We say “cheese” in photos because the sound of the word naturally pulls your mouth into a smile-like shape, and the habit stuck in English-speaking culture over the 20th century.

How “cheese” shapes your face

  • The long “ee” sound (like in “cheese”) pulls the corners of your mouth slightly upward, mimicking a light smile rather than a flat or neutral mouth.
  • Ending on the soft “s” helps you hold that mouth shape for a moment while the photo is taken, instead of your lips snapping closed right away.

So the word is less about dairy and more about quick, repeatable “smile engineering.”

When the phrase took off

  • The earliest widely cited reference to “say cheese” for photos in English traces to around the early–mid 1900s, including a 1940s U.S. newspaper tip that recommended saying “cheese” to create an automatic smile.
  • As snapshot cameras and casual family photography spread, this simple cue became standard instruction from photographers and parents, then turned into a cultural reflex.

Before that, people often looked serious in portraits, partly because of long exposure times and different style norms.

Do other languages use “cheese”?

Many other languages use completely different words that also force a smile shape.

  • In some places, people are asked to say words like “whiskey” or other local terms that put the mouth in a similar smiling position.
  • Some cultures focus less on a fixed word and more on getting a genuine laugh or natural expression, especially in modern, candid-style photography.

The idea— prompt a quick, camera-ready smile —is the same, even if the magic word changes.

Does “cheese” actually make better photos?

  • For some faces, “cheese” creates a pleasant, mild smile; for others, it can look a bit stretched or forced, which is why many photographers now prefer jokes or conversation over the classic prompt.
  • A lot of current advice in photography is to aim for genuine emotion rather than a formula word, especially for portraits and social media images.

If “cheese” makes your smile feel fake, you can try alternatives like “yay,” “hey,” or even just thinking of something funny. TL;DR: We say “cheese” because its sounds pull your mouth into a quick, easy smile, the phrase got popular in mid‑20th‑century English photography, and it stuck as a light, universal cue for grinning at the camera.
