Frequently Asked Questions
What are the correct dimensions for a YouTube thumbnail?
YouTube recommends thumbnails at 1280×720 px (HD) with a 16:9 aspect ratio and a file size under 2 MB. Our "YT Thumb" preset automatically crops your image to this ratio. Export as JPEG at quality 85–90% to stay comfortably within the 2 MB limit while maintaining sharp visual quality.
Does thumbnail image quality affect YouTube CTR?
Yes significantly. YouTube's own Creator Academy data shows thumbnails are the single biggest factor in click-through rate after video title. A sharp, correctly-sized thumbnail at 1280×720 avoids YouTube's automatic re-scaling artifacts, ensuring your thumbnail looks crisp on all device sizes.
