STEP 3. Profile pic & bio
The perfect picture for an instagram profile is a perfect square. For reference, keep in mind the minimum profile picture size for Instagram is 110 x 110 pixels
To add or change your profile picture: Go to your profile and click the "Edit Profile"
button - Then, tap "Edit"
in the top right. (This will appear under your current profile photo if you have one.)
Your bio is a space for you to tell users what your profile is about. Keep it simple, use hashtags and include a link to your website. Here are some examples
of good bios.
