The Ultimate LinkedIn Post Size Guide for 2024: Boost Your Reach

A single‑image post appears in the main feed and uses a 1.91:1 aspect ratio. The recommended canvas is 1200 × 627 pixels, which ensures the picture looks sharp on both desktop and mobile. Keep important text or branding at least 150 pixels away from the edges to avoid cropping. Export as PNG for graphics or JPEG for photos, and you’ll see a clean, professional look without pixelation.

Square posts are ideal for infographics or product showcases because they occupy more vertical space in the feed. Use a 1080 × 1080 pixel canvas, which aligns with Instagram’s standard and retains clarity across devices. Avoid placing key elements too close to the corners; a 100‑pixel safe zone works well. When you need a quick, on‑brand visual, DesignLumo can turn a text prompt into a ready‑to‑use square design.

While text‑only posts don’t have an image size, using line breaks and bullet points can improve readability. Aim for 1‑2 short paragraphs, a maximum of 150 characters per line, and include a relevant hashtag at the end. Pairing the post with a subtle background color (use the platform’s native color picker) can make it stand out without breaking any size rules. This approach works well for thought‑leadership updates.

Carousel cards use a square format, each 1080 × 1080 pixels, and can contain up to nine images. Consistency across cards is crucial; keep fonts, colors, and margins identical to create a seamless flow. When designing a multi‑step tutorial, place the next‑step indicator on the right side of each card. DesignLumo’s LinkedIn carousel maker automates this process, letting you generate all cards from a single prompt.

Document carousels display PDFs as scrollable pages, each rendered at 850 × 1100 pixels. This taller aspect ratio lets you fit more text without sacrificing readability. Use clear headings, ample white space, and a consistent footer on every page. Export the file as a PDF and upload directly to LinkedIn; the platform will slice it into swipeable cards. A well‑crafted document carousel can generate leads by offering downloadable resources.

When adding videos to a carousel, each slide needs a thumbnail image that matches the square card size of 1080 × 1080 pixels. Choose a frame that captures the video's core message and overlay a play icon for clarity. Keep the thumbnail file under 5 MB to ensure quick loading. Pair the thumbnail with a concise caption to boost engagement on both desktop and mobile feeds.

Sponsored content follows the same dimensions as organic single‑image posts: 1200 × 627 pixels. However, ads benefit from a stronger visual hierarchy—place the brand logo in the top‑left corner and a call‑to‑action button near the bottom. Use high‑contrast colors to capture attention within the first few seconds of scrolling. Testing multiple variations in DesignLumo can help you identify the highest‑performing creative.

Stories occupy the full vertical space on mobile, so a portrait canvas of 1080 × 1920 pixels is required. Keep text under 20% of the frame to avoid covering the main visual. Use a safe zone of 250 pixels at the top and bottom for platform UI elements. Adding subtle motion graphics can enhance retention, and DesignLumo can generate layered story templates that you edit in seconds.

Event pages display a wide banner at the top of the page. The optimal size is 1584 × 396 pixels, which preserves clarity on high‑resolution screens. Align the event title and date in the central 60% of the canvas, leaving enough margin for the platform’s overlay buttons. A clean, professional cover can increase RSVP rates, especially when paired with a compelling tagline generated by DesignLumo.
