Urge first?

Did you feel an urge to pee just before the leak?
Leaked on the way to the toilet? Write 4 in the urge column for that trip, with no separate leak row. Leaked at another moment (a cough, a sneeze, lifting)? Give it its own row: the time, then the leak columns.

How to fill it in
Measuring what comes out
You need a container you can read a number off. A kitchen measuring jug works, so does a plastic measuring cup from a pharmacy, or any container you have filled once with a measured amount of water and marked with a pen. Place the container in the toilet bowl, pass urine into it, read the volume in millilitres, and write it in the second column. If you miss one, leave the amount blank but still record that a trip happened: the count of trips matters even when the volume is lost.
What counts as a drink
Every liquid counts, not just water. Coffee, tea, juice, soda, beer, wine, soup, and the milk on your cereal all go in the drinks column with a rough amount in millilitres. Use the size printed on the bottle or can when you have it, and estimate the rest: a standard mug is about 250 mL, a tall glass about 350 mL. Naming the drink matters as much as the number, because caffeine and alcohol change how fast your bladder fills.
Using the 0 to 4 urge scale
Next to each bathroom trip, write how strong the urge felt just before you went. 0 means no urge: you went just in case, out of habit or before heading out. 1 is a normal desire to go, with no urgency. 2 is urgency that came on and then passed. 3 is urgency where you barely made it in time. 4 means you couldn't make it in time and leaked before you got there. These are the same five levels the in-browser diary uses. Rate it in the moment rather than at the end of the day, because urgency is the column your clinician reads most closely.
How to record leaks
If you leak on the way to the toilet, write 4 in the urge column for that trip. That is the whole entry: no separate leak row is needed. If you leak at any other moment, for example when you cough, sneeze, laugh or lift something, give the leak its own row. Write the time, then fill in the three leak columns: what you were doing, how much leaked, and whether you felt an urge just before it. The codes for each column are in the key at the top of the sheet.
The wake and bedtime rows
The first and last rows of each day are anchors. In the wake row, write the time you got up and the volume of that first morning void, which is usually the largest of the day. In the bedtime row, write the time you settled down to sleep. Those two times let anyone reading the sheet separate daytime frequency from night-time trips, and they are what turn a list of entries into a proper 24 hour picture. When you get up the next morning, answer the question under the day: did you wet the bed during the night? After Day 3 there is one more box, the final morning: write your wake-up time, your first trip to the bathroom with its time, amount and urge level, and whether you wet the bed in the night. Day 3 is only complete once that box is filled in.
Why three days and not one
One day is a snapshot, and a single unusual day can be misleading. Three consecutive days smooth out the noise and let a weekday sit next to a weekend, which is when drinking, sleeping, and toilet access usually change most. Three days is also the length most clinics and guidelines ask for, so a completed three-day sheet is accepted as evidence rather than sent back. If three feels like too much, two completed days beat three half-finished ones.
When you are done
You have two options, and they are not exclusive. Type the numbers into the free in-browser diary and it works out your totals, your average voided volume, your night-time trips, and your fluid intake without you doing any arithmetic. Nothing you enter leaves your device. The in-browser diary does not ask about bedwetting, so if you wet the bed on any night, tell your clinician. Or simply fold the paper sheet into your bag and hand it over at your appointment, which is still perfectly good practice.
If you want more background before you start, the full bladder diary guide explains what each measurement tells a clinician, and the PDF versus in-browser comparison covers when a downloadable file is the better choice.
Common questions
How many days should a bladder diary be?
Three consecutive days is the usual answer, and it is what this sheet is built for. Shorter diaries of one or two days are still useful for spotting an obvious pattern, and some specialist clinics ask for up to seven days before a procedure. Ask your own clinic if you are unsure, because their form may have a fixed number.
Do I have to measure every single void?
Measuring every trip across all three days gives the most useful record, but a partial diary is far better than none. If measuring is impossible at work or away from home, note the time and the urge level, mark the volume as not measured, and measure the ones you can. Aim to capture at least the first morning void and the overnight trips, since those carry the most information.
Can I use this diary for my child?
This sheet is designed for adults, and the row spacing, the urge wording, and the volume expectations all assume an adult bladder. Children need age-adjusted normal volumes, and a child's bedwetting is usually recorded night by night over a full week. Ask your paediatrician or a paediatric continence service for the right form.
What do the numbers actually mean?
Volumes tell you how much your bladder holds before it asks to be emptied, and trip counts tell you how often that happens across the day and the night. Read together with the urge column, they show whether the problem is a bladder that fills too fast, one that signals too early, or a fluid habit that can be adjusted. Your clinician compares them against expected ranges rather than a single pass or fail number.
