Many law firms in 2026 are still only posting single images or text updates on LinkedIn and wonder why engagement remains stubbornly low. Meanwhile, a handful of practices are generating thousands of impressions and meaningful conversations using a format many solicitors don’t even know exists: LinkedIn carousels.

If you’ve never created a carousel post, or if you’ve seen them in your feed but assumed they require design skills or expensive software, this guide explains exactly what they are, why they massively outperform other content types, and how to create them for your law firm without technical expertise.

The data is compelling enough that ignoring carousels means leaving significant visibility and engagement on the table.

What Is a LinkedIn Carousel Post?

A LinkedIn carousel is a post containing multiple slides, often with a mix of visuals and text that users swipe through directly in their feed.

They work particularly well when you have content that doesn’t fit in a single image: step-by-step guides, data breakdowns, tips lists, case studies, educational content, or any narrative that benefits from a slide-by-slide structure.

For law firms, this format is ideal for explaining legal processes (the conveyancing journey in 8 slides), breaking down recent legal changes (what the new employment law amendments mean for employers), sharing case study outcomes with proper consent (how we helped a client resolve a complex commercial dispute), or providing educational content that positions your knowledge (5 things to check before signing an employment contract).

The format naturally suits the way solicitors communicate, by breaking complex information into digestible, sequential pieces that build understanding progressively rather than overwhelming readers with everything at once.

LinkedIn Carousel Technical Specifications

Before creating your carousel, understanding the technical requirements prevents formatting issues and ensures your content displays correctly across desktop and mobile:

Recommended slide size: 1080 x 1080 pixels (square) or 1920 x 1080 pixels (landscape)

Aspect ratio: 1:1 (square) works best for most feeds; 16:9 for landscape orientation

Accepted file formats: PDF, PPT, PPTX, DOC, DOCX

Maximum file size: 100MB

Maximum number of slides: Up to 300 per document (technical limit), though best practice suggests keeping carousels under 10-15 slides for optimal engagement

Minimum number of slides: 2

The square format (1080 x 1080 pixels) is generally recommended because it takes up more screen space in the feed and performs better on both desktop and mobile devices. Keep text large enough to read without zooming (a minimum 24-point font is a good baseline), and leave enough margin around the edges so nothing gets clipped when LinkedIn processes your upload.

For law firms creating carousels, the square format ensures your content is equally readable whether potential clients are viewing on a desktop whilst at work or scrolling on a mobile during their commute.

How to Post a Carousel on LinkedIn

You don’t need any special account settings or permissions to post carousels. Both personal profiles and company pages can publish this content using the same process:

Step 1: Log in to your LinkedIn profile or company page

Step 2: Click “Start a post” as you would for any update

Step 3: Click “More” (the three dots or plus icon depending on your view)

Step 4: Select “Add a document”

Step 5: Upload your file from your computer, Dropbox, or Google Drive

Step 6: Add a title for the document (this appears above the carousel in the feed and acts as your headline)

Step 7: Write your caption, add relevant hashtags, and review the preview to ensure everything displays correctly

Step 8: Click “Post” to publish immediately or schedule for later

Critical detail: Only PDF, PPT, PPTX, DOC, and DOCX formats are accepted. All slides must be in a single file before uploading. You cannot add individual images the way you would on Instagram; everything must be compiled into a single document first.

For law firms, this workflow fits naturally into content creation processes. Create your carousel in PowerPoint (which most firms already use for client presentations), export it as a PDF, and upload it to LinkedIn. The barrier to entry is significantly lower than many solicitors assume.

What Makes LinkedIn Carousels Actually Perform for Law Firms

Knowing how to post a carousel technically is only half the challenge.

Hook People From Slide 1

Your first slide is your headline. If it doesn’t give a clear, specific promise, a surprising fact, a bold claim, or a provocative question, people won’t swipe to the second slide. Treat it like the subject line of an email.

Weak first slides for law firms:

• “Employment Law Update”
• “Understanding Conveyancing”
• “Family Law Tips”

Strong first slides for law firms:

• “The employment law change in April that 60% of employers are getting wrong”
• “The conveyancing search that buyers skip (and later regret)”
• “5 divorce myths that cost clients thousands in unnecessary legal fees”

The specific, outcome-focused hook tells potential clients exactly what value they’ll get by swiping through, creating immediate curiosity about the content.

