Countdown Timer Dimensions for Twitch (1920x1080)
Understanding countdown timer dimensions ensures your timer displays perfectly across all devices - from 4K monitors to mobile phones. This technical guide covers optimal resolutions, positioning, safe zones, and platform-specific requirements for flawless Twitch countdown timers.
Twitch Standard: 1920x1080 (Full HD)
Why 1920x1080 is the Standard
Twitch Streaming Reality:
Platform Distribution:
- 78% of Twitch streams: 1080p (1920x1080)
- 15% of Twitch streams: 720p (1280x720)
- 5% of Twitch streams: 1440p/4K
- 2% of Twitch streams: Sub-720p
Twitch Transcoding:
- Partners: Guaranteed transcoding (viewers choose quality)
- Affiliates: Priority transcoding (usually available)
- Non-affiliates: Transcoding when capacity available
What This Means:
- Stream at 1080p → Twitch creates 720p, 480p, 360p versions automatically
- Your 1920x1080 countdown looks good at all quality settings
- Mobile viewers get optimized version automatically
Verdict: 1920x1080 is optimal for Twitch. Higher resolutions rarely needed.
Full-Screen Countdown Dimensions
Option 1: Full Canvas (Recommended)
Dimensions:
Width: 1920 pixels
Height: 1080 pixels
Aspect Ratio: 16:9
File Size: 5-30 MB (depends on duration/compression)
When to Use:
- Starting Soon screens
- BRB screens
- Stream Ending screens
- Any full-screen countdown scene
OBS Setup:
Add → Media Source
Local file: countdown_1920x1080.mp4
Transform → Fit to Screen (or leave at source size)
Visual Coverage: Entire screen filled with countdown timer
Option 2: Centered Countdown with Custom Background
Countdown Video Dimensions:
Width: 1920 pixels
Height: 1080 pixels
Aspect Ratio: 16:9
But: Transparent or semi-transparent background, allowing OBS background to show through
Layer Structure in OBS:
Top: countdown_transparent.mp4 (timer only)
Middle: Text overlays, logo
Bottom: Background (image, color, or video)
Benefit: Maximum flexibility, reuse countdown with different backgrounds
Overlay Countdown Dimensions
Scenario: Timer Over Gameplay
Use Case: Countdown while gameplay visible (e.g., "Stream ending in 5:00")
Recommended Dimensions:
Large Overlay (Prominent):
Width: 800-1000 pixels
Height: 400-500 pixels
Position: Center or top-center
Medium Overlay (Noticeable but not obtrusive):
Width: 600-800 pixels
Height: 300-400 pixels
Position: Top-center or corner
Small Overlay (Subtle reminder):
Width: 400-600 pixels
Height: 200-300 pixels
Position: Top-right or bottom-right corner
Positioning Examples:
Top-Center (Most Common):
X: 960 (center, 1920/2)
Y: 100-150 (slight padding from top)
Top-Right Corner:
X: 1520 (1920 - 400 countdown width)
Y: 100
Bottom-Right Corner:
X: 1520
Y: 880 (1080 - 200 countdown height)
Safe Zones & Mobile Optimization
The Mobile Problem
Twitch Mobile App Reality:
Viewing Stats:
- 52% of Twitch viewership on mobile devices
- Mobile screens: ~6 inches diagonal
- Aspect ratio: Often 16:9, but cropped/zoomed
Mobile Cropping:
- Mobile app crops edges slightly
- Important content in outer 10% may be cut off
- Viewers also rotate phones, hold at angles
Solution: Use safe zones
Twitch Safe Zone Guidelines
Full Safe Zone (Critical Content):
Left edge: 96 pixels from left (5% margin)
Right edge: 96 pixels from right
Top edge: 54 pixels from top (5% margin)
Bottom edge: 54 pixels from bottom
Usable Safe Zone:
Width: 1728 pixels (1920 - 192)
Height: 972 pixels (1080 - 108)
Why 5% Margin:
- Accounts for mobile cropping
- Leaves room for Twitch UI elements (chat pop-up, etc.)
