Confused and frustrated

I have been stuck at the same weight for a year now, plus or minus 5 pounds. I’m 227. Which is frustrating but not why I’m posting. I’ve just took my measurements for the first time since July and I’ve gone up an inch/inch and a half in my measurements even though I’m the same weight. I’ve recently started working out more often and tracking my calories with a food scale. Anyone know why I’m gaining inches? My clothes are fitting better and looser. It is so discouraging though to see the numbers go back up. Google isn’t much help so thought I’d come here and see if anyone else has any experience with it.
