What is DPI and Why It’s Essential in Print and Design

SW19 Design & Print, Wimbledon

At SW19 Design & Print, located in the heart of Wimbledon, we’re passionate about delivering top-quality prints. Whether you’re a local business owner, event planner, or designer, understanding DPI (dots per inch) is crucial for achieving stunning results. Here’s everything you need to know about DPI and why it’s important for your next print project in Wimbledon.

What Does DPI Stand For?

DPI stands for dots per inch, a key term used to measure the level of detail a printer can produce.

  • Higher DPI = Better Resolution: More dots per inch mean sharper, more detailed prints.
  • Knowing the right DPI for your project ensures a professional, polished result—whether it’s a flyer for your Wimbledon café or a large banner for an event at Wimbledon Park.


At SW19 Design & Print, we specialize in creating high-resolution prints that make your designs stand out.

What Exactly is DPI?

DPI measures the density of dots a printer can produce per square inch.

  • Low DPI = blurry, low-resolution images.
  • High DPI = crisp, professional-quality prints.


For businesses in Wimbledon, whether you need promotional posters or custom packaging, understanding DPI ensures your brand looks its best.

DPI vs. PPI: What’s the Difference?

It’s easy to confuse DPI (dots per inch) with PPI (pixels per inch), but they serve different purposes:

  • PPI: Refers to digital image resolution—how many pixels fit into an inch on a screen.
  • DPI: Refers to print resolution—how many dots of ink fit into an inch on a page.


If you’re preparing files for printing, our team in Wimbledon can help you navigate the technicalities to ensure your digital designs translate perfectly to print.

Can You Turn Low Resolution Into High Resolution?

If you have a low-resolution image, you can’t simply convert it to high resolution. However, techniques like upscaling can help improve the image quality.

At SW19 Design & Print in Wimbledon, we offer advice and tools to ensure your images are print-ready, even if they require adjustments like:

  • Dithering: Smoothing out pixels to reduce blockiness.
  • AI Upscaling: Using advanced technology to predict and enhance details.


Whether you’re printing wedding invitations or posters for a Wimbledon community event, we’ll ensure your prints look professional.

High DPI vs. Low DPI: What’s the Difference?

High DPI images (e.g., 300 DPI) are ideal for projects viewed up close, such as brochures or business cards. Low DPI images (e.g., 72 DPI) may work for large banners viewed from a distance, such as event signage for Wimbledon Common.

Table of Recommended DPI for Print Projects:

The Short Answer

  • If you're designing something that is going to be held in someone's hand (like a brochure or flyer) then the correct DPI is 300dpi. If you need to you can probably get away with 250dpi.
  • A poster needs a minimum resolution of about 100dpi if viewed at 6ft (2m).
  • Viewed at 30ft (10m) a billboard needs a minimum resolution of about 20dpi.
  • Printing a photo on your inkjet printer? Use 300dpi.

DPI: Better too high than too low

  • You can have a resolution that is too low, but you rarely have issues with an image where it's a little too high. So lean towards a higher resolution where possible.
