- Mauricio Martinez
Every week, advertisers waste hours hunting for updated creative specs across multiple platforms. You’re briefing a designer for a Facebook campaign. You need Instagram Story dimensions. Your client asks about LinkedIn specs. You end up with seven browser tabs open, outdated blog posts, and conflicting information.
This guide solves that. Here are accurate, simplified, and up-to-date dimensions for the most common ad formats across Meta, LinkedIn, and Google Ads. Bookmark this page and use it to brief designers, optimize campaigns, or share with clients and team members.
Meta Ads: Facebook & Instagram
According to Meta’s official 2026 ad specifications, Feed Images use 1080 × 1080 px (1:1) as standard square format working across both platforms. Industry analysis shows 1440 × 1800 px (4:5) is recommended for more screen real estate, with Meta’s data showing 4:5 images typically outperform 1:1 for mobile engagement.
Stories & Reels require 1080 × 1920 px (9:16) full-screen vertical format. Keep critical text and logos in the center 1080 × 1350 px area to avoid overlap with interface elements.
LinkedIn Single Image Ads
According to LinkedIn’s official ad specifications, Horizontal format uses 1200 × 628 px (1.91:1) as LinkedIn’s standard landscape, matching Facebook link posts for easy repurposing.
LinkedIn recommends Square at 1200 × 1200 px (1:1) for delivery across both desktop and mobile, working well for mobile-first campaigns.
Vertical formats are accepted at 628 × 1200 px (1:1.91), 600 × 900 px (2:3), and 720 × 900 px (4:5), but deliver only to mobile. Stick with square or landscape as vertical formats rarely justify extra production complexity.
Google Responsive Display Ads
Landscape (1.91:1): Recommended 1200 × 628 px, minimum 600 × 314 px. Use recommended size. Google compresses aggressively.
Square (1:1): Recommended 1200 × 1200 px, minimum 300 × 300 px. Always upload square assets alongside landscape.
Portrait: 960 × 1200 px or 1200 × 1500 px. Optional but recommended for mobile-heavy placements.
How to Use This Guide
Design High-Resolution: Use recommended resolutions, not minimums. Platforms compress images during upload. Starting with higher resolution ensures ads stay sharp across devices.
Maintain Aspect Ratios: Platforms auto-crop images that don’t match required ratios. Design for the aspect ratio, not just pixel dimensions.
Design for Safe Zones: Keep critical text, faces, products, and CTAs in center safe zones. For Stories, that’s the center 1080 × 1350 px area. For Feed, avoid the bottom 150 pixels.
Platform Tips: Meta – upload both 1:1 and 4:5 versions. LinkedIn – stick with landscape or square. Google RDAs – upload at least 5 images per aspect ratio for better machine learning performance.
