The Urantia Book is not specific about Jesus looks. However, it does give the following general account of him:

Although Jesus was poor, his social standing in Nazareth was in no way impaired. He was one of the foremost young men of the city and very highly regarded by most of the young women. Since Jesus was such a splendid specimen of robust and intellectual manhood… (127:5.1)

The Master displayed great wisdom and manifested perfect fairness in all of his dealings with his apostles and with all of his disciples. Jesus was truly a master of men; he exercised great influence over his fellow men because of the combined charm and force of his personality. There was a subtle commanding influence in his rugged, nomadic, and homeless life. There was intellectual attractiveness and spiritual drawing power in his authoritative manner of teaching, in his lucid logic, his strength of reasoning, his sagacious insight, his alertness of mind, his matchless poise, and his sublime tolerance. He was simple, manly, honest, and fearless. With all of this physical and intellectual influence manifest in the Master’s presence, there were also all those spiritual charms of being which have become associated with his personality–patience, tenderness, meekness, gentleness, and humility. (141:3.1)

Thanks for this question about Jesus. There is a great deal of interest in discerning what he looked like, but perhaps it is best that we really don’t know. This way, peoples of all races and ethnic groups can more closely identify with him; but in the end, it is Jesus’ Divinity and his legacy that has changed this world so dramatically.
