This sheet only records the readings you take with your own meter or CGM. It does not tell you what your levels should be — write the target range your doctor or diabetes educator gave you in the space above.
How to use a blood sugar log sheet
- Step 1
Print a fresh sheet
Print one sheet per day, week or month depending on the layout, and keep it with your meter so it is there when you test.
- Step 2
Write every reading straight away
Record the value right after you test, in the column for that time of day. Readings written from memory later are the ones that end up wrong.
- Step 3
Bring it to your appointments
A complete log lets your doctor or diabetes educator see patterns across weeks instead of a single number on the day.
What to record in a glucose log
- Date and time
- Every reading needs a date and a time. Patterns only show up when readings can be lined up by time of day.
- The blood sugar value and its unit
- Write the number exactly as your meter or CGM shows it and tick the unit (mg/dL or mmol/L) once at the top so the whole sheet is consistent.
- Before or after a meal
- A reading before breakfast and one two hours after lunch mean different things. Mark which it was — the weekly layout has separate columns for each.
- Notes
- Unusual food, exercise, illness, stress, a missed dose or how you felt. Short notes are what make a log useful to your care team.
- Your target range
- Copy the target range your doctor or diabetes educator gave you into the box at the top. This sheet does not suggest a range — that is a decision for your care team.
The four log sheet layouts
Daily blood sugar log
Twelve rows for one day — waking, before and after each meal, bedtime, overnight and spare rows — with a time, a value, a before/after tick box and a notes column. Best if you test several times a day.
Weekly blood glucose log sheet
Seven days with fasting, before and after breakfast, lunch and dinner, and bedtime columns. The classic layout most clinics ask for.
Monthly glucose log
All 31 days on a single page with four readings per day and a notes column. Compact, so it suits people who test once or a few times a day.
Large-print blood sugar log
Bigger text, taller rows and only four columns per day — morning, midday, evening and bedtime — for anyone who finds standard tables hard to read or write in.
Rather keep your log on your phone?

Blood sugar log sheet FAQ
Is this blood sugar log sheet really free?
Yes. Choose a layout, click Print or save as PDF, and use your browser's print dialog. There is no sign-up, no email address to enter and nothing is uploaded — the sheet is generated in your browser.
How do I save the log sheet as a PDF?
Click Print or save as PDF, then in the print dialog choose “Save as PDF” (or “Microsoft Print to PDF” on Windows) as the destination instead of a printer.
Which layout should I use?
Use the daily sheet if you test many times a day, the weekly sheet for a before-and-after-meals overview, the monthly sheet for a compact 31-day record, and the large-print sheet if you find small tables hard to read or write in.
Does the sheet work for mg/dL and mmol/L?
Yes. Tick the unit you use at the top of the sheet and write your readings in that unit. If you need to convert a value, use the free mmol/L to mg/dL converter on this site.
What should my blood sugar readings be?
This page cannot tell you that. Target ranges depend on your type of diabetes, your treatment and your health, and they are set by your doctor or diabetes educator. The sheet gives you a space to write down the range they gave you.
Can I keep this log digitally instead?
Yes. DiabetLog is a free blood sugar tracker app for iPhone, iPad and Android that records the same information — value, time, before or after a meal, notes — and can generate a PDF report for doctor visits. Your data stays on your device.
