In th round to tight

how do I make the stitches looser when I knit in the round? I keep trying when I cast on the 100 stitches but each time it is to tight, I MEAN VERY HARD or either if they are loose the stitches get twisted and it is just a mess!! What should I do different?
Thank you ,Debbie

okay wait…is it too tight because you reeeeeeeeally have to stretch the stitches around? if so you need a shorter needle. Make sure you measure from tip to tip.

if it is too tight because the stitches are just too tight then maybe cast on over two needles and then just pull one out…or cast on to a bigger needle and just transfer the stitches.
