The 300x250 at a glance
| 300 x 250 | |
|---|---|
| Size | 300 x 250 px (ratio 6:5) |
| Google's name | Inline rectangle, widely called the medium rectangle |
| Where it shows | Inside articles and in sidebars, on mobile and desktop |
| File limit | 150 KB for uploaded image ads in Google Ads |
At 300 by 250 pixels there is room for a product, about five words and a button, and not much else. Everything below follows from that.
How to design a 300x250 that gets read
- One product, cut out cleanly and large enough to recognize. A wide lifestyle scene shrinks to noise at this size.
- A headline of five words or fewer, set big.
- A clear button shape with one verb: Shop, Try, Get.
- Your logo or name, small but readable, so people know where the click goes.
- A solid background or a thin border, so the ad does not melt into a white article page.
- Stay under 150 KB: flat colors and a compressed PNG or JPG help.
What StoreToAds makes instead
Fixed banner sizes and HTML5 banners are not offered yet. What every StoreToAds ad does include is the set of images Google's responsive display ads ask for: a 1.91:1 landscape at 1200 x 628 and a 1:1 square at 1080 x 1080, plus a 9:16 vertical. Google lists 300 x 250 among the most common display sizes, and responsive display ads adjust their size and layout to fill slots like it.
Two honest caveats. Our landscape image places the full ad design in the center of the 1200 x 628 canvas with its background carried to the sides, so it is the same ad, not a re-flowed banner. And Google's best-practice guide for responsive display ads prefers images without overlaid text, so add a few plain product photos from your store to the same ad.
If a publisher or ad network needs exact 300 x 250 files, StoreToAds is not the right tool today; a designer or a banner tool is. See how we compare with BannerBoo and Creatopy.
