Best Postcard Sizes for Direct Mail
There are plenty of postcard sizes for direct mail, however there are 3 common sizes that we feel are the best to choose from. There are pros and cons to all, and depending on your project goals, we will help you choose the best fit.
4 x 6 Postcards
A 4 x 6 direct mail postcard is the most common size. It is most likely what you imagine when you think “standard” postcard. This size will qualify for standard presort bulk postage rates, as well as a discounted presorted first class rate. Due to the smaller size, Seattle Mailing suggests using this size if you have a single message. You don’t want to over crowd with this postcard size.
Pros
- Smaller size = more affordable
- Qualifies for discounted first class rates
- Great for quick messages like save the date
Cons
- Common size
- May not stand out
- Harder to fit content
5.5 x 8.5 Postcards
Next is a 5.5 x 8.5 direct mail postcard. In the middle of our three best postcard sizes for direct mail, this size combines affordability and real estate to design with. This size will qualify for standard presort bulk rates, however will not qualify for the same discounted first class rates as the 4 x 6. If you are new to direct mail postcards, we suggest starting with this size.
Pros
- Slightly larger and still affordable
- Taller than an envelope
- Easier to fit more content
Cons
- Doesn’t qualify for discounted first class rates
- Somewhat common size

6 x 11 Postcards
Last we have the 6 x 11 direct mail postcard size. This is the largest of the three sizes we suggest, and is about as large as you can go and still pay standard bulk postage rates. If your postcard is larger than this, your postage will bump up into the “flat” category. Slightly more expensive to print, but great space to include multiple messages or coupons.
Pros
- Large space for more content
- Not a common size
- Stands out
Cons
- Cost more to print
- Doesn’t qualify for discounted first class rates
