What Are Lower Thirds? The Complete Guide to On-Screen Name Graphics (2026)

A lower third is a text-and-graphic overlay placed in the lower portion of the video frame — usually the bottom third — that identifies who is speaking, the topic, or the location. The classic example is a name and job title that slides in during an interview: "Jane Doe / CEO, Acme." It is called a "lower third" because it occupies roughly the bottom third of the screen, kept clear of the very edges so it stays inside the title-safe zone.

Lower thirds are one of those things every viewer has seen ten thousand times and almost nobody can name. They are also one of the fastest ways to make a video look professional — or, done wrong, amateur. This guide covers the anatomy, the broadcast origin, the safe-zone rules that trip people up, timing, the special case of vertical video, and how AI now generates lower thirds automatically. Short version lives in the lower thirds glossary entry.

What is a lower third?

A lower third is a graphic overlay in the lower area of the screen that displays supporting information without interrupting the main footage. Most often it introduces a person: their name on one line, their role or affiliation on a second. But it can also label a location ("Tokyo, Japan"), a topic ("Chapter 2: Pricing"), or a source ("Source: 2026 Creator Report").

The defining trait is that it is supplementary and temporary. It appears, delivers a piece of context, and leaves — usually within a few seconds. It sits on top of your A-roll without replacing it, so the viewer keeps watching the speaker while absorbing who they are.

Lower thirds are a staple of interviews, news, documentaries, YouTube videos, webinars, corporate content, and increasingly short-form social clips. They do a lot of quiet work: they build authority ("this person is an expert"), aid navigation ("we've moved to a new section"), and add polish that signals production value.

Where the name "lower third" comes from

The term is literal and comes from broadcast television. Imagine the screen divided into three horizontal bands: the "lower third" is the bottom band. Graphics identifying speakers were placed there because it kept the person's face — usually in the middle and upper portions — unobstructed.

In broadcast, these graphics were (and still are) often called a chyron — after the Chyron Corporation, whose character-generator hardware became so dominant in newsrooms that the brand name became the generic word, like Xerox or Kleenex. So "chyron," "lower third," "name super" (superimposition), "name strap," and "banner" all describe roughly the same thing, with regional and industry variations. If you hear a news producer say "put up the chyron," they mean the lower third.

The reason the bottom third specifically became standard is partly composition (faces sit higher) and partly the safe zone rules of old CRT televisions — which still matter today, as we'll see.

Anatomy of a lower third

A well-built lower third has a small number of consistent parts. Understanding them helps you design your own or evaluate a template.

The hierarchy matters most: the viewer's eye should hit the name first, then the title. If both lines are the same size and weight, the graphic reads as a wall of text and nobody registers either line.

Lower third vs chyron vs caption vs title card

These get used interchangeably but describe different things:

The key distinction: a lower third identifies, while a caption transcribes. They can appear at the same time, which is exactly why safe-zone stacking (below) matters — you don't want your lower third colliding with your captions.

Title-safe and action-safe zones (the rule everyone breaks)

Here is the single most useful technical concept for placing lower thirds: safe zones.

Old CRT televisions cropped the edges of the broadcast signal unpredictably (a practice called overscan), so broadcasters defined two margins:

• Action-safe zone — roughly the inner 93-95% of the frame. Keep all important action inside this.
• Title-safe zone — roughly the inner 90% (about a 10% margin on each edge). Keep all text and graphics inside this.

Even though modern screens rarely overscan, the title-safe zone survives for a better reason: text jammed against the edge of the frame looks cramped and unprofessional, and it can be clipped by phone notches, platform UI (the TikTok caption, the like/share buttons), rounded corners, or a viewer's player chrome.

So a lower third should sit in the bottom third but inside the title-safe margin — not touching the bottom or left edge. And it should sit above the area where captions and platform UI live. Getting this wrong is the #1 reason DIY lower thirds look off.

Timing: how long should a lower third stay on screen?

The rule of thumb: long enough to read twice, comfortably. For a name-and-title lower third, that is usually 4-7 seconds of full on-screen time (not counting the animation in and out).

Practical guidance:

• Introduce, don't overstay. Show the lower third shortly after the person starts speaking, hold it long enough to read, then animate it out. Leaving it up the entire clip is distracting and dates the footage.
• Re-introduce after long gaps. If a speaker returns after several minutes or after a section break, bring their lower third back briefly.
• Match the pace of the edit. Fast, punchy short-form clips use quicker lower thirds (2-4s); slow documentaries can hold longer.
• Animate with intention. A 0.3-0.5s ease-in and ease-out feels professional. Instant pop-ons feel cheap; slow 2-second crawls waste attention. This is where easing does the heavy lifting.

Lower thirds for vertical video (they don't stay in the same place)

This trips up creators repurposing horizontal content: in vertical 9:16 video, the "lower third" is not in the same spot as in 16:9.

