清楚、置中、正面的單人肖像
這類照片最有利於比較對稱、三庭、間距與比例線索。
- 單一臉部，雙眼與五官清楚可見
- 光線穩定、角度自然，避免重濾鏡
三庭比例計算器
三庭比例計算器，測量上庭、中庭與下庭平衡
從照片測量上庭、中庭、下庭，並取得平衡提示。 結果是娛樂與肖像參考，不是醫療建議或客觀魅力判定。
Upper third: visible forehead or hairline area to the brow zone.
Middle third: brow zone to nose base, closely related to midface balance.
Lower third: nose base to chin, affected by expression and mouth position.
Equal facial thirds are portrait references, not universal beauty requirements.

Use a centered front-facing portrait with the forehead or hairline, brows, nose base, lips, and chin as visible as possible for a steadier facial thirds test.

上傳照片範例與結果示意
上傳前先看這些圖文範例。清楚的正面照能幫助偵測器讀取臉部標記；角度、模糊或遮擋則可能讓結果不夠穩定。
不建議上傳
側臉、模糊、陰影或五官遮擋
如果關鍵點被遮住或變形，GoldenFace 仍會嘗試分析，但分數與指標說明可能較不穩定。
- 臉部大幅轉側或被裁切過緊
- 墨鏡、口罩、頭髮遮擋、低光或多人入鏡

Facial Thirds Calculator FAQ
What are facial thirds?
Facial thirds divide the visible face vertically into upper, middle, and lower zones to discuss balance in a portrait.
How do you measure facial thirds?
A common reference compares the upper face, brow-to-nose-base area, and nose-base-to-chin area. Photos can only estimate these zones from visible landmarks.
What is a facial thirds calculator?
It is a photo-based tool that estimates the three vertical face zones and explains whether they look close to equal in that image.
Why can facial thirds change between photos?
Hairline visibility, camera height, lens distance, expression, tilt, and landmark confidence can change the visible proportions.
Is this a beauty verdict?
No. Facial thirds are a portrait-composition reference, not a verdict on attractiveness or professional advice.
