Logo Requirements for Sponsors: Size, Format, and Quality Standards

Nothing looks worse than a pixelated sponsor logo on your event website or a stretched logo in your printed program. Yet many organizers receive unusable logo files from sponsors, leading to last-minute scrambles and frustrated designers.

The Problem with "Just Send Us Your Logo"

When you ask sponsors for "their logo" without specifications, you might get:

Low-resolution JPEGs (200x200px) that look blurry when enlarged
Logos with backgrounds that clash with your design
Wrong file formats (Word documents, screenshots)
Multiple versions with no guidance on which to use

Standard Logo Requirements

File Formats

Required:

PNG with transparent background (for digital use, overlays)
Vector format (SVG, AI, or EPS - for print, scalability)

Optional but useful:

High-res JPG (for specific print applications)
White version (for dark backgrounds)

Minimum Resolution

Digital use: 500x500px minimum (1000x1000px preferred) Print use: 300 DPI at intended size

Rule of thumb: If the logo will appear 3 inches wide in print, you need a file that's at least 900 pixels wide at 300 DPI.

File Size

Maximum: 5-10 MB (larger files are usually unnecessary)
Typical: 50-500 KB for PNG, 100-200 KB for SVG
