oh boy...first of all sukuna is taller and toji is borderline malnourished. its part of why he feels so "weak" and it frustrates him bc he knows hes physically strong but hes never at full energy. ever since their sukunas growth spurt he overpowers toji pretty easily. id say he has about 5cm on toji, and he's broader. sukuna loves touching toji any way he can so i like to imagine his big hand on the nape of tojis neck or around tojis tiny wrist 🫠🫠
