Choosing a slide size before you design helps keep text, images and page edges consistent. These pixel dimensions use a 1080-pixel width as a practical design target. Instagram and publishing tools may change their requirements, so check the current options in the destination app before posting.

Which carousel format should you choose?
Square (1:1)
Square slides are useful for compact diagrams, simple lists and layouts designed around a balanced canvas. They are also a straightforward choice when your source pages are close to square or you want a consistent tile shape.
Portrait (4:5)
Portrait slides use more vertical room in a feed. They can suit PDF pages with headings, short paragraphs and diagrams arranged from top to bottom. The GYROX PDF carousel converter offers this 4:5 portrait option.
Portrait (3:4)
Some workflows offer a taller portrait canvas. The Carousel Quality Checker can compare images against 3:4 dimensions, but the PDF Carousel and Instagram Carousel Splitter tools currently export 1:1 or 4:5 only. Use a tool that explicitly supports 3:4 if you need that exact output.
Landscape (1.91:1)
Landscape gives a wide, short canvas that can suit photographs, horizontal diagrams or a design made for that shape. The GYROX Carousel Quality Checker can check 1080 × 566 landscape slides; the PDF carousel converter does not create this format.
Keep the same ratio throughout a carousel
Prepare every slide at the same dimensions so the sequence looks deliberate and content does not shift between frames. Mixing ratios can lead to inconsistent margins, resized previews or cropping by a publishing workflow. Check the first and last slide as carefully as the middle slides.
Keep text and faces away from the edges
Leave comfortable margins around titles, captions, faces and important diagrams. A platform preview, profile grid or app interface may crop or cover areas differently. Do not place essential details directly against the edge; review the final slide in the destination app.
Use a sharp source and check phone readability
Start from a high-resolution source that matches the target ratio. Upscaling a small image does not restore detail. For PDF pages, portrait 4:5 can provide more vertical space than square, but it cannot enlarge tiny type or redesign a dense page. Simplify the PDF source if the text is hard to read on a phone.
Check a finished carousel
Upload 2–20 slide images to the Carousel Quality Checker to review dimensions, aspect ratios and consistency. To create the slides from a document, use PDF to Instagram Carousel. For a panoramic image, use the Instagram Carousel Splitter, or build text slides in the Social Media Carousel Maker.
