Visual storytelling on LinkedIn: infographics, charts, and carousels

Visual storytelling on LinkedIn is a choice among three files. An infographic or a chart is a picture. A multi-image post is several pictures in a grid. A carousel, in the 2026 feed, is a document: one PDF, PowerPoint, or Word file that LinkedIn shows a page at a time. LinkedIn does not publish an "infographic" post type. The word is a design habit. The upload box only knows photos and documents.

Boykli builds two of the outputs people mix up here, and they stay separate. The carousel page returns a 2 to 8 slide PDF, square or portrait, plus a title and a caption. Image generation returns one picture, in one of four styles, and that picture is not a plotted chart. A spreadsheet, a dashboard screenshot, and a Canva chart stay where you drew them. This page is the decision before either file: which object the reader needs, which numbers you are willing to sign, and which design name matches a deck that is mostly figures.

How a photo grid differs from a PDF on layout and on rate is multi-image vs carousel. The pixel contract for the PDF is LinkedIn carousel dimensions. The 3× dwell line, and the company-page rates that are actually published, sit in carousel engagement rate.

Three objects, one feed

Share photos on LinkedIn is the photo article. One image, or up to 20. Each upload is limited to 5 MB in that article. The minimum size named there is 552 by 276 pixels, with 1080 pixels of width recommended. Aspect ratio runs from 3:1 to 4:5. A wider or taller file is centered and cropped. After the post is live, those photos cannot be resized or edited. Each image can take alternative text. The same article says a post can carry a URL preview or an image, and not both.

Upload and share documents is the document article. One PPT, PPTX, DOC, DOCX, or PDF, up to 100 MB and 300 pages. You add a title, then a description. After publish you can edit the description. You cannot replace the file. Anyone who can see the post can download it as a PDF. LinkedIn shows a page at a time, in file order, with the document title.

Media file types supported on LinkedIn lists JPEG, PNG, GIF, and WEBP for images, HEIF/HEIC on iOS, and the same document set. Its notes cap a file at 100 MB, a document at 300 pages, and an image at 36 megapixels. Read the photo article's 5 MB line as the per-photo share-box limit.

Three hundred pages and twenty photos are ceilings. A chart that needs a legend on a second frame has already failed as a single image. A 40-page PDF is a leave-behind, and the page counter tells a skimmer the length before they start. Boykli stops the carousel form at 8.

What an infographic is doing in this feed

An infographic, as people use the word on LinkedIn, is one picture that packs a claim, a few figures, and the labels those figures need. The reader finishes it without swiping. That is a strength when the comparison is small: two bars, one before-and-after, a three-step diagram with the verbs on the art. It is a failure when the type is 11 pixels on a phone, or when the point lives in a footnote the crop cut off.

The photo article's aspect window is the crop. A 16:9 dashboard exported as a JPEG becomes a short strip, or it gets letterboxed and then cropped toward 4:5. Portrait room is the 4:5 edge, about 1080 by 1350 if you design to the tall end of the allowed window. Square 1080 by 1080 sits inside the window and wastes less of a centered chart. Design the picture at the size LinkedIn will keep, then export. Do not design a poster and hope the share box invents a readable scale.

Alt text is the sentence a screen reader gets. Write the claim and the numbers in that field. "Chart" is not alt text. "Invoice exceptions fell from 14% to 3% between March and August 2026" is.

A single generated image on Boykli is a different object from that designed chart. Create posts can attach one picture: Weird metaphor, Flat illustration, Photo of the topic, or Comic. Those styles illustrate a topic. They do not plot your series, label your axes, or import a PNG you already finished. If the visual is a real chart, draw it in the tool that holds the data, export inside the photo limits, and upload that file in LinkedIn's composer. If the visual is a metaphor for the post, the image generator is the path, and it draws from the image allowance on Managed (150 a month), separate from the 150 carousel generations.

What a chart has to survive

A chart on LinkedIn is a reading test, not a decoration. Four questions decide the file:

1. Can a person name the comparison from the first screen, without a legend on another page?
2. Are the numbers ones you would repeat on a call tomorrow, with the window and the exclusion in the same breath?
3. Does a later mark change the meaning of an earlier mark? If yes, you have a sequence, and a single JPEG is the wrong object.
4. Is the chart a picture of software (a dashboard, a screenshot, a plotted image), or a few figures that can be set in type?

Picture-of-software stays a picture. Boykli slides are HTML and CSS: type, shapes, gradients, and SVG. They do not place a photograph, a product screenshot, or a chart that is an image. The same limit is why a Figma frame with a real plot stays in Figma, and why a Canva chart stays in Canva. Those paths are Figma to a LinkedIn carousel and Canva to a LinkedIn carousel. Redrawing the chart as a sentence is a different deck. Leaving the image in the design tool is the honest path when the picture is the argument.

