About
What is Print Quality and Why Does DPI Matter?
DPI stands for Dots Per Inch. It measures how many pixels of your image fit in one inch of the printed output. The higher the DPI, the sharper and more detailed your print will be.
For flex banner printing the standard is 72 DPI at actual print size. This is because flex banners are viewed from a distance of 5 to 10 feet or more. Small banners viewed up close need 100 to 200 DPI. Large hoardings can work with 30 to 50 DPI.
Before sending your design file to the printer always check image resolution at actual print size. A high resolution image that looks perfect on screen may print blurry if DPI is too low at the required banner dimensions.
DPI Standards
DPI Requirements for Different Print Types
| Print Type | Minimum DPI | Recommended DPI | Quality |
|---|---|---|---|
| Large Hoarding | 30–50 DPI | 72 DPI | Standard |
| Flex Banner | 72 DPI | 100–150 DPI | Good |
| Poster / Standee | 150 DPI | 200–300 DPI | High |
| Visiting Card | 300 DPI | 300–600 DPI | Ultra |
Always check with your printer for their specific DPI requirements before finalizing the design file.
