Magazines do not all use one page size. Trim dimensions depend on the publisher, edition, printer and binding. One U.S. association publication's ad specifications list an 8.375 × 10.875-inch trim size; another publication may use different dimensions. For a real ad or cover, request the current publisher's print specifications before preparing the file.
Magazine Dimensions: U.S. Print Sizes, Ad Specs & Pixels
Magazine page size: why there is no one standard
A U.S. magazine size in inches, millimeters and pixels
A documented example trim size of 8.375 × 10.875 inches converts to about 212.73 × 276.23 mm. At 300 pixels per inch (PPI), that finished page requires 2,512.5 × 3,262.5 pixels, rounded to about 2,513 × 3,263 pixels.
| Example finished trim | Inches | Approx. millimeters | Pixels at 300 PPI |
|---|---|---|---|
| U.S. publication example | 8.375 × 10.875 in | 212.73 × 276.23 mm | 2,513 × 3,263 px |
The pixel count is a calculation for this example only, not a universal magazine preset.
Magazine cover aspect ratio and double-page spread
For the example trim above, width divided by height gives an aspect ratio of about 0.77:1 (or 1:1.30). Other magazine covers use other proportions because their trim sizes vary.
Two example pages side by side would have a nominal trim area about 16.75 × 10.875 inches before accounting for the gutter, binding, bleed, and printer-specific layout. A two-page advertisement must follow that publication's supplied spread template.
Magazine advertisement dimensions and bleed
“Full-page ad size” does not have one universal dimension. A publisher may specify the finished trim, a smaller live area, and a larger document size for bleed. For example, the Association Media Hub's print specs give one publication trim as 8.375 × 10.875 inches. Check its exact ad template and safe area before submission; never assume another magazine accepts the same file dimensions.
Frequently asked questions
What size is a magazine page?
There is no single size for every magazine. One documented U.S. publication example uses an 8.375 × 10.875-inch trim; confirm the exact title and edition.
How many pixels is a magazine cover?
It depends on the physical trim and required print resolution. For an 8.375 × 10.875-inch example at 300 PPI, the trim is about 2,513 × 3,263 pixels.
What are Sports Illustrated's dimensions?
Use the print specifications for the particular edition or issue. This page's example trim is not a verified Sports Illustrated specification.
Is A4 a magazine size?
A4 is a paper format measuring 210 × 297 mm. A magazine may choose A4 or another trim size; the publisher determines the finished page and bleed.
