"I recently reset my iPhone 5 running iOS 11 but when I try to restore it from a backup I had created earlier, I keep getting the error "iTunes could not restore the iPhone because not enough space is available on the device." This shouldn't make any sense since the iPhone has been reset, all data deleted. To try and fix the problem I did a backup and reset the device to factory settings. Now I can't even restore the device. Any help on how to get the device set up again?"

1Free up Your iPhone Space to Make Room for Restore
As obvious as it sounds, it may very well be that there isn't enough space on your device, hence the very poignant error message from iTunes. And before you argue with this statement, it may very well be that you are not aware of just how much free space there actually is on your device.
Therefore, it makes sense to see if iTunes is telling the truth or not. To do this go to Settings > General > Storage & iCloud Usage > Manage Storage and see just how much available space there is on your device. If you find that iTunes is in fact right, you might want to delete some unwanted apps and content to make enough space for the restore process to proceed successfully.
2 Make Sure Your iTunes or iOS is up to Date
If you clear up some iPhone storage space and you still get the same "iTunes could not restore" error message, it is likely that your iTunes is having some problems or that your the iOS version on your iPhone is not the latest. To fix this "iTunes could not restore because not enough free space" issue, you may try updating iTunes and iOS to the newest if they are not up to date, or just by reinstall both of them even if they are the newest.
To update iTunes, launch it on your computer and then click on "Help" and then choose "Check for Updates." If there is one available, allow it to update. You can also simply uninstall the version you have and then download the latest version from the Apple website. In some cases, it resolves the "not enough free space to restore" error quickly.
Another trick to troubleshoot this iTune restore error message issue, you may update iOS by plugging in the device to a power source and a Wi-Fi connection and then going to Settings > General > Software update. Tap "Install" if there is an update available and simply wait for the process to be completed.
