12 Claude Design Prompts for Social Media Posts (Copy and Paste)
6 October 2026 · 8 minute read
A Claude Design prompt for a social post works when it does five things: it names the exact canvas size, gives the copy word for word, picks one element to be the hero, describes the style in concrete terms, and lists what to leave out. The twelve prompts below all follow that structure. Paste one into Claude Design, replace the parts in square brackets with your own content, and you get a layout that needs one or two tweaks rather than ten.
What makes a Claude Design prompt work for social posts?
Claude Design is good at layout and typography, and it will happily fill any gap you leave with its own ideas. Most disappointing results come from those gaps: no size, so the canvas is wrong for the platform; no exact copy, so it writes filler; no hero, so everything competes; no constraints, so it adds icons and gradients you did not want.
| Part | Why it matters | Example |
|---|---|---|
| Canvas size | Sets the platform ratio before anything is drawn | 1080x1350, Instagram 4:5 |
| Exact copy | Stops invented headlines and placeholder text | Copy, exactly this and nothing more |
| One hero | Gives the eye one place to land | The number fills a third of the canvas |
| Concrete style | Colours and fonts, not adjectives | Cream background, #1F6F4A accent, serif |
| Leave out | Removes the decoration AI adds by default | No icons, stock photos or emoji |
If your brand is already set up as a design system in Claude Design, say "use our design system" in place of the colours and fonts. Everything else in the prompt stays the same.
Which prompts work for single-image posts?
These five cover most feed posts. Square 1080x1080 works on Instagram and LinkedIn alike; 1080x1350 portrait takes more room in the Instagram feed. The size guide has the full list of dimensions.
1. Quote card (1:1)
Design a 1080x1080 social post for Instagram and LinkedIn. Copy, exactly this and nothing more: - The quote, as the hero, in a large serif: "[Your quote, under 25 words]" - Attribution underneath, small: [Name], [Role] - Bottom corner, very small: [yourwebsite.com] Style: [cream] background, [near-black] text, one accent colour [#1F6F4A] used only for the opening quotation mark. Generous margins, left-aligned text, plenty of empty space. Leave out: icons, photos, gradients, decorative shapes, and any text I have not given you.
2. Statistic post (4:5)
Design a 1080x1350 Instagram post built around one number. Copy, exactly this and nothing more: - Small uppercase label at the top: [WHAT THE NUMBER MEASURES] - The number, as the hero, filling at least a third of the canvas: [73%] - One sentence under it: [of buyers read three reviews before choosing a supplier.] - Source line, small, at the bottom: Source: [Publisher, Year] Style: [deep navy] background, white text, the number in [bright yellow]. A bold sans-serif for the number, regular weight for everything else. Leave out: charts, icons, illustrations, extra copy.
3. Launch announcement (1:1)
Design a 1080x1080 launch announcement post. Copy, exactly this and nothing more: - Small uppercase eyebrow: NEW - Headline, two lines at most: [Product name] is live. - One supporting line: [What it does, in under 12 words.] - A button-style label at the bottom: [Try it free at yoursite.com] Style: brand colours [#hex, #hex] and the font [font name]. The headline is the hero. One simple shape (a circle or rounded rectangle) behind the headline is allowed. Leave out: product mockups, screenshots, emoji, stock imagery.
4. Event or webinar promo (4:5)
Design a 1080x1350 post promoting a live event. Copy, exactly this and nothing more: - Eyebrow: [LIVE WEBINAR] - Title: [Session title] - Date and time: [Thursday 14 November, 2pm GMT] - Speaker: with [Name], [Role at Company] - Footer: Free. Register at [link] Layout: the title is the hero in the top half. The date and time get their own clear block so they can be read in one second. Leave an empty circle at the bottom left as a placeholder for the speaker's photo. Leave out: icons, background photos, extra copy.
5. Customer testimonial (1:1)
Design a 1080x1080 customer testimonial post. Copy, exactly this and nothing more: - Five small stars at the top in [accent colour] - The testimonial, as the hero: "[Testimonial, under 30 words]" - Name and company, small: [Name], [Company] Style: white background, a thin [accent colour] border inset 40px from the edge, a serif for the quote and a sans-serif for the name. Leave out: photos, logos, any extra wording.
Which prompts work for carousels?
Carousel prompts need one extra instruction: every slide the same size, with the same margins and the same position for recurring elements, so the swipe feels smooth. On Instagram a carousel is a set of images; on LinkedIn it is a single PDF posted as a document. The Instagram and LinkedIn carousel guides cover the formats in detail.
