A Large Head in a Small Frame
At least 30mm of head inside a 40mm photo.
Colombia's guidance sets a minimum head height of 30mm within the 40mm-tall frame — around 75% — with a minimum of 2.5mm between the top of the head and the top edge.
That is a tight crop. A photo taken from across a room, then cropped in, will not have the resolution to hold up. Have someone photograph you from about a metre and a half away instead.
