Adjusting Tension in Knitting

Is there any technique or tip as to how to adjust the tension in knitting, correctly? Don’t know why there are always many knit sts that look bigger than others in my work, and my purl sts in general look tight. Very frustrating.:shrug:

Just practice. The more you knit, the more even your tension gets. And washing or blocking when you’re finished helps even the sts out a lot.
