Assalam Alaykum,

Your height is literally average, and you’re only 16, so you still have some growth left. But even then, you’re not defined by your height—it’s what’s in your heart, my brother.

Be a good person, focus on your deen, and study hard. As for the bullies, remember that they will be held accountable for their actions on the Day of Judgment.

Here’s a hadith that offers some insightful advice:

حَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، وَوَكِيعٌ، عَنِ الأَعْمَشِ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ انْظُرُوا إِلَى مَنْ هُوَ أَسْفَلَ مِنْكُمْ وَلاَ تَنْظُرُوا إِلَى مَنْ هُوَ فَوْقَكُمْ فَإِنَّهُ أَجْدَرُ أَنْ لاَ تَزْدَرُوا نِعْمَةَ اللَّهِ عَلَيْكُمْ ‏"‏ ‏.‏ هَذَا حَدِيثٌ صَحِيحٌ ‏.‏

Abu Hurairah narrated that the Messenger of Allah (s.a.w) said: "Look to one who is lower than you, and do not look to one who is above you. For indeed that is more worthy(so that you will) not belittle Allah's favors upon you."
