Thumbnail templates and brand kits for a growing creator portfolio

A YouTube growth agency needed scroll-stopping thumbnails and cohesive channel branding for every creator it signed. We built the design kits behind them.

The finished work belongs to our agency partner and their clients, so we don't publish it. This page explains what we did instead.

The brief

What the agency needed

Thumbnails were made in a rush and rarely tested, and each channel looked different from video to video. The agency needed a repeatable way to design, test and improve thumbnails at scale.

What HBTN did

How we delivered it

  1. 01

    Built a brand kit per channel

    Logos, colour palettes, typography, banners and end screens so every channel looked cohesive and recognisable.

    Designed thumbnail templates

    Flexible layouts for faces, text and objects that stay legible at every size, from TV to mobile.

  3. 03

    Supported testing

    Three thumbnail variants per video, so the agency could A/B test and keep the best performer.

  4. 04

    Learned from the data

    We reviewed click-through results with the agency and fed the winning patterns back into the templates.
