Should the subject be centred?

In a tall frame, usually yes. Off centre placement that reads as considered in a wide picture reads as a mistake in a narrow one.

Where do the eyes go?

Around the upper third, which leaves the space below free for the words.

Does this apply to square?

1:1 sits between the two, and the original rule holds up better there than in 9:16.

What about two people?

Split screen on paid plans gives each person their own tall frame, so the same reasoning applies inside each half.

Can I position the crop myself?

The framing tracks whoever is speaking rather than being placed by hand. What you choose is the shape and the template, and how you recorded sets the rest.

The Rule of Thirds in a Vertical Frame

Does the rule still apply when the frame is tall?

Partly. The horizontal thirds lose most of their value, because a narrow frame has little room to place a subject off centre without pushing them towards an edge. The vertical thirds gain value, because deciding how high the face sits is the main composition decision a tall frame offers.

Which thirds still do work

The rule was written for pictures wider than they are tall. Rotate the frame and half of it stops applying while the other half matters more.

Line	In a wide frame	In a tall frame
Horizontal thirds	Where the horizon or eyes sit	Still useful, this is the main decision
Vertical thirds	Where the subject sits left or right	Little room, off centre reads as an error
Upper intersection	Classic placement for a face	Still works
Lower third	Graphics and captions	Words, and it is the strongest use
Dead centre	Often avoided	Usually correct, there is nowhere else

Using the upper third for the eyes

In a vertical frame, placing the speaker's eyes near the line one third from the top gives a natural, comfortable look. It leaves room below for the body and gestures and keeps the face clear of the lower area, where subtitles and app controls usually sit.

If the eyes sit too low, the frame fills with empty space above the head and the subtitles creep onto the chin.

Leaving room in the direction of the gaze

When a subject looks or points to one side, a little extra space on that side feels balanced. In a narrow frame the effect is subtle, but even a small shift makes a clip look more deliberate.

For subjects facing the camera directly, centring usually works best in vertical video.

Placing text by the same logic

The thirds also help decide where words go. A hook near the top third line and subtitles near the bottom third line leave the middle for the face. Keeping those positions consistent across clips makes a series look planned.

Check that neither text area overlaps with interface elements on the apps you post to.

When to break the rule

Close-ups, symmetrical scenes and clips where the subject fills the frame often look better centred. The rule is a guide for balance, not a requirement.

Trust what looks right on a phone over what a grid suggests.

Compose for the shape you are posting

Use the horizontal thirds for height. Where the eyes sit vertically is the decision that still matters.
Centre the subject horizontally. A narrow frame has no room for a subject placed off to one side.
Leave the lower third for words. It is where text is most readable and where a face is least needed.

Run a clip and look at where the face sits vertically.
