You know what is a YouTube thumbnail — we’re not here to waste your time.

We’ll teach you how to make the perfect thumbnail.

How to Make a Good YouTube Thumbnail

An effective YouTube thumbnail is essentially a mini-billboard that needs to grab attention. It should raise curiosity, and accurately represent your content.

1. Follow the size guidelines

Recommended size for YouTube Thumbnails is 1280x720

Thumbnails might look small in search results, but they can show up bigger in other places, like when someone embeds a video on a website.

Sizing tips:

  • Width: At least 640 pixels.
  • Ideal Size: 1280 x 720 pixels (That’s the best size for YouTube).
  • Aspect Ratio: Stick to 16:9; it’s what YouTube likes best, especially for regular videos (not Shorts).

Quality tips:

  • Quality: Start with a big picture. You can always make it smaller without losing quality.
  • File Types: Use JPG, PNG, GIF, or BMP to keep the quality good.
  • File Size: Keep it under 2MB. That’s YouTube’s max limit.

2. Background

For the background, you’ve got 2 main options:

  1. Easy Thumbnail Option: Use a still from your video. YouTube may suggest stills, but they might not be the most engaging, so you’ll need to add a custom thumbnail.
  2. Enhance for Impact: Consider editing a chosen still with photo editing software to improve its appeal. Highly recommended!

Use images that relate directly to your video’s content, like your reaction.

If using your own image with a face: Make sure your aren’t closed — unless it’s not part of the show.

3. Text is mandatory

Very few thumbnails make it big without having any text — you generally need to have a big audience to have guaranteed success.

Add text, but don’t overdo it. Leave the detailed description to your video’s title.

Here’s why you should do this:

  • Clarity: Text can immediately tell viewers what your video is about, especially if the image is ambiguous. This can be especially helpful for educational or instructional videos.
  • Click-through rate (CTR): Well-written and designed text can grab attention and entice viewers to click on your thumbnail, potentially increasing your YouTube CTR.
  • Accessibility: Viewers who are deaf or hard of hearing may rely on the text in your thumbnail to understand the video’s content.

4. Personal Brand

When someone scrolls through YouTube, your video thumbnails instantly jump out. That’s the power of a strong brand identity on YouTube!

Why Your Brand Matters:

  • Attract viewers: A clear brand image tells people what you’re about, drawing in your target audience.
  • Build trust: Consistency across your channel (colors, fonts, visuals) makes you look professional and reliable.
  • Grow your community: Strong branding makes your channel memorable, turning viewers into loyal fans.

Get Going:

  • Think visually: Choose imagery that represents your content and attracts your ideal audience.
  • Pick your colors: A consistent color palette helps viewers recognize your brand instantly.
  • Font matters: Choose fonts that are clear, readable, and match your personality.

Remember: Branding is a journey, not a destination.

  • Theme: Pick a style that reflects your channel’s vibe and stick with it. Think vibrant and playful for fun content, or sleek and minimalist for a serious tone.
  • Color Coordination: Establish a color palette that screams “you” and use it across all your thumbnails. Consistency is key to building recognition.
  • Font: Choose a font that’s readable, matches your theme, and makes a statement. Don’t be afraid to get creative!
  • Logo: Add your logo subtly on each thumbnail for maximum brand awareness. Think corner placement, not bottom right (video time will hide it).
