Outward appearance
Albus Dumbledore was tall and thin, with silver hair and beard (auburn in his youth) so long that they could be tucked into his belt. He had a very long and crooked nose that looked as if it had been broken at least twice. (It is speculated that his brother's punch during their sister's funeral may have played a role in shaping his nose.) He was also said to have long and skilful fingers. His eyes were described to be a brilliant, soul-piercing shade of blue, and usually twinkled with kindness and mischief.
Dumbledore wore half-moon spectacles and a colourful array of robes, ranging from purple to bright orange. He once claimed to have a scar above his left knee in the precise shape of a map of the London Underground, but whether or not he actually does is unknown. His demeanour is often – if not always – serene and ethereal, and he usually spoke in a calm, pleasant voice even when Harry thought that he was actually furious.
During the last year of his life, Dumbledore's right hand was scarred when he donned Marvolo Gaunt's Ring, which was cursed. Had Severus Snape not intervened with a counter-curse, Dumbledore would have died much more quickly. Regardless, the curse left his hand blackened and dead-looking, and no amount of healing could repair the appearance. According to Snape, the curse would eventually spread itself from the contained hand, and Dumbledore was doomed to die in no more than one year's time. Whether this means the blackening dead-look appearance would spread throughout the entire body is unknown.
