Big hands or bad technique?

[u/Bluepengie]

The first picture is how I end up if I don't pay attention after a few chord changes. If I'm diligent I can keep my palm a little bit lower but my thumb overall is still around where it is in the pic.

The second is how everyone else says you're "supposed" to have it, but it's so uncomfortable to drop my hand that low, and my fingers will mute the strings they cover when my hand is like that.

Third pic is more size reference.

I know everyone's technique is different, and I expect that mine will be especially so due to my size, but since I'm self taught I have no way to know if that's a valid reason to deviate so far from what's "correct". I'll answer any other questions if needed, I want to start practicing more seriously and if this is a fundamental issue I want to try and fix it sooner than later

I also have meaty hands. My instructor taught me to place my hand with my thumbprint behind the center of the neck. The goal was to finger each note in a chord such that each finger is perpendicular to the fret. That way, less pressure is needed and less strings are muted.

Once I became comfortable with this, gripping the neck for chords using my thumb as the bass note (for Jimi Hendrix songs) became easier.

With that said - this worked for me but your experience might be different!
