Postcard Sizes for Print
Printing postcards is fairly easy. The challenge is identifying the right size before you click “Print.” So for you to be in the know, let’s discuss the various postcard sizes for print.
Small Postcards
Small postcards measure 4.13 × 5.83 inches. Any type of postcard can be printed as small postcards as long as the quality is good. And also, small postcards are less costly to print since they’re smaller.
Standard Postcards
Standard postcards are very cost-effective and typically measure 4 × 6 inches. They’re the most common postcards and they’re great choices for invitation postcards, thank you postcards, and personalized postcards.
Square Postcards
Square postcards are usually 4.72 × 4.72 inches. Their width and height measurements should match because if otherwise, they won’t be a perfect square. Square postcards can be used as wedding postcards and birthday postcards.
Medium Postcards
Medium postcards are slightly bigger than standard postcards measuring 5 × 7 inches. They can fit in photo frames of a proportional size if you want to frame them after printing. And because they’re bigger than standard postcards, you can fit in more freelance graphic design elements and larger pictures.
Half-Page Postcards
Half-page postcards measure 5.5 × 8.5 inches. They have plenty of room for additional designs and visual elements. So if your postcard has plenty of visuals, you should consider printing it as a half-page postcard.
Large Postcards
Large postcards usually measure 6 × 9 inches or 6 × 11 inches. They’re the best option for restaurant postcards, company postcards, and other postcards that advertise a product, service, or business.
Postcard Sizes for Email
The best size for images that’ll be inserted in emails is between 600 to 650 pixels. That applies to postcards as well since they’ll be attached to emails as image files. So before you insert your postcard into an email, make sure to adjust its digital size to at least 600 pixels and up. View a wider selection of basic postcard templates templates right here.
