It might be related to the update of the Instagram app. Sometimes new updates can cause such display issues. Try reinstalling the app to see if that solves the problem.
It could be that you've added high-resolution images or long videos, which take up more space.
Maybe you added too many high-resolution images or videos. That could make the file size large.
It could be a glitch in the app. Sometimes, software updates or temporary bugs can cause such issues.
Well, sometimes it's due to the settings on your phone or the app. Check if your Instagram settings are set to capture or upload in large file formats. Another possibility is that you're sharing large files directly from your camera roll without optimizing them first.
Maybe it's because of the high-resolution images or videos you're using. Try lowering the quality to see if that helps.
There could be a few reasons. One possibility is that you're using a camera app with high-quality settings. Another is that the app itself might have some default settings that are causing the stories to be large. You could check both your device and the Instagram app settings to see if there's anything you can adjust.
It might be due to the high resolution of the images or videos you're uploading. Maybe you haven't adjusted the settings for size reduction.
It usually depends on the aspect ratio and the resolution of your device. But generally, it should be clearly visible and not too small or too large to look odd.
It could be that the settings on your device or the Instagram app itself are causing the story to appear larger. Check your app settings and device display settings to see if there's anything amiss.
I think it's because Instagram wants to provide a more immersive experience. The larger size allows for more details and better display of photos and videos.
