If you can open your Instagram on a computer, go to your profile by clicking on your username located at the upper-right corner of the page. Once you’re on your profile page, just copy the link that’s on the browser’s address bar – that’s your profile URL.

If you can’t open your Instagram profile on a computer, don’t worry. You can also get your profile URL on your phone, or more like, figure it out.

Your Instagram URL is just Instagram’s website address plus your Instagram username, separated by slashes. So, if your know your Instagram username, then that’s it. Just insert it in this:
https://www.instagram.com/yourusername/

If you don’t know your username, open the Instagram app, click on your photo in the lower-right corner of the bottom menu bar, and it’ll take you to your profile. There, you’ll see your username at the top of the page.

Hope this helped.

Cheers.
