A photo of someone else that can be read fairly
The uploader on this page says "your face" because the same tool runs on every page. It still reads a photo of someone else. Use a picture you have the right to use: a friend who said yes, a partner who is in the room, or a family print you already share.
One clear face, looking at the camera, in light from the front, with no beauty filter, is the fair reading. Heavy makeup, a smoothing filter, sunglasses, a hat, or a face turned away all move the number. The card will still talk to the face as "you". That wording is on purpose: the estimator is told never to say he or she, and never to guess a name, even when the face looks famous.
- One face, large enough that the eyes, nose and mouth are easy to see. Crop everyone else out first.
- Facing the camera, near eye level, with light from the front rather than from the ceiling.
- A recent photo when you want today's look. An old print answers how that person looked then.
- The original file when you have it. A screenshot of a screenshot smears skin texture.
- No beauty filter and no portrait blur. Those erase the lines and texture the guess uses.
Why a room of friends lands on different ages
Friends are not neutral counters. Three published patterns explain most of the argument, before anyone uploads a thing.
People are sharper near their own age
A 2012 study asked 154 adults to estimate the age of 171 faces, each shown with several expressions. Young adults and older adults were more accurate, and less biased, on faces from their own age group than on the other group. A 25-year-old and a 60-year-old can both be careful and still disagree. The paper is Let me guess how old you are.
Makeup does not move every face younger
A 2019 experiment in the British Journal of Psychology compared controlled photos with and without makeup. Women around 40, and especially around 50, looked younger with makeup. Women around 30 looked about the same. Women around 20 looked older. A smoothing filter is a separate change from makeup, and this page does not treat them as one effect. The paper is Differential effects of makeup on perceived age.
A smile, and the face you just saw
In that 2012 study, happy faces were the expressions most often guessed younger than a neutral face. Clifford, Watson and White, using passport-style photos of 3,948 people and 84 perceivers, found an average error of about 8 years. Younger faces were guessed older, older faces were guessed younger, and a guess was pulled toward the age of the face just seen. Their paper is Two sources of bias explain errors in facial age estimation. A grinning close-up, right after everyone looked at a much older photo, is a noisy bet. Those 8 years describe that passport set, not a promise about this tool.
Settle the bet before anyone sees the number
A public age quiz shows a stranger, then reveals a birthday someone stored. That does not settle an argument about a photo you already have. Write the guesses down first, or the number on the screen will talk the room into it.
It works the same for a brother, a partner or a friend on the couch: whatever the photo, the written guesses have to exist before the upload.
- Agree whose photo it is, and that everyone in the room is allowed to see it.
- Each person writes one age, or a short range, where the others cannot edit it. A note on a phone is enough.
- Upload one crop. Read the range on the card before you argue about the single number. A written guess inside the range counts as a hit.
- The lines under the number name the cues that pulled it: skin texture, lines, the eye area, hair and hairline, face shape, skin tone, or facial hair. The report keeps the 3 to 5 cues that mattered most, each marked older, younger or neutral, plus 2 practical tips.
- One extra photo in the same light is a check. It becomes a new bet only if you said so before the first result.
- You get 10 free estimates a day from this browser, with no account. That covers a few crops and a second photo.
What this tool does with the picture
These rules are what the estimator on this page actually does. A group shot does not get a silent guess of whichever face is largest.
Two faces, or none
When two or more faces are clearly visible, the estimate stops and asks for a crop. It does not choose a person for you. When there is no human face, or the face is too small or cut off to judge, or the picture is a drawing, an animal or an object, it says it could not find a face.
Hard to read, versus merely imperfect
A face so blurred, dark or covered that the eyes, nose and mouth cannot be made out is refused. A small, grainy, old, slightly soft, badly lit, filtered or angled photo is still estimated, as long as the features can be seen. Confidence is marked low, the range is wider, and one cue says the photo limited the judgment.
The range on the card
The model is asked for one best age and a range that is usually 4 to 8 years wide. If a reply comes back wider than 20 years, the page pulls it in to 10 years on either side of the guess. If it comes back narrower than 2 years, the page widens it to 1 year on either side. Ages outside 1 to 100 are not shown. Confidence is low, medium or high.
Why the card says you
The sentences in the report talk to the face as you, including phrases like your hairline. The same instruction blocks he, she, a guessed name, and any comment on gender, ethnicity, health or attractiveness. Read the number as the apparent age of the person in the file.
Apparent age and a birthday are different questions
"How old is this person?" usually means a date of birth. "How old does this person look?" means what the face reads as. This page only answers the second question. Apparent age moves with light, expression, grooming and the lens. A birthday does not.
A profile picture is enough when the face is clear and alone. A photo of a screen, or a scan of a print, can run when the features are still visible. Expect the low-confidence label on grain, a strong color cast, or heavy compression. Before upload, the browser shrinks the long side to 1,024 pixels and re-encodes a JPEG, which drops location and camera data. Files up to 25 MB can be opened. The image is then analyzed in memory and never stored.
What the number must not decide
The result is for curiosity, and for a game everyone agreed to. It can be off by years. Do not use it to decide whether someone is an adult, to check an identity, or to make a dating-safety decision. Do not upload a photo of a minor unless you are their guardian.
If you wanted a scored round of strangers with a hidden birthday, that is a different kind of page. Here you bring a photo you already have, and there is no hidden real age to reveal. You still need the right to upload it. The share card is drawn on your device. The full path is in the privacy policy.
When the photo is your own face
This page is for someone else. For your own selfie, start at How Old Do I Look AI, or play guess my age with friends under the same light. An old print of yourself, and the checklist for a readable file, live on the age detector. The face age page separates apparent age, chronological age and biological age. The 10 free estimates a day are shared across these pages, because they call the same estimator.
Questions before you upload someone else's photo
How old does she look in a group photo?
Crop to one person and upload that crop. Two or more clear faces stop the estimate. The page will not pick the largest face and assign the number to that person.
Why does the card say I look a certain age?
The report addresses the face in the file as you. It does not switch to he or she, and it does not name the person. The number is the apparent age of whoever is in the photo.
Can a smile make the guess younger?
It can. In the 2012 study linked above, happy expressions were the ones most often guessed younger than a neutral face. For a bet about everyday life, use a relaxed expression in daylight.
Do you keep my friend's photo?
No. It is analyzed in memory and never stored. It is not written to disk, a database or a log. You still need permission to upload it. See the privacy policy.
Can we use a profile picture?
Yes, when one face is clear and you have the right to use the file. A heavy filter or a tiny crop is the usual reason for a low-confidence label, or for a refusal when the features cannot be made out.
How many tries do we get on one phone?
This browser gets 10 free estimates a day, with no account. Crop first so a group shot does not spend a run.
