Create Facebook Posts with AI

By Melon Cut ·

Facebook is different from other networks. People read longer text, share events with friends, and click links. When you create Facebook posts with AI, the picture has to do a different job than it does on a purely visual feed. This article explains which formats to use, what kinds of posts work, and how to prompt for each.

Pick the right picture shape

Facebook shows several shapes well, so match the format to the purpose.

  • Portrait 4:5 (1080 x 1350): good for a single strong picture in the feed.
  • Square 1:1 (1080 x 1080): safe everywhere, easy to reuse on other networks.
  • Landscape link image (1200 x 628): the shape used when you share a link. Use it when the post points to a page, a booking form or an article.
  • Story 9:16 (1080 x 1920): for Facebook Stories.

For link posts, see the Facebook Link Image Size Guide. Our size guide lists all formats side by side.

Four kinds of Facebook post worth making

Announcements

A new opening time, a new service, a new location. Keep the picture calm and the headline plain.

A landscape link image, 1200 x 628, of a bright shopfront with its door open, morning light. Text on the left: "Now open on Sundays". Clean space on the right.

Events

Facebook events live or die on a clear date. Put it in the picture, in large type, and read it twice before you post.

A portrait Facebook post for a neighbourhood book fair. A table of colourful books under string lights, evening mood. Text at the top: "Book Fair". Text at the bottom: "Saturday, 10 to 4, Town Hall". Leave the middle clear.

Offers

Say what the offer is and when it ends. Do not rely on the picture alone; the caption should repeat the terms. Always check the picture's text for the correct item and date, because AI can misspell or alter words.

Community and behind the scenes

Facebook audiences often follow a place because they know the people. Show the workshop, the kitchen, the team at work. A picture that looks real and warm usually works better than a polished advert.

Write the picture for the feed, not for yourself

Facebook posts are seen small and often in a hurry. Use few words, large type and strong contrast. Keep important content away from the edges, since the social formats in Melon Cut keep safe areas of 13% on each side and 12% top and bottom for posts.

Keep branding steady

Facebook pages are often where people check you are real. Naming your brand with @ in the prompt makes sure the logo, colours, fonts and voice follow your guidelines, so a post from March looks like it came from the same business as a post from November.

Captions

Facebook can carry a longer caption than most networks. Ask for a draft, then edit it so it sounds like you and includes the exact details: address, hours, link. If you need ideas for what to say, What to Post on Social Media When You Run a Small Business has a simple mix.