- Prevents important text being cut off
What Goes in Safe Zone:
- Countdown timer numbers (primary content)
- "Starting Soon" text
- Any critical information
- Social media handles
What Can Go Outside:
- Decorative elements
- Background designs
- Non-essential graphics
OBS Safe Zone Template
Creating Safe Zone Overlay:
1. Create Image in Design Software:
Photoshop/GIMP/Canva:
Canvas: 1920x1080px
Draw Rectangle:
Position: 96, 54
Size: 1728 x 972
Fill: Semi-transparent color (e.g., green 50% opacity)
Export as PNG: safe_zone.png
2. Add to OBS as Guide:
Add → Image
File: safe_zone.png
Layer: Top (above all sources)
Use during setup, then hide/delete before streaming
3. Position Countdown Within Safe Zone:
- Ensure countdown numbers fall within green area
- Adjust text overlays to safe zone
- Test visibility
Resolution Options: When to Use Each
720p (1280x720)
When to Use:
- Streaming at 720p (low-end PC)
- Want smaller file sizes (storage-limited)
- Testing/draft versions
Pros:
- Smaller file size (2-15 MB)
- Faster upload/download
- Lower OBS performance impact (marginal)
Cons:
- Lower quality if scaled up to 1080p
- Not optimal if streaming 1080p
Verdict: Use if streaming 720p. Otherwise, prefer 1080p.
1080p (1920x1080) ⭐ Recommended
When to Use:
- Standard Twitch streaming
- Most viewers on 1080p or mobile (gets downscaled)
- Balance of quality and file size
Pros:
- Industry standard
- Perfect for Twitch transcoding
- Looks great on all devices
- Reasonable file sizes (5-30 MB)
Cons:
- Slightly larger files than 720p (minimal issue)
Verdict: Default choice for 90% of Twitch streamers.
1440p (2560x1440)
When to Use:
- Streaming at 1440p (rare, requires high bandwidth)
- Want extra quality for YouTube repurposing
Pros:
- Higher quality for 1440p monitors
- Future-proofing
Cons:
- Larger file sizes (20-80 MB)
- Twitch compresses anyway (marginal visible improvement)
- Most viewers won't see difference
- Higher bitrate required (8000+ kbps)
Verdict: Overkill for Twitch. Use 1080p.
4K (3840x2160)
When to Use:
- Premium production for YouTube/recorded content
- Special event streams with professional production
Pros:
- Highest quality
- Extreme future-proofing
Cons:
- Massive file sizes (50-200+ MB per countdown)
- Twitch compresses heavily (no visible improvement over 1080p)
- Requires 4K canvas in OBS (performance hit)
- Bitrate requirements exceed Twitch recommendations (6000 kbps max for partners, 3500-5000 for non-partners)
Verdict: Not for live Twitch streaming. Use for YouTube pre-recorded content only.
Aspect Ratio Considerations
16:9 (Standard) ⭐
Resolution Examples:
- 1280x720 (720p)
- 1920x1080 (1080p)
- 2560x1440 (1440p)
- 3840x2160 (4K)
Why 16:9:
- Native Twitch aspect ratio
- Matches most monitors and TVs
- Mobile devices display correctly
- No black bars
Verdict: Always use 16:9 for Twitch.
4:3 (Old Standard) ❌ Avoid
Problem:
- Creates black bars (pillarboxing) on sides
- Looks dated and unprofessional
- Wastes screen space
When to Encounter:
- Old countdown templates designed for 4:3 monitors
Solution: Regenerate at 16:9 aspect ratio.
21:9 (Ultrawide) ❌ Avoid for Twitch
Problem:
- Twitch crops to 16:9
- Top/bottom black bars (letterboxing) on most viewers' devices
- Unusual and potentially distracting
Solution: Stick with 16:9 for Twitch compatibility.