A few figures that can be set in type are a carousel job, or a very spare single image you build yourself. On the carousel page, the design named Infographic / Data Guide is the layout for that job when brand colors are off. The instruction to the model is a structured display: grids or flex groups, bordered cards with a 12px radius and a hairline border, a key stat around 72px at weight 800, a modern sans, and colored progress bars or badges. Those bars are CSS drawn from the words in your topic. They are not a chart library reading a CSV. If the topic says "14% to 3%" and never says the months, the bar has no honest scale. If the topic invents "pipeline up 40%," that invention can render as a huge stat, and once the PDF is on LinkedIn the file cannot be swapped.

Huge type is a choice with a cost. A 72px number needs a label in the body ramp, which floors near 21px, or the stat is a billboard with no unit. Density on these slides is capped around five bullets or four cards. A sixth figure is a new slide, not a smaller font. Overflow is hidden, so a line that does not fit is clipped. The full ramp, including the 64–100px stat callout, is in LinkedIn brand kit.

Brand colors change which design you may use. Canvas, accent, logo, profile photo, and handle live on the carousel page. If colors are included and at least one hex is saved, the only design available is Normal. Infographic / Data Guide, Neo-Brutalist, Bauhaus, Retro Terminal, Bold & Edgy, Creator Gradient, and Split-Screen stay in the menu and stay disabled until brand colors are off. Logo and the author strip still work on those seven. Normal can still carry a large stat and a card. It will not copy the Infographic card chrome, because that chrome has its own palette, and mixing your hex into it is the muddy file the lock exists to prevent. The eight looks, and which one is the quiet custom deck, are in minimalist carousel templates.

The bottom 220 pixels of every slide is reserved when the logo or the author strip is on. Cover headlines and the big stat stay above that band. A number parked in the footer gets covered by the handle pill.

When the sequence is the carousel

Use the PDF when page 3 is nonsense without page 2. A definition, then the measurement window, then the exclusion, then the rule someone can copy: that is four pages of one argument. A grid would show several of those pages at once and crop the bottom row. A single infographic would shrink the exclusion until it is decoration.

Square renders at 1080 by 1080. Portrait renders at 1080 by 1350. The PDF page size that matches, at 192 PPI, is 810 by 810 pt or 810 by 1012.5 pt. That measurement is LinkedIn PDF slide dimensions. Portrait is the right ratio when each stat is a number plus a sentence. Square is the right ratio when each slide is one number and a short label. Split-Screen is the wrong design for a 420-pixel column asked to hold "14% to 3%, March to August, exceptions only." Two columns fit a comparison of two short claims, not a chart legend.

Slide count is 2 to 8. The default on the form is 5. A cover, three figures, and a close fits 5. A teardown that needs the exclusion on its own page often wants 6 or 7. Past 8, the form stops. A longer leave-behind is a file you upload yourself, inside the 100 MB and 300 page ceiling, and Boykli does not import that finished PDF as editable slides.

The caption still has to contain the point. A cover that says "the number is on slide 6" is a slowed thumb. Engagement bait versus a post that already contains the point is the caption test, separate from format. Put the result in the first lines. Let the PDF show the window, the exclusion, and the rule.

Which visual for which job

Socialinsider's company-page tables, and why they are not a personal-profile multiplier, are already worked in the engagement-rate guide. Use them to retire a fake "carousels always win" rule. Use the table above to pick the file. Then run one pair on your own profile if the format is still a debate: same claim, different days, impressions and members reached written down. Combined analytics are an estimate, and they are not a dwell export.

A workflow for one number you can sign

This is the path for a founder who has a real before-and-after and wants it readable on a phone. The example is invoice exceptions falling from 14% to 3% between March and August 2026, after fuzzy matching stopped. Swap in your figures. Do not keep these ones if they are not yours.

