What is an endometrial thickness scan?
It is a precise measurement of the endometrium — the lining of the womb — taken during a pelvic ultrasound, usually transvaginally because millimetres matter here. The lining is measured at its thickest point, the uterus and both ovaries are assessed at the same time, and the number is then interpreted against your life stage: strict thresholds after the menopause, cycle-dependent ranges before it, and different expected ranges again if you are on HRT. No preparation, no needles, no radiation.
Why might I need my endometrial thickness measured?
Three main reasons: bleeding after the menopause — any bleeding, however light, a year or more after periods stopped — which always warrants assessment; HRT monitoring, where the lining’s response to hormone therapy is periodically checked; and abnormal bleeding patterns in the years around the menopause, where the measurement helps separate hormonal noise from structural causes like polyps or fibroids.
The lining is measured precisely, in millimetres, usually transvaginally — the approach that gives the accuracy these decisions deserve. Further reading: postmenopausal bleeding — causes and next steps.
Any bleeding after the menopause should be on your GP’s radar, whether or not you book a scan — the measurement guides what happens next, but the referral pathway starts with them. Heavy bleeding with dizziness or severe pain is a same-day matter for A&E or NHS 111.

Is this scan suitable for me?
An endometrial assessment is the right booking if any of these sound like you:
- ✓You have had any bleeding since the menopause — even once, even light
- ✓You are on HRT and your lining is being monitored
- ✓Your bleeding pattern has changed in the perimenopausal years
- ✓A previous scan mentioned a thickened lining and you want it measured properly
And when it is not the right booking
Heavy bleeding with dizziness or severe pain — that is a same-day matter for A&E or NHS 111, not a scan booking.
You are already under a gynaecologist with a hysteroscopy booked — the measurement rarely changes that plan. Call us and we will say so honestly rather than take the booking.
If this is not the right test for you, we will say so before you book — not after.
What happens during the appointment?
Thirty minutes, and the sequence never varies — because knowing what comes next is most of what makes an intimate examination bearable.
- 1
The history comes firstWhen the bleeding started, how much, whether you are on HRT — taken seriously before the probe touches skin.
- 2
Transabdominal surveyThe uterus and ovaries assessed through the abdomen first, giving the overall picture.
- 3
Transvaginal measurementWhere it adds accuracy and only with your consent — a female chaperone present, the covered probe offered for you to insert yourself.
- 4
The number, in contextThe lining measured at its thickest point and explained on screen against the threshold that applies to you.
What does endometrial thickness mean at different life stages?
The same number means different things in different decades — which is why interpretation, not just measurement, is the service.
After the menopause
Thresholds are strict and the 4mm rule anchors everything. At or under 4mm with bleeding, the risk of significant pathology is very low and simple vaginal atrophy is the likeliest explanation.
Before the menopause
The lining changes dramatically across the cycle — thin just after a period, thick before one — so a premenopausal measurement is only meaningful against your cycle day, and we time and read it accordingly.
On HRT
Expected ranges shift with the regime. Your report states the number, the context and what it means for you — never a bare figure.
Understanding your result and next steps
Post-menopausal bleeding is always treated with high clinical suspicion — which is precisely why the appointment is built around one number. High suspicion in the process, calm honesty in the room.
How the report moves
Findings are explained on screen during the scan itself — you never leave wondering.
For post-menopausal bleeding the written report is issued same-day, deliberately, to keep the referral pathway moving. Routine monitoring reports arrive usually within two hours.
It is written for your GP to act on — the measurement, the context, and the recommended next step, stated plainly. See how results and reports work.
