If you think of it in percentages it's like 75-80% the size of a 1/8 figure.
It's really more about the width but if you're at least the width of 2 of your fingers you're honestly fine.
Don't let randoms on the internet size shame you. The average length worldwide is like 13cm so you're above average.