1. Write four lines before you open a tool. The result: 14% to 3%. The window: March through August 2026. The exclusion: credit notes and invoices under $50 stayed out of both rates. The rule: match on the document id, and a human reads whatever is left. If you cannot write the exclusion, you do not have a chart yet. You have a slogan.
2. Decide the object. One person can hold "14 to 3, six months, small invoices out" in a single frame. That can be one designed image. The moment you also need "what we match on now," "what we stopped," and "who reads the queue," you have a sequence. Build the PDF. Do not slice the same bar into six slides to manufacture swipes.
3. For the single image, build it outside Boykli at 1080 wide, inside 4:5, under 5 MB, labels on the art, alt text equal to the four lines. Upload it in LinkedIn's composer. Boykli's image styles will not draw this chart. A generated metaphor beside a caption that states the four lines is a different post, and it should not pretend to be the plot.
4. For the PDF, open the carousel page on Boykli. The topic box holds up to 2,000 characters. Paste the four lines, then the shape: "Cover: 14% to 3%, March–August 2026. Slide 2: the exclusion. Slide 3: match on document id. Slide 4: what we stopped fuzzy-matching. Slide 5: who reads the leftover queue. Close: the rule in one sentence. Do not add other findings." How a topic, an idea, or a file becomes that PDF is LinkedIn carousel generator.
5. Set the count to 6. Tone stays Normal unless the deck is actually a joke. Humor changes wording only. It does not restyle a measurement. Ratio is Portrait, because several slides are a number plus a sentence. Square if you cut each slide down to the figure and a four-word label.
6. Design: Infographic / Data Guide when brand colors are off. Normal when colors are on. Neo-Brutalist if you want the deck to look less like a report and you accept its own flat palette. Save the brand kit before you create. An unsaved color change blocks the button. The model list is Grok 4.6 (the default), Gemini 3.5 Flash, Claude Sonnet 5, or GPT-5.6 Terra. There is no silent swap.
7. Read every slide. A bar that says 40% because the model rounded, a month you did not name, or a "source: industry benchmark" you did not write is still your post. Fix it by changing the topic and creating again. The editor does not offer a chart widget you can drag. The words are the data.
8. Set the document title, up to 120 characters. That string is the name of the PDF on LinkedIn. Write the caption with the result in the first lines, then the exclusion. The title and the caption are stored separately. Publishing uses the title as the document name and the caption as the commentary.
9. Check the phone column. The stat sits above the 220px band. The unit is on the same slide as the number. No slide exists only to say "swipe." Preview how the caption truncates is LinkedIn post preview.
10. Download the PDF, post it on the personal profile you connect, or queue it. Company pages, other networks, and a teammate's approval step are outside this product. The file LinkedIn receives cannot be replaced after publish, so the read in step 7 is the last technical check that matters. Scheduling that document is how to schedule a PDF on LinkedIn.

Managed includes 150 carousel generations a month and 150 images a month. BYOK is $29 a month on your own model keys, with no Boykli monthly generation cap. Managed is $88 a month. Opening the site does not require a plan. Creating the PDF does. Radar and Algorithm stay browsable without a seat.

What fails in public

A 16:9 board slide, uploaded as the document, becomes a short strip on a phone. The chart is technically "on LinkedIn." It is not readable. Rebuild at 1080 square or 1080 by 1350, or accept that the leave-behind belongs in the comments as a file people download on purpose, not as the feed object.

Exporting the PDF's pages as separate PNGs and uploading those as a multi-image post throws the sequence into the grid. The first slide becomes a column or a header. A later slide can be cropped. That test does not measure the carousel. It measures the grid. If you want the order, upload the PDF.

A progress bar with no denominator is decoration. "Quality up" with a full green bar teaches nothing a sentence would not teach faster. Either print the two rates, or drop the bar.

Tagging a colleague on the chart so they are notified is a different action from publishing the file. The Boykli queue does not mention people. How @mentions work, and why a photo tag is another control, is how to tag people on LinkedIn.

FAQ

Does LinkedIn have a native infographic format?

No. You upload a photo or a document. An infographic is a picture you designed. A carousel is the document post. The feed chrome (a grid, or a page counter and a title) comes from which upload you used.

Do carousels get more reach than charts?

LinkedIn has not published that ranking. A chart that is one image is scored against similar images. A PDF is scored against similar documents. Dwell is relative to the format, which is why a longer file is not a published multiplier. Company-page engagement rates from Socialinsider are cited and limited in the carousel engagement guide. On your profile, compare a matched pair and read members reached beside the rate.

Can Boykli turn a spreadsheet or a dashboard into a chart?

No. There is no CSV import and no chart plotter. Infographic / Data Guide can set numbers you typed as large type, cards, badges, and CSS bars. A dashboard screenshot stays an image you upload yourself. A source PDF's embedded charts do not become pictures on the new slides. If a figure matters, write the claim into the topic.

Will a chart I paste into the topic be checked?

The model writes the lines from your topic. It can also introduce a figure you did not supply. You have to read the slides. After LinkedIn has the file, you can edit the caption and you cannot replace the PDF.

Square or portrait for a stat deck?

Portrait (1080 by 1350) when the slide is a number plus the sentence that makes the number true. Square (1080 by 1080) when the slide is one figure and a short label. Both are inside what a document post accepts. The single-image crop rules are a separate limit and do not apply to the PDF.

What if I want my brand colors on a data deck?

Turn brand colors on, save the kit, and use Normal. Infographic / Data Guide is disabled while those colors are included. You still get a large stat and cards. You do not get that design's own highlight palette mixed with your hex. Logo and handle can stay on.

Can I schedule the carousel?

Yes, on the personal profile you connect, as a document post. The queue sends the PDF and the commentary. It does not build a multi-image gallery, and it does not post the chart to a company page.
