Video QR Code Size Calculator
Calculate recommended pixel dimensions, on-screen display duration, and safe-zone placement for QR codes in YouTube videos, livestreams, slide presentations, and living room TVs.
* Note: Amber areas indicate potential platform overlays (YouTube scrubber, TikTok right buttons). Always keep the QR code out of these regions.
Viewer & Screen Parameters
Desk-seated viewer working or studying on a portable computer.
Shorter dynamic destinations produce fewer, chunkier dots that scan faster on video screens.
Renders at ~12 cm (4.7 in) on target display. Allows rapid, one-shot camera recognition.
Hard optical threshold. Below this, video compression artifacts and smartphone focal distance cause scan failures.
Viewers need time to notice the QR, reach for and unlock their phone, launch camera, aim, and wait for autofocus recognition.
- Assumes target display has approx. 15" diagonal (330mm width).
- Viewing distance modeled at 0.8 meters (2.6 feet).
- QR payload modeled at LOW density (~25×25 module grid). Shorter dynamic URLs require fewer dots.
- Allocates ~27.9 pixels per module to protect against H.264/H.265 compression blur.
- Moving video behind the QR code can distort corner detection. A solid backing plate is strongly advised.
- Backing Plate Note: Live video movement behind QR modules degrades scan reliability.
Planning recommendation based on optical scanning geometry. Real-world scanning speed depends on viewer phone sensor, ambient lighting, YouTube bitrate, and compression.
Publishing QR codes in your videos?
Your video can stay online for years—your sponsor link doesn't have to. Put one HoldQR dynamic QR in your video timeline, and update the destination anytime without re-rendering footage.
How to Size & Place QR Codes in Video
1. Select Video Canvas & Viewing Context
Choose from 1080p, 4K, 9:16 Shorts, OBS streams, or TV presets, and specify expected viewing distance (laptop, desktop, or living room couch).
2. Check Placement & Overlay Safe Zones
Ensure your QR code does not collide with platform player controls, YouTube scrubber bars, or TikTok right-rail action icons.
3. Calculate Pixels & On-Screen Timing
Receive exact pixel dimensions that survive video compression and recommended display duration (10–15s minimum) before exporting your timeline.
Frequently Asked Questions
How big should a QR code be in a 1080p YouTube video?
For standard 1920×1080 YouTube video viewed on laptops or desktops, a QR code should be at least 150×150 pixels (minimum) and ideally 200×200 to 240×240 pixels (recommended) for effortless, rapid scanning. For viewers watching on living room TVs from a couch (2.5–3 meters away), the QR code should be scaled to at least 450–600 pixels or larger.
How long should a QR code stay on screen in a video?
We recommend displaying the QR code for at least 10 to 15 seconds. Human scanning involves a sequence: roughly 2.5 seconds to notice the QR, 3.5 seconds to reach for and unlock a smartphone, 3.5 seconds to open the camera and frame the screen, and 1.5 seconds for optical recognition. Always keep the QR code completely stationary while displayed.
Can someone scan a QR code from a video playing on their phone?
A phone generally cannot conveniently use its camera to scan a QR code displayed on its own screen. For viewers watching on mobile devices, always provide a clickable URL in your video description or pinned comment. QR codes in video are most effective when viewed on TVs, laptops, desktop monitors, or projectors.
How do I add a QR code into Premiere Pro, DaVinci Resolve, or Final Cut Pro?
1) Download your high-resolution dynamic QR code from HoldQR (with a solid backing plate or transparent background). 2) Import the image file into your video editing software. 3) Place it on a video track above your footage, position it in a safe corner, and scale to the recommended pixel size. 4) Ensure it remains completely stationary on the timeline for at least 10–15 seconds. 5) Export and perform a test scan on your target screen.
What happens when a sponsor campaign expires?
With HoldQR dynamic QR codes, you never have to edit or re-render your video. Simply log in to your HoldQR dashboard and change the destination URL to your new sponsor, merch store, online course, or newsletter. The published video continues to send viewers to your active campaign forever.
