A driver's weight is integral to the performance of a Formula 1 car and they are subject to strict diets and workout routines during the season.
Williams' F1 line-up of Albon and Sargeant is the tallest on the grid, with Albon the joint-tallest driver at 1.86 metres alongside Alpine's Esteban Ocon.
Sargeant is also among the tallest drivers in the field but is still several centimetres shorter than team-mate Albon.
Sargeant recently detailed that he has put on five kilograms in preparation for his second F1 season this year following a challenging rookie campaign.
However, Albon doesn't have the luxury to add extra weight due to his height.
“Unfortunately, Logan is about seven or eight centimetres shorter than me so he has the luxury to put on them four or five kilograms,” Albon told media including RacingNews365.
“If I did add four or five kilograms, I would be four or five kilograms overweight.
“My operating weight is already right on the limit. So it is a bit more difficult for me to put on muscle mass without making myself slower in the car.”

Albon targeting weight loss
Albon enters his third year at Williams as he continues to assist it with its recovery from a dip in performance, with the Grove-based squad attempting to leave behind being subject to operating at an uncompetitive level.
The Thai-British driver enjoyed a strong campaign last year and lifted Williams to seventh in the Constructors' Championship.
As he aims to go even better this year, Albon has set a target of decreasing his own weight as he likened a driver's fitness routine to that of a boxer.
“I had a very good winter training, I had for five weeks having a good shift but then right now actually I'm the opposite,” he said.
“I need to start to lean out. I need to start to lose a couple of kilograms before the season starts.
“The transition a little bit more towards the cardio and a little bit like a boxer.
“We kind of get the muscle in early and then once the season starts we need to get back to fighting weight.”
