CTV Creative Specs: Designing for the Living Room

Your web designer just handed you a “TV commercial.” It looks great on their monitor. It’s going to be unreadable on a 55-inch screen viewed from the couch.

CTV creative follows different rules than digital display. The viewing distance is 8-10 feet, not 18 inches. The screen is 40-65 inches, not 6 inches. The viewer is leaning back, not leaning forward.

This guide covers the technical specifications that separate professional CTV creative from repurposed web video. For the broader creative strategy, see the law firm CTV creative strategy guide.

The 8-Foot Problem

Web content is designed for arm’s length. CTV content is designed for across the room.

Everything about CTV creative (font size, contrast, pacing, information density) must account for this difference.

Resolution and Format

Standard CTV Specs

Specification	Requirement
Resolution	1920×1080 (1080p)
Aspect Ratio	16:9
Frame Rate	23.98, 24, 25, or 29.97 fps
File Format	MP4 (H.264) preferred

What to Avoid

• Letter-boxing or pillar-boxing. Fill the entire screen.
• Anamorphic scaling. Maintain proper aspect ratio.
• Slates or countdowns. CTV platforms don’t need them.
• Low bitrate. Encoding artifacts are visible on large screens.

MNTN’s spec guide emphasizes: your ad appears alongside premium content. It needs to match that quality level.

Font Sizes for TV Viewing

There’s no universal “legal” font size for CTV, but industry best practices have converged on clear minimums.

Recommended Sizes (1920×1080 canvas)

Text Type	Minimum Size	Recommended
Body text	60px	70px+
Headlines	90px	100px+
Phone numbers	80px	100px+
URLs	70px	80px+
Legal disclaimers	40px	50px+

Why This Matters

At 8-10 feet on a 55-inch TV, text that looks fine on your monitor becomes illegible. The viewer won’t squint. They’ll ignore it.

Test your creative on an actual TV screen at viewing distance before approval.

Contrast Requirements

The Standard

While CTV platforms don’t enforce a specific ratio, accessibility guidelines (WCAG AA) provide a reliable baseline:

Text Type	Minimum Contrast Ratio
Normal text	4.5:1
Large text (24px+ or 18.5px bold)	3:1

Why Contrast Matters on TV

• TV displays vary in calibration
• Living room lighting varies (daylight, lamps, dark)
• Compression artifacts reduce clarity
• Low contrast = unreadable at distance

High contrast isn’t just accessible. It’s legible.

Colors That Fail

• Light gray on white
• Yellow on white
• Light blue on medium blue
• Any low-contrast combination that “looks fine” on a calibrated monitor

Safe Zones

What’s a Safe Zone?

The area inside the frame where text and logos won’t be cut off by TV bezels, overscan, or UI overlays.

Netflix/Industry Standard (1920×1080)

Edge	Inset	Pixels
Top	3.5%	38px
Bottom	3.5%	38px
Left	3.5%	67px
Right	3.5%	67px

Safe Zone Rules

• All text must be inside the safe zone
• Logos must be inside the safe zone
• Phone numbers and URLs must be inside the safe zone
• Critical visual elements should be inside the safe zone

Background imagery can extend to the edges, but anything the viewer needs to read or recognize should stay inside.

Logo Placement

Best Practices

1. Logo in first 3 seconds. Brand recognition before anything else.
2. Persistent logo. Small, in a safe corner, throughout the spot.
3. End card logo. Larger, with CTA, final frame.

Positioning

Placement	Use Case
Bottom right	Most common, least intrusive
Bottom left	Alternative if CTA is right-aligned
Top corners	Less common, can feel like a bug

Size

• Persistent logo: Small enough to not distract, large enough to recognize
• End card logo: Prominent, paired with phone/URL

CTA Requirements

The Dual CTA Rule

CTV viewers can’t click. They can:

1. Remember and search later
2. Pick up their phone and call
3. Pick up their phone and type a URL

Every CTV spot needs both spoken and on-screen CTAs.

On-Screen CTA Specs

Element	Duration	Size
Phone number	3+ seconds	80-100px
URL	3+ seconds	70-80px
”Call Now” / “Visit”	3+ seconds	60-70px

Why Duration Matters

The viewer needs time to:

1. See the CTA
2. Process it
3. Decide to act
4. Pick up their phone

A phone number that flashes for 1 second is wasted real estate.

What Doesn’t Work on CTV

Repurposed Web Video

• Too small (designed for mobile)
• Too text-heavy (designed for reading)
• Wrong pacing (designed for skip)
• Sound-optional (CTV is sound-on)

Repurposed Broadcast Creative

Sometimes works, but watch for:

• Legal disclaimers in 12px font
• Outdated phone numbers or URLs
• Quality issues from format conversion

Social Media Creative

• Vertical or square format
• Text-heavy (designed for sound-off)
• Fast cuts (designed for thumb-stop)
• Wrong tone (casual vs. premium environment)

CTV vs. Web: Quick Reference

Element	Web/Display	CTV
Viewing distance	18 inches	8-10 feet
Font minimum	14-16px	60-70px
Contrast	4.5:1 (ideal)	4.5:1 (required)
Sound	Often off	Always on
Click CTA	Yes	No
Duration	6-15 seconds	15-30 seconds
Format	Various	16:9, 1080p

Pre-Flight Checklist

Before submitting CTV creative, walk through every step.

The Full System

CTV creative is the first impression, but it’s not the whole system. What happens after the spot matters just as much.

Frequently Asked Questions

What resolution should CTV ads be?

1920x1080 (1080p) in 16:9 aspect ratio is the standard. Frame rates of 23.98, 24, 25, or 29.97 fps are accepted. Avoid letter-boxing, pillar-boxing, or anamorphic scaling.

What font size is readable on CTV?

For a 1920x1080 canvas viewed at 8-10 feet, use 60-70px minimum for body text and 90-100px+ for headlines. Phone numbers and URLs should be 80-100px to ensure readability.

What is the safe zone for CTV ads?

The safe zone is a 3.5% inset from all edges, approximately 38 pixels from top/bottom and 67 pixels from left/right on a 1920x1080 canvas. All text and logos must stay inside this area.

How long should CTAs be visible on screen?

Phone numbers and URLs should be visible for at least 3 seconds. Viewers need time to see, process, and act. A CTA that flashes for 1 second is ineffective.
