Turning four master designs into hundreds of finished DOOH assets
Hostplus campaigns can require hundreds of different DOOH specifications across Australia.
Each format has its own dimensions, proportions and layout considerations. Building them one by one means hours of resizing, adjusting and checking the same creative.
So I built a Figma workflow to automate the rollout.
Create the masters. Paste in the specs. Generate the campaign.
The challenge:
A single rollout can contain more than 100 individual media specifications. At around 15 minutes per asset:
A 100 spec rollout = 25 hours
of production spent largely on resizing and layout adjustments.
The challenge is not just volume either.
Hostplus artwork follows specific rules around proportions, margins, logo placement and brand elements. Different aspect ratios require different treatments. Every ratio has different brand guidelines applications, each with its own layout behaviour.
We needed speed without losing that control.
The system
Four designs in. Hundreds of assets out.
The workflow starts with four master creative formats.
From there, the production process comes down to two core actions.
01 Generate every required size
02 Apply the correct Hostplus rules
The Figma tooling handles the repetitive work in between.
01. Generate the rollout
Paste the spec sheet. Build every size.
The DOOH Rollout tool takes the dimensions supplied in the media spec sheet and creates the required Figma frames automatically.
Whether the booking contains 20 sizes or 200, the same process applies.
It can generate the required frames, scale creative into different aspect ratios and prepare the rollout without a designer manually building every format.
One set of master designs becomes the full media booking.
02. Snap everything to brand
One action applies the Hostplus rules
Generating the sizes is only half the problem.
Each asset still needs to behave correctly for its proportions.
The second tool identifies the appropriate Hostplus format and applies the relevant rules for margins, logo spacing and brand elements.
The underlying system accounts for rules such as calculated margins, logo clear space and different layout behaviour across changing aspect ratios.
So instead of a designer calculating and correcting every asset individually, the system does it across the rollout.
Generate the sizes. Apply the rules. Review the exceptions.
Changes at scale
One change can update the whole rollout
Large campaigns rarely stay untouched.
Copy changes. Logos change. Creative gets refined.
The Figma files were built with shared components and smart controls so changes can be made across the rollout without reopening hundreds of individual assets.
Update the master.
Push the change through the system.
Review the result.
This turns client amends from another round of repetitive production into a controlled bulk update.
1 hour of design. 100 assets ready to roll.
The value of the system is simple.
We spend around 1 hour creating the master creative.
From there, the plugin can generate 100 different DOOH specifications in seconds.
Without automation, producing those 100 assets at 15 minutes each would add another 25 hours of production.
The impact
1 hour
creating the master creative
100+
generated from those masters
25 hours
of manual rollout removed
96% less production time on a 100 asset rollout.
As the number of specs increases, the time saved scales with it.
Create once. Roll out at scale.
