Thank you KenAccording to IG, the maximum width is 1080 pixels. They also say that they will compress anything over that amount. You are also limited in your aspect ratio between 1.91:1 to 4:5.
When I share a photo on Instagram, what's the image resolution? | Instagram Help Center
This person seems to believe that IG will apply compression to your images regardless of size: https://patkay.com/instagram-export-settings-lightroom/ . I do not use the service so I cannot confirm, but I would upload and then download an image or two t see if they do use compression if that is a concern to you.

I'm using the LRInstagram plugin for classic. In my opinion, this is the most simple and fastest way to publish from Lightroom to Instagram. Just drag photos to the publish collection, then click Publish to immediately upload your photos to Instagram.I am thinking two options
* Using LR Classic (my main platform) to select and crop for Instagram (as above)
You're one of the lucky ones -- it stopped working for most (but not all) a couple years ago after Instagram changed their undocumented protocol (and after Instagram-owner Facebook formally announced their discontinuance of desktop-app uploading).On their site is a warning that the plugin does not work currently but i don't have any problems with my version (v0.6.1582) on Lightroom Classic 10.2