Give Every Slide a Purpose

Each slide should either deliver value or spark enough curiosity to pull the reader to the next one. If a slide doesn’t do either, it weakens the carousel and increases the chance someone stops swiping.

For law firms, this means each slide in an educational carousel should either explain one specific aspect of a legal process, correct one common misconception, provide one actionable insight, or pose one thought-provoking question that the next slide answers.

Avoid slides that just say “let’s discuss” or “more information coming” without adding value. These transition slides feel like filler and train readers to stop swiping because they’re not consistently rewarded with useful information.

Keep the Design Clean and Readable

Minimal text, readable font sizes, sufficient white space. A carousel that looks cluttered on mobile will lose readers on slide 2, regardless of how valuable the content is.

For law firms, resist the temptation to cram every legal detail onto each slide. Remember that many potential clients will view your carousel on mobile during their commute or lunch break, and if they need to zoom in to read your text, you’ve lost them.

Practical guidelines:

• Maximum 15-20 words per slide for primary content
• Minimum 24-point font size
• High contrast between text and background (dark text on light background or vice versa)
• Consistent visual style across all slides so the carousel feels cohesive

End With a Clear Call to Action

Your last slide should tell the reader what to do next. Don’t let the momentum of a good carousel go to waste with a blank final slide or generic “follow us for more” message.

For law firms, effective final slide CTAs include:

• “Have you experienced this workplace issue? Share your experience in the comments”
• “Save this post to reference when you need conveyancing help”
• “What questions do you have about divorce settlements? Ask below”
• “Need advice on a commercial lease? Visit [your website] or call [your number]”
• “Follow us for weekly employment law insights you can actually use”

The data confirms this matters: posts that include a question get 77% more comments, and posts with a CTA to comment get 80% more engagement. If your last slide asks a direct question, you’re combining two of the platform’s highest-performing signals.

Scheduling LinkedIn Carousels in Advance

Creating carousels requires more effort than text posts or single images. Planning and scheduling them in advance ensures you maintain consistency without the pressure of creating carousel content at the last minute when you’re busy with client work.

Most social media scheduling tools now support LinkedIn carousel uploads, allowing you to create a month’s worth of carousels during a focused content creation session, then schedule them to publish during your optimal posting windows.

This workflow particularly suits law firms because it separates content creation (which benefits from focused time and clear thinking) from publishing timing (which must occur during specific windows when your audience is active). You can create educational carousels about employment law during a quiet Friday afternoon, then schedule them to publish on Tuesday morning at 9 am when your target audience of HR professionals is most active on LinkedIn.

Scheduling also enables consistency, which the algorithm rewards. Posting valuable carousel content every Tuesday and Thursday at 9 am trains both the algorithm and your audience to expect and engage with your content regularly, compounding your reach over time.

Measuring What Works

Creating carousels is only valuable if you’re tracking which topics, formats, and approaches actually generate results for your firm. LinkedIn provides analytics for all posts, including carousels, showing impressions (how many people saw it), interactions (likes, comments, shares, and swipes), engagement rate (percentage of viewers who interacted), and clicks (if you included a link).

For law firms, the metrics that matter most include:

Swipe-through rate: What percentage of people who saw your carousel swiped to at least slide two? Low swipe rates suggest your first slide hook isn’t compelling enough.

Completion rate: How many people swiped all the way to your final slide? High completion rates indicate your sustained interest in the content.

Comments and meaningful engagement: Are people asking questions, sharing experiences, or requesting consultations? This indicates your carousel resonated beyond passive consumption.

Profile visits and website clicks: Did the carousel drive people to learn more about your firm? This moves beyond engagement metrics to actual business development indicators.

Track these metrics monthly to identify patterns. If employment law carousels consistently generate more engagement than family law content, that reveals where your audience’s interests lie. If 10-slide carousels get higher completion rates than 15-slide versions, that suggests your ideal length. If certain hooks dramatically outperform others, you’ve discovered messaging that resonates.

Use these insights to continuously refine your carousel strategy, doubling down on what works rather than creating content based on assumptions.
