Why Thumbnails Matter

Thumbnails are the first thing people see when browsing content. A well-designed thumbnail can dramatically increase click-through rates for videos, blog posts, and product listings. Studies show that custom thumbnails can increase video views by up to 154%.

Ideal Thumbnail Sizes

• YouTube: 1280 x 720 px (16:9 ratio, minimum 640px wide)
• Blog featured images: 1200 x 628 px (standard Open Graph size)
• E-commerce products: 800 x 800 px (square, white background)

Design Tips

• Use bright, contrasting colors that stand out in feeds.
• Include human faces when possible; they draw attention.
• Add bold, readable text (3-5 words maximum).
• Keep the design clean and uncluttered.
• Test at small sizes to ensure legibility.