Font Size Guidelines
Countdown Number Size
For Full-Screen Countdown (1920x1080):
Large (Recommended):
Font Size: 180-250pt
Height: ~500-700 pixels
Visibility: Readable from across room, perfect on mobile
Medium:
Font Size: 120-180pt
Height: ~350-500 pixels
Visibility: Good on desktop, acceptable on mobile
Small (Not Recommended):
Font Size: <120pt
Visibility: Poor on mobile, strains eyes
Rule of Thumb: Countdown numbers should occupy 30-50% of screen height for full-screen countdowns.
Supporting Text Size
"Starting Soon" or "Be Right Back" Text:
Font Size: 72-96pt
Height: ~200-270 pixels
Position: Above or below countdown numbers
Secondary Text (Chat prompts, social handles):
Font Size: 36-48pt
Height: ~100-135 pixels
Position: Bottom third or corners
Mobile Test: If you can't read it on a 6" phone screen from 1 foot away, it's too small.
Positioning Best Practices
Countdown Timer Placement
Option 1: Dead Center (Classic)
X: 960 (center)
Y: 540 (center)
Alignment: Center
Pros: Balanced, traditional, can't miss it
Cons: Can feel static
Option 2: Upper Center (Modern)
X: 960 (center)
Y: 350-400
Alignment: Center
Pros: Leaves room for supporting text/graphics below, more dynamic
Cons: None (most popular choice)
Option 3: Lower Third
X: 960 (center)
Y: 750-800

Common Dimension Mistakes
❌ Mistake 1: Wrong Aspect Ratio
Example: Using 1280x960 (4:3) timer on 1920x1080 (16:9) canvas
Result: Black bars on sides (pillarboxing) or stretched/squashed image
Solution: Always generate countdown in same aspect ratio as OBS canvas (16:9 for Twitch)
❌ Mistake 2: Timer Too Small
Example: 400x300px countdown on 1920x1080 canvas (centered)
Result: Tiny countdown, hard to see, especially on mobile
Solution: Countdown should be 600x400px minimum for overlays, or full-screen for Starting Soon scenes
❌ Mistake 3: Text Outside Safe Zone
Example: Social media handle at Y: 1050 (only 30px from bottom)
Result: Cut off on mobile devices
Solution: Keep all important text within safe zone (54px from edges)
❌ Mistake 4: Excessively High Resolution
Example: Using 4K (3840x2160) countdown on 1080p stream
Result:
- OBS scales down (quality loss in downscaling)
- Wasted file size
- No quality improvement visible to viewers
Solution: Match countdown resolution to stream resolution (1080p countdown for 1080p stream)
OBS Canvas & Output Settings
Matching Countdown to OBS Canvas
OBS Base Canvas (What you see in OBS):
Settings → Video → Base (Canvas) Resolution: 1920x1080
OBS Output Resolution (What viewers see):
Settings → Video → Output (Scaled) Resolution: 1920x1080
Best Practice: Base = Output = 1920x1080 for Twitch
Countdown Resolution: Also 1920x1080 (matches perfectly)
Downscaling Scenario
If Streaming 720p for Performance:
OBS Settings:
Base (Canvas): 1920x1080 (work in full res)
Output (Scaled): 1280x720 (stream lower res for bandwidth)
Downscale Filter: Lanczos (best quality scaling)
Countdown Resolution: Still 1920x1080
Why: OBS scales down along with all other sources. Working in 1080p gives best quality, then OBS handles downscaling efficiently.
Platform-Specific Considerations
Twitch
Optimal: 1920x1080, 30fps minimum, H.264 MP4
Bitrate: 3000-6000 kbps (countdown doesn't need full 6000)
Special Notes: Use safe zones for mobile viewers (52% of audience)
YouTube (If Multi-Streaming)
Optimal: 1920x1080 or higher (2560x1440, 3840x2160)
Bitrate: 4500-9000 kbps
Special Notes: YouTube favors higher quality. If multi-streaming to YouTube + Twitch, 1080p works for both.
Facebook Gaming
Optimal: 1280x720 or 1920x1080
Bitrate: 4000 kbps max
Special Notes: Similar to Twitch. 1080p countdown works well.
Conclusion
