The key thing to bear in mind about meta descriptions is that you’ve only got a certain amount of space to work with. How much space is arguably up for debate; most people put the upper limit of meta descriptions on Google at 156 characters, but it’s not exact, and the length of meta description displayed also depends on the device, with meta descriptions naturally being shorter on mobile.
