Instagram Carousel Resizer

Carousel posts get higher engagement than single images because users swipe through multiple slides. Each interaction signals interest to the algorithm. All slides must use the same dimensions, either 1080x1080 square or 1080x1350 portrait. Mix dimensions and Instagram forces everything to match the first slide, cropping the rest unpredictably.

Carousels Outperform Single Images

Data shows carousel posts consistently get higher engagement than single images. Every swipe counts as interaction, signaling to Instagram that your content is worth showing to more people. The more slides users view, the better your post performs. Use all 10 slides when you have the content to fill them.

Keep Dimensions Consistent

Your first slide determines the aspect ratio for the entire carousel. Upload a square image first and all following slides get cropped to square. Upload portrait first and everything becomes portrait. Plan your carousel dimensions before you start. Mixing aspect ratios creates awkward crops and ruins the visual flow.

Tell Stories Across Slides

Carousels excel at tutorials, before-and-afters, product showcases, and educational content. Each slide builds on the last, keeping viewers engaged through the entire sequence. End with a call to action on your final slide. The swipe-through format naturally leads users toward taking action.

Instagram Square Post

1080 x 1080

Square posts get cropped when dimensions are wrong. Instagram's algorithm favors properly sized images, so 1080x1080 pixels gives you the best quality and reach. No compression, no cropping, just clean visuals that look sharp on every device.

Instagram Portrait Post

1080 x 1350

Portrait posts take up more screen space in the feed, which means more visibility and better engagement. The 4:5 aspect ratio at 1080x1350 pixels is Instagram's preferred vertical format. Your photos display larger than square posts without getting cropped.

Instagram Story

1080 x 1920

Stories fill the entire phone screen at 1080x1920 pixels with a 9:16 aspect ratio. Wrong dimensions leave ugly black bars or crop important content. Get edge-to-edge coverage that looks intentional and professional.

Instagram Reel

1080 x 1920

Reels are Instagram's fastest-growing format for reach and discovery. At 1080x1920 pixels with a 9:16 aspect ratio, your vertical video fills the entire screen in the Reels tab. Wrong dimensions mean your content gets cropped or letterboxed, killing that full-screen impact.

Instagram Profile Picture

400 x 400

Your profile picture displays at just 110x110 pixels on mobile, but Instagram stores it at 320x320. Upload at least 400x400 pixels for a crisp, clear image that doesn't look pixelated when people tap to expand it. First impressions happen in that tiny circle.
