As with many things in life, everyone is different. This also applies to normal urinary frequency. For most people, the normal number of times to urinate per day is between 6 – 7 in a 24 hour period. Between 4 and 10 times, a day can also be normal if that person is healthy and happy with the number of times they visit the toilet.
Normal urinary frequency also depends on how much fluid you drink in a day and the types of fluid that you drink. If you are taking medication for high blood pressure, for instance, it may increase because of the way some medication works; for example, medicines called "Diuretics". How healthy and active you are can have an influence, and to some extend your age e.g the normal frequency of urination in children can be different from that of an adult.
