The pixel width of email blasts

My colleague Kathy asked me what the design width of email blasts should be. I had to admit I had no idea. So I did a little research in my inbox, measured my recent html email blasts and notifications and here are the results. Pixel width is approximate, I might be off a pixel or two. All widths are in pixels.

  • Starbucks: 736
  • Newegg: 652
  • Amazon: 663
  • Gap: 703
  • B&N: 665
  • LinkedIn: 590
  • PayPal: 600
  • Apple: 600
  • Peachpit: 636
  • Netflix: 541
  • Twitter: 712
  • At&T: 592
  • UPS: 588

There you go, Kathy. Email designs are between 541px and 736 with an average width of 637 pixels.
