Pinterest has become an essential visual search and discovery engine for brands and creators aiming to inspire and convert audiences. In 2025, crafting perfectly sized, eye-catching creatives isn’t just a best practice—it’s the expectation, especially for marketers who want to elevate their campaigns above the noise. As experts in multi-size, responsive ad generation at SizeIM, we’ve seen firsthand how a deep understanding of Pinterest ad sizes and design nuances can help agencies and designers maximize both their workflow efficiency and campaign results.
Why Pinterest Ad Size Mastery Matters More in 2025
As Pinterest evolves as a mobile-first platform—over 80% of users browse on their phones—consistent, properly sized visuals are fundamental to ad performance. Even the strongest idea can be undercut by cut-off product details, blurred typography, or mismatched duplications across carousels and boards. For agencies and designers managing multiple brands and projects, the ability to create high-quality, multi-format assets quickly both preserves workflow bandwidth and ensures visual consistency, reducing costly manual errors.

Design Tips to Boost Engagement in 2025
At SizeIM, we treat design as a balance between brand integrity, platform trends, and user psychology. Here’s how to make your Pinterest creatives stand out and connect:
1. Focus on Vertical Visual Storytelling
- Think mobile-first: 2:3 vertical (1000×1500) is the gold standard—uses more screen real estate, draws focus, and drives up engagement rates.
- Don’t waste space: Borders or horizontal formats get cropped or minimized on mobile, costing visibility and clicks.
2. Prioritize Consistent Brand Assets and Readable Text
- Brand kit is key: Use consistent logo placement, color palette, and fonts across all ad variants to build recognition and trust as your creative recirculates.
- Limit superimposed text: No more than 20% of the creative, always with strong contrast. Pin descriptions do the talking—let visuals do the selling.
- Keep headlines short and punchy: Let viewers grasp intent in one glance, even as they scroll quickly.
3. Make Your Calls-to-Action Crystal Clear
- Use concise CTAs like “Shop Now”, “Get Inspired”, or “See How” with a design that’s distinct from the background.
- Ensure the CTA is visible in mobile and desktop previews; avoid placing it at the very bottom where overlays may obscure it.
4. Optimize Carousel and Collection Ads for Storytelling
- Tell a logical story or showcase product features step-by-step. Users swipe through with intent when each frame adds value.
- Plan the sequence holistically: design assets as a set, not standalone images, so transitions feel natural.
- Stick to 3–5 images: Overcrowding carousels fragments the message and overwhelms scroll-fatigued users.
5. Video & Motion: Grab Attention Fast
- Lead with your most striking visual in the first 1–2 seconds.
- Subtle animation (even in static pins) draws the eye—think floating elements or a slight parallax background.
- Closed captions or graphic callouts ensure your message gets across silently; many users browse with sound off.
6. Prioritize Accessibility and Authenticity
- Test for strong color contrast—especially important on small screens in outdoor light.
- Choose diverse, real-world imagery over generic stock photos. Pinterest audiences value authenticity and inclusivity in brand visuals.
- Add descriptive alt text for Pins—boosts SEO and increases reach among visually impaired users.
Step-by-Step: Our Workflow for Pinterest Ads at Scale
Managing multi-format assets for diverse campaigns can be daunting if you’re doing everything manually. Here’s our approach to combining efficiency with flawless output:
- Start with a single master creative in the best vertical ratio (2:3). Build out your design fully before creating variants.
- Leverage responsive resizing tools. Rather than duplicating and editing each asset size by hand, use a solution like SizeIM to generate every required ad format. This ensures your core elements remain harmonized across the whole ad set.
- Centralize your brand assets. Keep logos, color schemes, and font files in a shared brand kit so every ad stays consistent, regardless of who on your team handles adjustments or approvals.
- Optimize and compress images before upload. Slow-loading assets lose visibility. Even small savings in file size can result in better placement and user experience without sacrificing quality.
- Preview your ads in context. Use Pinterest’s preview tools or download test mockups to see how your creative displays in-feed, on mobile, and on boards. Adjust as needed for cropping, clarity, and composition.
- Deploy, monitor, and iterate. Review performance analytics on engagement and conversions, and refine subsequent creatives based on audience response.
Common Pitfalls—and Proven Fixes
- Horizontal pins and videos: They see less engagement—always prioritize vertical, unless context clearly benefits horizontal layouts.
- Poor file optimization: Avoid pixelated assets or non-standard ratios (e.g., landscape images uploaded to a vertical feed).
- Copy or logo too close to the edges: Pinterest may auto-crop for display variants; build in extra margin for crucial information.
- Overcomplicated layouts: Visual overload reduces the impact—simplicity and clarity most often win in crowded feeds.
