Before & after
Same prompt, same agent — the only difference is the skill.
Creating a cohesive visual style for your YouTube channel is really important for building recognition and professionalism. That's a great goal. To design something that fits your brand and appeals to your audience, I'd need to know more about your channel. What's your niche — educational, entertainment, gaming, business, lifestyle? Who are your typical viewers? Do you already have a brand color palette or logo? What's the tone you want — modern and minimal, warm and friendly, edgy and bold, corporate? Also, do you have any design tools or constraints I should know about — are you using templates, or do you have someone who can design custom assets? And how much time do you want to spend creating these assets per video? Once I understand your brand direction, I can outline visual conventions for banners, avatars, and thumbnails. Do you have examples of channels you admire visually?

Your banner text gets chopped off on phones, your profile picture is a smudge next to comments, and every thumbnail looks like it came from a different channel. This skill specifies each asset at the size viewers actually see it, with pixel coordinates, so a freelancer can match your look on the first try.
What it does
- Designs the avatar for the 24-48 px circle shown beside titles and comments, not the 800 px upload
- Places banner text inside the 1546 x 423 area every device shows, with exact coordinates on the 2560 x 1440 canvas
- Builds a zoned 1280 x 720 thumbnail template with keep-clear areas for the timestamp, progress bar, and hover icons
- Locks one signature element and one variable per series, so a playlist reads as a set without every video looking the same
- Gives editors written rules naming which elements they may change and which stay locked
- Catches common mistakes before upload: under-minimum banners, wordmark avatars, text under the timestamp, and fonts licensed for personal use only
What you get
A spec sheet with exact export sizes. Avatar and banner layout plans. A thumbnail zone table in pixels, with series variants. A pre-upload checklist that includes small-size tests.
Best for
New YouTubers setting up a channel, creators rebranding, and editors or VAs who build thumbnails for someone else and need rules they can follow without guessing.
