Icon Prompts: Making Square Close-Up Avatars for Social Media

Social media icons are usually square and get cropped into a circle. With three tags, portrait (a close-up of the face), looking at viewer and simple background, you get an icon where the face is clear even when shown small.

The short answer

The basic prompt for a social media icon is portrait, looking at viewer and simple background. Make the image square from the start. Because it gets cropped into a circle, keep important things such as hair accessories near the center.

What is the prompt for an icon? (portrait, square)

The basics for an icon are portrait (or close-up) to show the face large, and looking at viewer. Make the image square (1024x1024, etc.). If you make it tall and crop it later, the top of the head or the shoulders get cut off, or the face becomes small.

What background prompt works for an icon?

Icons are shown small, so simple background or a single color such as "color + background" works best.

Because icons are shown small, a simple background makes the face stand out. For a single color use simple background, and to choose the color write "color + background", like pink background.

Background tags

Tag	Meaning	Note
`simple background`	Simple background	Close to a single color Details
`white background`	White background	Easy to cut out Details
`gradient background`	Gradient background	A little livelier than a single color Details
`pink background`	Pink background	Choose the color with "color + background"
`polka dot background`	Polka dot background	A cute pattern. Small dots read better
`blurry background`	Blurred background	Blur it when you want an outdoor scene Details

How do I make an icon? (steps)

Use a square size and add a face close-up, eye contact and a simple background. That is the basic flow.

Set the image size to square (1024x1024, etc.; the ratios you can choose depend on the service, so check)
Add portrait and looking at viewer, and choose one expression (smile, etc.)
Set the background to simple background or "color + background"
Write 1-2 features you want people to recognize, such as hair color, eye color or a hair accessory, a little stronger
When it is done, crop it into a circle, view it small, and check that the face is not cut off and the expression still reads

Combinations by mood

Mood	Combination	Notes
Bright and friendly	smile, looking at viewer, pink background	Pick this if unsure
Cool	expressionless, looking at viewer, gradient background	Pair with cool-colored backgrounds
Soft	head tilt, gentle smile, white background	Goes with pastel outfits
Energetic	open mouth, wink, peace sign, simple background	Keep the hand near the face. Remove it if it breaks
Seasonal	portrait, cherry blossoms, blurry background	Blur the background to add the season

What if the head gets cut off in a circular crop?

The main causes are framing too close, or making a tall image and cropping it afterwards.

Problem	Cause	Fix
The head gets cut off in a circle	Too close with close-up, or made tall	Use portrait or upper body and make it square. Add straight-on
The face is unreadable when small	Busy background or a small face	Use simple background and move the framing toward portrait
Hands cover the face and break	A hand gesture such as a peace sign was added	Remove the gesture. An icon works fine without hands
Looks like a different person every time	Too few defining features	Write the hair color, eye color and hair accessory the same way every time

Rinka's tips

An icon is mostly decided by four things: square, face close-up, looking at the viewer, simple background
A circular crop removes the four corners. Keep important things (hair accessories, etc.) near the center
Checking display sizes and crops for each social network with a size preview tool before posting is reassuring

FAQ

Frequently Asked Questions

What should I put in a prompt for an icon?

The basics are portrait (face close-up), looking at viewer and simple background. Make the image square.

The head gets cut off when I crop it into a circle.

Usually the framing is too close (close-up) or the image was made tall and cropped. Use portrait or upper body and make it square from the start.

What background works best?

Icons are shown small, so a single color or a gradient is best. If you want scenery, blur it with blurry background so the face stands out.

Can I use an AI-generated image as my icon?

It depends on the terms of the generator you use and of the social network. Commercial use and attribution differ by service, so check each official guide.
