Ever designed a beautiful brochure or flyer, only to have it printed with essential elements missing from the edges?

It happens more often than you think. We have been running printing and signage agency for over 12 years and I still see designs without any bleed every day!

So, what's the standard bleed size for printing in mm?

The industry standard for bleed is 3mm on each side of your document.

This means your artwork (background only) needs to extend 3mm beyond the desired final size.

For example, if your finished flyer is 210mm x 148mm (A5 size), your document size in your design program should be 216mm x 154mm.

But how important is bleed, really?

It is very important!

Bleed refers to the extra area of your design that extends beyond the final trimmed size of your printed piece.

Without bleed, the print has a high chance of having white borders when it is cut to size.

Studies show that 72% of consumers form an initial impression of a business based on the quality of their printed materials.

Here's a quick table summarizing standard bleed sizes:

Why is understanding bleed crucial?

  • Avoid unwanted white borders: Get a visually seamless and professional outcome, contributing to that positive first impression (remember, 72% of consumers judge based on print quality).
  • Maintains image integrity: Prevents crucial elements like images or text from being cut off during trimming, preserving the visual message you intended to convey.
  • Enhances overall aesthetics: A clean, finished look with no white borders creates a polished and visually appealing final product.
  • Saves time: Prevents going back and forth with your printing company trying to get things right.

By incorporating bleed into your design workflow, you’ll guarantee your printed materials look their absolute best, leaving a lasting impression on your audience and potentially contributing to a positive perception of your brand.
