Do I just 2x the size of the file while maintaining it's ratio? Like lets say I want to upload a high res image to instagram? What do I have to do to maintain a very high res image?

Social media sites use their own rules how they mangle photos. They need to try to keep the storage costs low enough to maximize their profits.
You must be somehow important to the media company (for. ex. the biggest owner) to force them behave as you want. Social media companies do not care of ordinary punters, they are only the food - the special one which imagines he is eating.
But you can optimize your images so that their automation causes the least amount of damage (=have certain pixel dimensions, but do exceed them, have certain aspect ratio, have more contrast than needed at your own PC, do not compress it to low quality before uploading) Search for guides.

It'd be good to include the relevant parts of the links inside of your answer instead of just linking to them in case the third party sites go down. Commented May 6, 2021 at 18:17

1The essentials are in the answer. The companies probably change the critical numbers often when they see some storage maximization strategy has become too widely used.– user82991Commented May 6, 2021 at 18:24

The customers of the Facebook (not you nor other users, but those who pay to Facebook for collecting data and showing "the right" content) probably have not shown enough willingness to pay for getting to know what fonts different pieces of the food prefer.– user82991Commented May 6, 2021 at 21:42
