A picture is worth a thousand words, even in a text message. So incorporating images, GIFs and videos into your mobile marketing strategy can increase open rates and engagement. For example, interactive MMS and SMS campaigns generate conversions 70 percent of the time, while passive content converts only 36 percent of subscribers.
MMS (short for multimedia messaging service) text messages are often more successful than plain text SMS messages. In this guide to MMS image size, we’ll share how to optimize media in your MMS marketing campaigns to ensure your marketing messages are deliverable and easy to view.
Why MMS Image Size and Orientation Matters
While some consumers cannot receive MMS texts, the vast majority of people have MMS-capable mobile phones, although screen dimensions do vary. Therefore, keeping MMS image size in mind while building your campaign can help you create a sleek, professional MMS campaign for your subscriber list.
As smartphone screens get larger each year, MMS image size and orientation are crucial in developing a successful MMS marketing campaign. Over 96 percent of consumer mobile device screens are in portrait mode (tall), so most MMS marketing graphics are designed with that in mind.
Sometimes image previews can be covered unless the image is tapped. Before sending a text message with an informative graphic about an upcoming sale or special discount, use portrait orientation to ensure that your image isn’t cut off.
Because these images are only ever on a smartphone screen, MMS image size is usually relatively small. If an image’s file size is too big, it might not load for your recipient or even send at all.
Size and Format Recommendations for MMS
The optimal format for MMS images is a JPEG file that does not exceed 500 kB. We suggest designing your MMS graphics with the file type, size and dimensions in mind, rather than resizing existing graphics into smaller images for your MMS campaigns. While you can compress images to lower the file size, sometimes this process can reduce the image quality.
Suggested Image Size
The optimal aspect ratio for MMS images is 9:16, which works best across smartphones of different sizes and manufacturers. This comes out to 1,920 x 1,080 px, or 1,138 x 640 px.
Suggested GIF Size
GIFs are the best way to send animated images, although these need to be much smaller than a static image.
- For square GIFs, we suggest 480 x 480 px or 640 x 640 px.
- For a portrait mode GIF, we suggest 480 x 640 px or 480 x 720 px at most.
Suggested Video Size
We recommend that MMS videos remain under 20 seconds to ensure that as many phones as possible receive and display the video correctly. For the dimensions of your MMS videos, we suggest vertical videos at 640 x 1,138 px (9:16 aspect ratio).
If you can, try to use 30 frames per second and limit your file size to no larger than 1MB. Unfortunately, while you can technically send large video files, not all mobile carrier networks will receive them. For example, while Verizon receives videos up to 1.5MB, AT&T and T-Mobile will only accept files that are 1MB or less.
Suggested Text Length
The standard SMS text message is 160 characters; therefore, many SMS subscribers expect brands to keep their marketing messages short and sweet. Textedly allows users to include up to 1,600 characters alongside MMS messages. However, when pairing with media, we recommend sticking to shorter copy to maintain interest from your audience better.
How to Reduce the Size of a Picture for MMS
While you might be tempted to reuse existing graphics for your MMS campaigns, file size and image quality are significant factors for MMS messaging. With a standard max file size of 500 kB, many brands create graphics specifically for their MMS marketing campaigns to ensure delivery and high-quality images.
Maintain a Fixed Aspect Ratio
The aspect ratio of an image is the ratio of its width to its height. When an image’s aspect ratio is not fixed, you could accidentally stretch or skew the image in your photo editing software. Maintaining a fixed aspect ratio is just a matter of checking a box in your photo editor, which usually comes with standard aspect ratios like 9:16.
Reduce Image Quality
To keep your image under the 500 kB maximum file size, try to avoid using gradients or overly complex designs. A simpler graphic results in smaller file size, meaning that if you need to compress the image, the quality won’t suffer too much. You can reduce your image quality quite a bit before it starts to look pixelated.
