Post-menopausal endometrial thickness depends on the woman's decision to use hormone therapy. The endometrium of a post-menopausal woman without medical intervention measures approximately 5 millimeters, but a woman on hormone replacement therapy has an endometrial thickness of 8 to 15 millimeters. Radiopaedia explains that a post-menopausal woman on Tamoxifen has an endometrial thickness less than 6 millimeters or greater than 8 millimeters.
