How to Create Better Social Media Graphics With AI Images

Social posts have to cut through on the small screen. A great image is of no use if the subject is minuscule, the message is difficult to read, or key details get cut off. You need to start with layout and clear communication rather than just the visual.

Choose One Message Per Graphic

Decide on your objective before you start. Your post could be to announce a store opening, share a tip, promote a new product, or send people off to read an article. If you try and fit in every benefit and every detail in one image, it just tends to look a bit cluttered.

For instance, if you’re promoting a beginner class at a gym, you’d want to use a friendly image and leave space for the class name. The schedule, price, and how to book would all go in the caption or on a separate slide.

Plan the Canvas and Safe Areas

Square images are generally the best for feed posts, vertical for stories and video covers. Always check the most up-to-date image specs for each platform prior to export, as the sizes and cropping can change.

Keep your key faces, products, and headlines well away from the edge. Some apps will have the profile name, the button, or the caption sitting right over your image. It’s safer to leave a margin than to have anything right up against the edge.

Generate the Background Before the Text

When using an image tool, get a clear focal point and some space for your text. An example prompt might be: ‘Create a vertical photo of a runner tying their shoes on an outdoor track at sunrise. Keep the top third of the image simple and uncluttered for a headline. Warm natural light, realistic proportions, and no text in the image.’

Adding your headline in a graphics editor gives you full control over the spelling, the fonts, and how the text pops. If you’re generating the text within the image, then you’ll need to check every word very carefully.

Maintain a Recognizable Visual Style

Consistency doesn’t mean every post has to be the same. Just pick a few rules really (two or three colors, one lighting style, a particular crop, a certain way of dealing with fonts, etc.). Save a sample image or some prompt notes for future reference.

For instance, a café might go for warm daylight, cream backgrounds, and close-ups of the food. A software company might opt for a clean interface style with a more ‘cool’ color palette. Just make a note of your choices so that someone else can go and produce the appropriate graphics at a later stage.

Compare Image Versions Fairly

When you’re testing with a generator, only change one major thing at a time. Try a close-up crop against a wide shot, or a plain background against a real location. Keep the text, the offer, and the audience exactly the same so you can see which image performs best.

If you are evaluating a service linked under Nano Banana 2.1, check its actual model name and available controls before committing to a campaign. Treat that label as something to verify rather than evidence of particular features. Test whether the output leaves enough space for your headline and survives the intended crop.

Add Accessibility and Quality Checks

Make sure your text clearly stands out against the background. Use readable fonts and don’t just put the key information in a complicated image. Write alt text that describes the content of the image (not just the caption).

Look at your finished graphic on a phone. A headline that looks large enough on your laptop may well be too small on a phone. Check that all the faces, hands, labels, and logos are correct from the image generator.

Create a Repeatable Publishing Checklist

Use a short checklist for each graphic: clear purpose, correct size for the channel, accurate headline, brand colors, believable image details, rights checked, and a visible call to action.

Before you go any further and start scheduling your campaign, make one full sample post (with image, headline, caption and link). Have a colleague have a quick look at it on their phone and tell you what the message is. If they can’t see the offer or next step, then tweak the layout accordingly before you make any more posts.

Save your approved template with the image and text on separate layers. That way you can reuse the same fonts and spacing for future graphics; replace the image and the text. Saves time and still gives you a unique post each time.

Keep the final exported image with the prompt and source files. If you need to amend a scheduled post (e.g., change the date or the offer), edit the text layer and check the export rather than going through the whole process of creating a new image.
