What makes a Fortnite thumbnail work
Fortnite videos compete in one of the busiest corners of YouTube. The thumbnails that stand out do three things: they show one moment, they read in a second, and they use a colour language players already know from the game.
Many viewers see your thumbnail small: on a phone, in the sidebar next to another video, or on a TV across the room. Fine detail disappears at that size. Shapes, faces and colour survive. Every rule on this page follows from that.
Use the colours players already know
Fortnite has taught its players to read colour. Grey, green, blue, purple and gold tell them how rare an item is, so a gold glow already means "big reward" and purple means "high stakes". Use one of these as the accent of your thumbnail and keep the rest of the frame calm. Red stays free for mistakes, arrows and circles.
One character, one emotion
The character does the emotional work. Make it large (cut at the chest or the waist), give it one exaggerated expression and point its eyes at the thing that matters: the text, the loot or the opponent. The examples above are generated with Base.Tube and use the game's own skins and places. On your own channel, your skin in your own gameplay works, and so does a photo of you making the same big expression next to the game.
Text: fewer words, thicker outlines
Three words is the upper limit. Use capitals, a heavy condensed font and a thick black outline so the text survives any background. The words should add something the image cannot say on its own, like "1 HP" or "PICKAXE ONLY", instead of repeating the video title. To compare heavy display fonts side by side, see the YouTube thumbnail fonts guide.
Five layouts, one per video type
Most Fortnite videos fit one of five shapes: victory, progression, live event, face cam or challenge. The layout recipes above give the structure of each one. Pick the layout that matches the promise of your video, then change the character, the colour and the words. Keeping the same layout across a series also helps returning viewers spot your videos.
Backgrounds that do not fight the subject
A Fortnite thumbnail background sets the mood and nothing else. A bright island and blue sky say "fun" and suit wins and updates. A dark purple storm says "tension" and suits montages. Whatever you choose, blur it or darken it so it never competes with the character or the text. For more ways to build a background that stays behind the subject, see the YouTube thumbnail backgrounds guide.
Size and format
Upload thumbnails at 1280 × 720 pixels, in a 16:9 frame. For the current file size and format limits, see the YouTube thumbnail size guide. Keep important details away from the bottom-right corner, where YouTube shows the video length.
Check it before you upload
A thumbnail that looks great full-screen can fall apart at feed size. Put yours next to other videos in the YouTube thumbnail preview and compare versions with the thumbnail tester. No tool can predict how many people will click before a video is live: the real test is how the thumbnail performs on YouTube. When you connect your channel, Base.Tube shows the real impressions and click-through rate of each video.
