> Quick answer: Feed ads need at least 1080 pixels wide. Stories and Reels need 1440x2560. If your image falls short, AI Upscale in Coinis Revise enlarges it cleanly without visible pixelation.
Low-resolution assets get compressed and stretched on mobile. That costs you clicks. Here's how to fix it fast.
Why Instagram Ad Resolution Matters
Sharp images convert. Pixelated ones get scrolled past.
Recommended Instagram ad dimensions
Instagram displays feed ads at up to 1080 pixels wide. Portrait format targets 1080x1440. Stories and Reels fill a full 9:16 screen at 1440x2560. Hitting those targets keeps your ads crisp on every device, from budget Androids to the latest iPhones.
What happens when images are too small
Per Instagram's Help Center, photos shared at low resolution get stretched, sometimes down to a display width of just 320 pixels. On modern high-density screens, that looks noticeably blurry. Blurry ads lose attention before a single word gets read.
When you need to upscale
Upscaling becomes necessary when your source file is under 1080 pixels wide for feed ads, or under 1440 pixels wide for Stories. That happens often with product photos from suppliers, old creative files, or content repurposed from organic social posts.
Instagram Ad Image Size Requirements by Format
Every format has a recommended target size and a hard minimum. Staying above both keeps your ads sharp across placements.
Feed image ads (1080x1080 or 1080x1440)
Square feed ads work best at 1080x1080. Portrait feed ads target 1080x1440. Meta accepts a minimum of 600x600 for square ads, but anything that small looks pixelated on most phones and is not recommended.
Stories ads (1440x2560)
Stories fill the full screen vertically at a 9.16 ratio. The recommended resolution is 1440x2560. Images smaller than that get stretched to fill the frame, and sharpness drops fast.
Reels ads (1440x2560)
Reels use the same 9.16 format as Stories. Same 1440x2560 recommendation. Because Reels compete directly with organic creator content, visual quality matters even more than in feed placements.
Minimum resolution floors (600+ pixels)
Per Meta's Ads documentation, the minimum accepted dimension for square feed ads is 600x600 pixels. Drop below that and Instagram may resize the image automatically, typically with visible quality loss. A 30MB file size limit applies to all formats.
How to Upscale an Instagram Ad Image
Four steps take you from a low-res file to a clean, upload-ready image.
Step 1: Check your current image resolution
Open your file in any image viewer or photo editor. Check the pixel dimensions listed in the file info. If the width is below 1080 pixels for feed, or below 1440 pixels for Stories and Reels, upscale before uploading to Meta Ads Manager.
Step 2: Use Revise AI Upscale to enlarge without quality loss
Open Coinis Revise. Upload your image. Select AI Upscale. The feature uses cutting-edge AI models to analyze your image and add realistic detail during enlargement. That process is fundamentally different from traditional pixel-stretching. Traditional resizing just spreads existing pixels over a larger canvas, making edges soft and blocky. AI Upscale reconstructs the detail instead. The result is a sharper image at the larger size.
Step 3: Verify the new dimensions match your target format
After upscaling, confirm the output dimensions. Feed ads need 1080 pixels wide at minimum. Stories and Reels need 1440x2560. If the proportions are off for your target placement, use Smart Resize in Revise to reframe the image without distortion.
Step 4: Export and prepare for upload
Export as JPEG or PNG. Keep the file under 30MB. Upload to Meta Ads Manager. Note that Instagram compresses images above 1080 pixels wide for feed, so targeting 1080-1440px hits the sweet spot without triggering unnecessary over-compression.
Alternative. Generate New Ad Images at Full Resolution
Sometimes starting fresh beats fixing a bad source file.
Why starting with Image Ads is sometimes better
AI Upscale can only do so much when the original image is very low quality. A badly blurred product photo will still look soft after enhancement. If the source file is beyond recovery, generating a new creative gives you full control from the start.
How Image Ads generates at recommended dimensions
Coinis Image Ads generates ad creatives directly from your product URL at ad-ready dimensions. Square, portrait, Stories. No upscaling required. The output is sharp at full resolution by default, ready to upload without any extra editing steps.
Best Practices for Ad Image Quality
Start with the highest-resolution source possible
Better input produces better output. A 1200-pixel source enlarged to 1440 looks far cleaner than a 400-pixel source pushed to the same target. When sourcing product images, always request the largest available file from your supplier or photographer.
Test upscaled images on mobile before launching
Preview every upscaled ad on an actual phone before publishing. Desktop previews hide compression artifacts and sharpness issues that are obvious on mobile screens, where your audience actually sees the ad.
Consider refresh cycles for creative fatigue
Even a perfectly sharp image loses performance over time. Use Variate in Revise to generate fresh versions of your best creative instead of running the same asset on a loop indefinitely.

Frequently Asked Questions
What is the minimum resolution for an Instagram ad image?
Meta accepts a minimum of 600x600 pixels for square feed ads and 600x315 for landscape. However, any image below 1080 pixels wide will appear blurry on most modern mobile screens. Always target 1080 pixels wide or higher for feed, and 1440x2560 for Stories and Reels.
Does AI upscaling really improve quality, or just make the file bigger?
Traditional resizing stretches existing pixels and softens detail. AI upscaling analyzes the image and reconstructs realistic detail at the larger size. The result is meaningfully sharper than standard resizing, though a very low-quality source image will still have limits.
