Flame size setting

I am Japanese and I am using the translation function, so please understand that there may be some parts that are not correct. When I am in the nether in a survival situation, I often get flames on my body and when I try to move, the flames get in the way and interfere with my play. So I think it would be better if you could make the flame smaller or bigger by 0~100% in the settings so I can play more comfortably. Please do so.
