How much urine do you make, and how often should you go?
BMJ Group Medical Reference
How much urine your body makes depends on how much you eat and drink, and how much you sweat. Most people make 1.5 litres to 2 litres (2 pints to 3 pints) every 24 hours. 
You may have noticed that when it's hot you don't need to go as often and your urine is a darker yellow. This is because you're using more water to keep cool by sweating, so your body has less to make into urine.
How often you need to go to the toilet also depends on how much urine your body makes. Most people go four times to eight times a day. But this depends on other things too, such as how strong your bladder is and how you've 'trained' your bladder. If you're used to going every few hours out of habit, you'll go more often.
