Multi-size ad production is a core challenge for digital agencies juggling huge campaign rosters, tight client deadlines, and the ever-growing list of publishing specs from ad networks and social channels. It’s a process that can be both a creative bottleneck and a silent killer of profit margins. We’ve lived this firsthand, which is exactly why we built our agency workflows around efficiency, clarity, and the best technologies on offer. Here are five advanced, actionable techniques—rooted in our real-world experience—that can truly streamline multi-size ad production for digital agencies.
1. Establish a Responsive-First Ad Design Framework
Start by abandoning the idea of static dimensions as your creative starting point. Instead, embrace the logic of responsive web design—think of each ad as a flexible composition rather than a rigid rectangle. At SizeIM, we promote designing master creatives in a responsive canvas, enabling instant reshaping for any required ad spec without losing quality or layout integrity.
- Single Master Creative: Build out one flexible design and use it as your source of truth for all ad shapes and sizes.
- Responsive Containers: Employ a grid system and adaptable spacing so elements intelligently reflow.
- Preview Early, Preview Often: Use live previews and automated outputs to assess each variation as you tweak.
When your workflow begins with responsiveness in mind, you sidestep the tedious back-and-forth of reworking every ad individually—a method that saves hours on every campaign cycle.
2. Centralize Brand Assets and Templates for True Consistency
Brand consistency isn’t just about the logo. It’s the tone, the palette, the microcopy, the icons, and the punchy calls-to-action. We’ve found that agencies operate at a higher level when they centralize every asset and template in one place, giving everyone—from designers to account managers—single-click access to proper versions.
- Asset Libraries: Leverage a brand kit manager to control colors, fonts, logos, and imagery across all ad sizes and projects.
- Role-Based Access: Assign access and edit rights by role, reducing errors and accidental off-brand edits.
- Reusable Templates: Curate approved templates that can be duplicated and fine-tuned for new campaigns—no need to reinvent each time.
This not only upholds visual identity, it allows your team to collaborate smoothly and dramatically cut time spent hunting for the right logo or font file.
3. Embrace Automation—Especially Automated Resizing
The biggest leap in agency efficiency comes from automation that works without complex onboarding or steep learning curves. Automated resizing, when done right, changes everything. SizeIM’s engine lets you design once and export in as many formats and networks as your campaign demands—Google, Facebook, programmatic, and beyond—no manual resizing required.
- Instant Multi-Export: Generate dozens of ad dimensions (Leaderboard, Billboard, Inline Rectangle, etc.) in seconds, rather than days.
- Error Reduction: Shrink the margin for human reflow mistakes by leaving mechanical chores to the algorithm.
- Focus on Fine-Tuning: Spend your valuable time perfecting messaging and creative for each channel, not pixel pushing.
For those with high-volume campaigns or multiple clients, this is a game-changer. You can explore how we automate multi-size ad creation here.
4. Streamline Approvals, Collaboration, and Versioning
Any digital agency knows the cost of delays: every new feedback loop, email thread, or lost file introduces friction in multi-size ad production. We recommend integrating streamlined collaboration and version-control systems as part of your production stack.
- In-App Commenting: Enable clients and team members to annotate and approve directly on live ad previews across all sizes.
- Automated Version Histories: Every change—no matter how small—is logged, so you can quickly revert or reference previous states.
- Batch Approvals: Present all ad sizes for approval in unified dashboards to reduce decision fatigue and overlooked assets.
With centralized feedback, you eliminate endless email chains, boost transparency, and get final sign-off on ad sets faster—critical for time-sensitive campaigns.
5. Build an Agile Optimization and Iteration Loop
Every campaign is an opportunity for learning, and multi-size ad production offers vast data to optimize future projects. The trick is to systematize iteration without bogging down your pipeline:
- Run Controlled A/B/C Tests: Systematically vary creative, CTA, or imagery across sizes to see what works on which platform.
- Centralize Performance Metrics: Pull engagement data for each creative and size back into your asset management system for rapid reporting.
- Develop Iterative Templates: Constantly update your template library to reflect new learnings and high-performing patterns, making each future campaign more efficient.
Over time, this builds a virtuous cycle: rapid deployment, fast feedback, and informed creative decisions—so your best work keeps getting even better.
Bonus: Agency-Specific Tips from Our Experience
- Project Scoping: Nail down required sizes for all networks in the briefing phase. Ambiguity here is the enemy of efficiency!
- Client Onboarding: Walk new clients through your streamlined process up front. Set clear expectations about the power (and limits) of automation—this builds trust and cuts down on scope creep.
- Training and Support: Empower every member of your team (not just designers!) to use your asset library and responsive workflows, so you’re never single-threaded.
