TikTok Creator Calculations

TikTok File Size Calculator

Calculate file sizes for TikTok videos based on duration and quality settings.

Formula:

File Size (MB) = (Bitrate × Duration × 60) ÷ 8

Examples:

60-second video at 10 Mbps

Calculation: (10 × 1 × 60) ÷ 8 = 75 MB

Result: 75 MB file size

3-minute video at 8 Mbps

Calculation: (8 × 3 × 60) ÷ 8 = 180 MB

Result: 180 MB file size

Pro Tips:

  • Keep videos under 100MB for faster uploads
  • Use 8-10 Mbps bitrate for good quality/size balance
  • Compress longer videos to stay under 287MB limit

Vertical Video Aspect Ratio

Calculate proper dimensions for TikTok's 9:16 vertical format.

Formula:

Height = Width × (16 ÷ 9)

Examples:

720p vertical video

Calculation: 720 × (16 ÷ 9) = 1280

Result: 720×1280 resolution

1080p vertical video

Calculation: 1080 × (16 ÷ 9) = 1920

Result: 1080×1920 resolution

Pro Tips:

  • Always shoot in 9:16 for TikTok to avoid cropping
  • Use 1080×1920 for best quality
  • Avoid horizontal footage - it will be heavily cropped

Upload Time Calculator

Estimate upload times for TikTok videos based on file size and connection speed.

Formula:

Upload Time (seconds) = (File Size × 8) ÷ Upload Speed

Examples:

50MB video, 10 Mbps upload

Calculation: (50 × 8) ÷ 10 = 40 seconds

Result: 40 seconds upload time

100MB video, 5 Mbps upload

Calculation: (100 × 8) ÷ 5 = 160 seconds

Result: 2 minutes 40 seconds

Pro Tips:

  • Upload on WiFi for faster speeds
  • Compress videos for quicker uploads
  • TikTok processes videos after upload - allow extra time