On a vertical phone screen:

• The bottom ~20-25% is occupied by platform UI — the caption, username, sound name, and the like/comment/share buttons on TikTok, Reels, and Shorts.
• Captions are often placed center-ish, not at the very bottom, for the same reason.
• A lower third pushed to the literal bottom third will collide with all of that.

So when converting 16:9 to 9:16, you can't just crop and keep the lower third where it was. It needs to be repositioned higher (often to the lower-middle) and frequently resized, so it clears the platform chrome and doesn't fight the captions. Smart aspect-ratio reframing handles this automatically; manual center-cropping does not, which is why re-used graphics so often end up half-hidden behind a TikTok username.

How to create a lower third

You can build a lower third by hand in any editor, or generate one automatically. Here is the manual process, which also explains what the automated version is doing.

Step 1: Decide what information it carries

Usually a name and a title. Keep it to two lines. If you need more than that, it is probably a title card, not a lower third.

Step 2: Establish a clear hierarchy

Make the primary line (the name) noticeably larger and bolder than the secondary line. Pick a legible font — clean sans-serifs read best at small sizes and on mobile.

Step 3: Add a background for legibility

Because footage behind the text varies from dark to bright, add a bar, panel, gradient, or subtle shadow so the text stays readable over anything. A common failure is white text that vanishes over a bright background.

Step 4: Place it inside the title-safe zone

Position it in the bottom third but keep a ~10% margin from every edge, and leave room below for captions and platform UI.

Step 5: Animate the entrance and exit

Add a short slide or fade in, and a matching exit, using eased keyframes so it feels smooth rather than mechanical. 0.3-0.5s each way is a safe default.

Step 6: Match it to your brand

Use your brand colors, fonts, and logo so every video's lower thirds look like a set, not a grab-bag. Save it as a template so you never rebuild it.

Common lower third mistakes

Most bad lower thirds fail on legibility, placement, or restraint:

• No background bar or shadow. Text disappears over busy or bright footage.
• Touching the frame edge. Ignoring the title-safe margin makes it look cramped and risks clipping.
• Same size for both lines. No hierarchy means the viewer registers neither line.
• Leaving it up too long. A permanent name tag is distracting and looks amateur.
• Colliding with captions or platform UI. Especially in vertical — the lower third ends up behind the TikTok username.
• Overdesigned animation. Bouncing, spinning, 2-second reveals draw attention to the graphic instead of the person.
• Inconsistent styling. Different fonts, colors, and positions across a video read as sloppy.
• Unreadable fonts at small sizes. Thin or decorative fonts turn to mush on a phone.

How AI generates lower thirds

Lower thirds are highly automatable because the two hardest manual steps — knowing who is speaking and when — are exactly what AI speaker detection already solves.

Modern AI video editors can detect each speaker, and once you've labeled a speaker's name and title once, automatically place a correctly-timed, on-brand lower third every time that person begins speaking — introducing them, holding for a readable duration, and animating out. The same system can reposition the graphic for vertical exports so it clears platform UI.

In Loopdesk (disclosure: Loopdesk is our product), this fits into the wider multicam and podcast workflow: speaker detection drives both camera switching and speaker identification, so lower thirds, captions, and layouts all key off the same understanding of who's on screen. You direct it in plain English — "introduce each guest with a lower third the first time they speak" — instead of hand-keying graphics. For where this sits in the broader edit, see the video editing process, since lower thirds belong to the titles-and-graphics finishing stage. Lower thirds are one entry in the full video editing terminology guide.

Frequently Asked Questions

What is a lower third in video?

A lower third is a text-and-graphic overlay placed in the lower portion of the frame that identifies a speaker, topic, or location without interrupting the footage. The classic example is a name and job title that appears during an interview.

Why is it called a lower third?

Because it occupies roughly the bottom third of the screen. The screen is imagined as three horizontal bands, and this graphic lives in the lowest one — placed there historically to keep the speaker's face unobstructed and to respect TV safe zones.

What is the difference between a lower third and a chyron?

They describe the same thing. "Chyron" is the broadcast term, named after the Chyron Corporation whose character generators dominated newsrooms; the brand became the generic word. "Lower third" is the more common term outside broadcast.

How long should a lower third stay on screen?

Long enough to read comfortably twice — usually 4-7 seconds of full on-screen time for a name and title, plus a short animation in and out. Fast short-form clips use quicker lower thirds; slow documentaries can hold longer.

Where should a lower third go in vertical video?

Higher than in horizontal video. In 9:16, the bottom 20-25% is covered by platform UI (captions, username, buttons), so a lower third should be repositioned to the lower-middle and often resized so it clears that chrome and doesn't collide with captions.

What is the title-safe zone?

The title-safe zone is roughly the inner 90% of the frame (a ~10% margin on each edge) where text and graphics should stay to avoid being clipped or looking cramped. Keeping lower thirds inside the title-safe zone is a core rule for professional-looking graphics.

Can AI create lower thirds automatically?

Yes. AI speaker detection can identify who is speaking and when, so once you label a person's name and title, the editor can automatically place a correctly-timed, on-brand lower third each time they start speaking — and reposition it for vertical exports.
