A full-size default picture is a great way to make your profile look more professional on Instagram. When people visit your profile, they'll be able to see your picture right away, rather than having to click on a small thumbnail.

To set a full-size default picture, go to your profile and tap the three lines in the top left corner.

Tap "Settings," then "Profile." Scroll down to "Picture" and tap "Change." You can either choose a picture from your camera roll or take a new picture.

If you choose a new picture, make sure it's in landscape orientation and at least 1080 pixels wide.

If you have a profile photo that's already in landscape orientation, it will automatically be set as your full-size default picture.

You can also choose to have a different picture as your profile photo and your full-size default picture.

Just tap "Change" under "Profile Photo" and select the picture you want to use.
