Specification	Value	Why It Matters	Optimization
Resolution & Specs
Upload Resolution (Recommended)	`1080 × 1920 px`	Sharp on all mobile screens; standard Full HD vertical.	Pro Tip Design at this size, export at this size.
Upload Resolution (High Quality)	`1440 × 2560 px`	Extra detail for high-PPI phones (iPhone Pro, Galaxy Ultra).	Pro Tip Use as source file; downscale to 1080×1920 for final upload.
Upload Resolution (Maximum)	`2160 × 3840 px (4K)`	Maximum source quality; must compress aggressively to stay under 2MB.	Pro Tip Only if you have advanced compression workflow; overkill for most.
Aspect Ratio	`9:16 (Vertical)`	Matches mobile screen orientation; fills entire phone display.	Pro Tip Never deviate; 4:5 or 1:1 crops will look broken in Shorts feed.
Orientation	`Portrait`	Portrait = thumb-scrolling optimized; landscape gets black bars.	Pro Tip If your source is landscape, pillarbox (black bars) = death for CTR.
Max File Size	`2 MB`	YouTube hard limit; exceeding = upload rejected.	Pro Tip Use TinyPNG or Squoosh to compress without visible quality loss.
Accepted Formats	`JPG, PNG, GIF, WebP`	JPG best for photos; PNG for graphics with transparency.	Pro Tip WebP offers best compression but test compatibility first.
Color Profile	`sRGB`	Ensures color consistency across iOS, Android, and desktop.	Pro Tip Adobe sRGB IEC61966-2.1 is the standard export preset.
Minimum Width	`600 px width`	Below this, YouTube may reject or severely compress.	Pro Tip If your design is 720×1280, upscale with bicubic sharper before upload.
Display Contexts
YouTube Display: Shorts Feed	`1080 × 1920 px (full vertical)`	Primary viewing context; thumbnail = first 1–2 seconds of video.	Pro Tip Thumbnail IS the hook; first frame must be as polished as custom thumbnail.
YouTube Display: Channel Page	`1080 × 1920 px (cropped to 1:1)`	Profile grid may crop to square; plan center-focused content.	Pro Tip Design a center-safe version (1:1 crop) for profile grids.
YouTube Display: Sub feed	`1080 × 1920 px (full vertical)`	Full vertical scroll; thumbnail must stop the thumb.	Pro Tip Use motion + freeze-frame technique: action in frame 1, hold for 0.5s.
YouTube Display: Search	`1080 × 1920 px (full vertical)`	Competes with other vertical results; contrast is king.	Pro Tip Add bold top text; search results show top 60% of vertical frame.
YouTube Display: Notification	`540 × 960 px (reduced preview)`	Small popup; key info must be instantly readable.	Pro Tip Notification images are tiny; rely on color + shape, not text.
YouTube Display: Embed	`Variable; cropped to 9:16 or 4:5`	External sites may crop unpredictably; keep content centered.	Pro Tip Always test embed by sharing link to yourself on Twitter/X or iMessage.
Safe Zones
Safe Zone: Top 15%	`Avoid critical text/UI elements`	Phone status bar, time, battery may overlap here.	Pro Tip Keep 120px margin from top edge completely clear.
Safe Zone: Center 70%	`Primary content zone`	Where eyes naturally rest while thumb-scrolling.	Pro Tip Place your face, product, or hero object dead center vertically.
Safe Zone: Bottom 15%	`Avoid critical text`	YouTube auto-captions, music info, and links appear here.	Pro Tip Keep 150px margin from bottom edge clear of critical content.
Danger Zone: Top-Right	`YouTube menu dots (⋮)`	Three-dot menu icon sits here; don't place text behind it.	Pro Tip Reserve top-right 80×80 px zone for UI safety.
Danger Zone: Bottom-Right	`Engagement UI`	Engagement buttons (like, comment, share) block this zone.	Pro Tip Reserve bottom-right 200×150 px zone for engagement UI safety.
Design Rules
Text Size (Minimum)	`72 pt on 1080×1920 canvas`	Readable when Shorts feed scales down on smaller phones.	Pro Tip Test by shrinking to 270×480 (25% scale) — still readable?
Text Size (Recommended)	`120–150 pt on 1080×1920 canvas`	Visible at a glance during fast scroll; no squinting needed.	Pro Tip Bold sans-serif only (Montserrat Black, Impact, Bebas Neue).
Text Words (Max)	`3–4 words maximum`	Shorts viewers scroll fast; 3 words = 0.5 second read time.	Pro Tip Use numbers: 'Day 1', '$0 to $10K', '3 Ingredients'.
Face Size (Recommended)	`40–50% of frame height`	Large enough to read emotion even at reduced preview sizes.	Pro Tip Fill 40–50% of vertical height; too small = emotion lost.
Face Position	`Center or upper-center`	Top third = where eyes land first in vertical scrolling.	Pro Tip Eyes should sit at golden ratio (~38% from top of frame).
Background Style	`Solid color or subtle gradient`	Busy backgrounds compete with text; simplicity wins.	Pro Tip Use brand color + 1 accent; max 3 colors total.
Contrast Requirement	`High contrast essential`	Low contrast = invisible in the feed; kills CTR.	Pro Tip White text on black bg = 21:1 contrast ratio (WCAG AAA).
Export & Workflow
Export Quality	`JPG 85–90% quality`	Higher quality = larger file; 85–90% is the sweet spot.	Pro Tip Export PNG if text-heavy; JPG if photo-heavy.
File Naming	`shorts_thumbnail_YYYYMMDD.jpg`	Organized workflow; version control for A/B testing.	Pro Tip Keep originals in /source/ and exports in /upload/ folders.
Account Requirement	`Phone-verified account required`	Unverified accounts cannot upload custom Shorts thumbnails.	Pro Tip Verify immediately in YouTube Studio → Settings → Channel → Feature eligibility.

