over London choose the best paper size for their projects. Whether youre a business, student, or designer, this guide will help you understand paper sizes and what to use them for.

What Are Standard Paper Sizes?

Most paper sizes in the UK and Europe follow the ISO 216 standard. The most common sizes are from the A-series, but there are also B-series and C-series papers.

A-Series (Most Used):

• A0 to A10 (Each size is half the one before it)
  
  

• A0 is the biggest, and A10 is the smallest
  
  

• Common sizes include A4, A5, and A3
  
  

Heres a quick look:

What About B-Series and C-Series?

The B-series is slightly larger than the A-series. Its used for things like posters and books. The C-series is mostly used for envelopes. For example, an A4 sheet fits into a C4 envelope.

Industry Tips for Better Printing

Here are some useful tips when working with paper sizes:

1. Leave room for margins and bleed: If your design goes to the edge, add a 3mm bleed area.
   
   

2. Think about layout: Some designs look better with more space. Dont squeeze text.
   
   

3. Fit for purpose: A big poster is no good if your audience cant carry it. Choose a size that matches your goal.
   
   

4. Use quality paper: The size is just one partpaper quality also affects the feel and look.

Paper Size & Creative Design

Designers often start with the end use in mind. For example:

• A6 is great for vouchers or mini invites.
  
  

• A5 can be used for folded cards or flyers.
  
  

• A3 gives more visual impact for artwork or promotional pieces.
