The Prophet ﷺ was of moderate height having broad shoulders (long) hair reaching his ear-lobes. Once I saw him in a red cloak and I had never seen a more handsome than him."  

كَانَ النَّبِيُّ ﷺ مَرْبُوعًا بَعِيدَ مَا بَيْنَ الْمَنْكِبَيْنِ لَهُ شَعَرٌ يَبْلُغُ شَحْمَةَ أُذُنِهِ رَأَيْتُهُ فِي حُلَّةٍ حَمْرَاءَ لَمْ أَرَ شَيْئًا قَطُّ أَحْسَنَ مِنْهُ قَالَ يُوسُفُ بْنُ أَبِي إِسْحَاقَ عَنْ أَبِيهِ إِلَى مَنْكِبَيْهِ  

Messenger of Allah ﷺ was the handsomest of all the people, and had the best appearance. He was neither very tall nor short.  

سَمِعْتُ الْبَرَاءَ يَقُولُ كَانَ رَسُولُ اللَّهِ ﷺ أَحْسَنَ النَّاسِ وَجْهًا وَأَحْسَنَهُ خَلْقًا لَيْسَ بِالطَّوِيلِ الْبَائِنِ وَلاَ بِالْقَصِيرِ