The Perfect Vertical Checklist

Is the crazy Claude Code artifact instantly recognizable to viewers?

Did you keep the secret Python script strictly off right?

Does the crop perfectly frame your AI terminal action center?

Is your prompt tutorial text safely above the bottom captions?

Did you match the futuristic dark mode aesthetic perfectly today?

Have you completely eliminated any messy pillarboxing from the frame?

Vertical Psychology

Claude Code content dominates when using incredibly sleek dark mode backgrounds like a deep charcoal #1E1E1E or a glowing neon orange #D97757 to signal pure futuristic intelligence. Using warm or muddy shadows will completely kill your modern aesthetic vibe and cause a massive spike in rapid drops. These sharp color shifts trigger an immediate sensation of innovation that physically forces the viewer to stop scrolling. Keeping your text bright while the terminal interface stays intensely dark ensures your secret software aggressively stands out. Dialing in this exact contrast makes sure your prompt reveal pops beautifully while remaining safely positioned.

Strategy Note

Building a recognizable Claude Code brand requires sticking to a consistent, neon-lit vertical layout so fans instantly know it is your genius prompt hack. Always use the exact same bold, futuristic font for your text so the vibe stays uniform. Hitting perfect safe zones consistently makes your tech channel look insanely professional and highly bingeable.

Claude Code Shorts FAQ

Why use an auto-crop?

Using an extraction engine perfectly frames your chatbot tutorial for a vertical ratio without losing crisp text quality. It ensures your prompts stay centered to grab attention fast before the viewer decides to swipe away from your AI programming video.

How to avoid UI buttons?

You must keep your valuable prompt codes, terminal responses, and text overlays strictly on the left side and top third of your screen. This strategic placement avoids dangerous right-side engagement buttons that ruin your visual hook and tank watch time.

Are black bars really bad?

Yes, they completely ruin the premium tech aesthetic of your Claude Code vlog and scream sheer laziness to your audience. Eradicating pillarboxing keeps the viewer immersed, prevents rapid drops in attention, and significantly boosts overall channel credibility and daily subscriber growth.

What triggers a fast swipe?

A cluttered first frame, bad screen recording resolution, or prompt text hidden by the native interface will instantly trigger a swipe. You have exactly one second to deliver a satisfying dopamine hit, so your AI hook must be totally unobstructed.