6. Educational carousel for Instagram (4:5, 7 slides)
Design a 7-slide Instagram carousel as one slide deck, every slide 1080x1350. Slide 1 (hook): [How to write a cold email that gets replies]. Large headline and nothing else, apart from a small "Swipe" cue at the bottom right. Slides 2 to 6: one tip per slide. Each has a big number (01 to 05), a short tip title and one or two sentences of explanation: - [Tip 1 title]: [explanation] - [Tip 2 title]: [explanation] - [Tip 3 title]: [explanation] - [Tip 4 title]: [explanation] - [Tip 5 title]: [explanation] Slide 7 (call to action): [Save this for your next campaign.] and [@yourhandle]. Style: identical margins on every slide, with the number and title in the same position each time. Colours [#hex, #hex], font [font name]. Leave out: icons, illustrations, page numbers other than the tip number.
7. LinkedIn document carousel (4:5, 8 slides)
Design an 8-slide LinkedIn carousel as a slide deck, every slide 1080x1350. It will be posted as a PDF document, so every slide must be exactly the same size. Slide 1: headline [The 5 metrics our agency reports to every client], subtitle [and the 3 we stopped reporting], and my name at the bottom: [Name]. Slides 2 to 7: one idea per slide, a short heading and at most 30 words of body copy: - [Idea 1] - [Idea 2] - [Idea 3] - [Idea 4] - [Idea 5] - [Idea 6] Slide 8: [Follow me for more on agency operations] and [Name]. Style: [brand colours and fonts]. Body text no smaller than 32px so it reads on a phone without zooming. Leave out: stock photos, emoji, dense paragraphs.
8. Myth versus fact carousel (4:5, 5 slides)
Design a 5-slide carousel, every slide 1080x1350, in a myth versus fact format. Slide 1: headline [3 myths about (topic) that are costing you money]. Slides 2 to 4: each slide split into two stacked halves. The top half is labelled MYTH in [muted red] with the myth; the bottom half is labelled FACT in [green] with the correction: - Myth: [...] / Fact: [...] - Myth: [...] / Fact: [...] - Myth: [...] / Fact: [...] Slide 5: [Which one surprised you? Tell me in the comments.] Leave out: icons, illustrations, ticks or crosses beyond the two labels.
Which prompts work for thumbnails, banners and link previews?
These formats are wide and get cropped or covered in predictable places: the video length on a YouTube thumbnail, the profile photo on a LinkedIn or X banner, the edges of a link preview. The prompts tell Claude Design where not to put anything important.
9. YouTube thumbnail (1280x720)
Design a 1280x720 YouTube thumbnail. Copy, exactly this and nothing more: [3 to 5 words, e.g. I QUIT CANVA] Layout: the text takes up the left 60% in a very heavy sans-serif with a thick outline, so it reads at phone size. The right side is an empty rectangle where I will place a photo. Keep everything important away from the bottom right corner, where YouTube shows the video length. Style: high contrast, [yellow text on near-black]. Leave out: small text, more than five words, borders.
10. LinkedIn profile banner (1584x396)
Design a 1584x396 LinkedIn profile banner. Copy, exactly this and nothing more: - [Your positioning line, e.g. I help B2B SaaS teams turn webinars into pipeline] - Small line underneath: [yourwebsite.com] Layout: keep all text in the middle of the banner, roughly between 320px and 1270px across, and in the upper half. The profile photo covers the lower left, and phones trim both sides, so leave the left fifth and the right edge plain. Style: [brand colours], with at most one subtle pattern or gradient. Leave out: other companies' logos, icons, photos.
11. X header (1500x500)
Design a 1500x500 header image for X. Copy, exactly this and nothing more: [one short line, or no text at all] Layout: keep any text in the middle band, away from the lower left where the profile photo overlaps, and away from the top and bottom edges, which are cropped on some screens. Style: [brand colours and fonts]. Leave out: small text, busy patterns behind the text.
12. Link preview image (1200x630)
Design a 1200x630 link preview image (Open Graph image) for this article: [article title]. Copy, exactly this and nothing more: - The article title, as the hero: [article title] - Small line: [yoursite.com] Layout: keep all text inside the central 1000x500 area, so nothing is lost when an app crops the preview. Style: [brand colours and fonts]. Leave out: tiny text, screenshots, faces near the edges.
How do you adapt these prompts to your brand?
Swap the bracketed colours and fonts for your own, and give hex codes rather than names: "#0B3D2E" gets you the green you mean, "dark green" gets you Claude's idea of it. Name one font for headlines and one for body text. If you post often, build the brand once as a design system in Claude Design and start every prompt with "use our design system".
Keep the "copy, exactly this and nothing more" line even when you are happy for Claude to help with wording. Ask for copy in a separate message first, edit it, then paste the final words into the design prompt. Mixing the two is how a carousel ends up with a different tone on every slide.
When a result is close but not right, change one thing per follow-up message ("make the number larger", "move the date block up") rather than rewriting the whole prompt. Small edits keep the parts you liked.
How do you get the finished design out as an image?
For a single post, Claude Design's own export is often enough: each artboard can be saved as a PNG at 1x or 2x. It gets slower with a carousel, because each slide is exported one at a time, and there are no platform size presets, so it is on you to check the file is exactly what Instagram, LinkedIn or X expects.
Renda handles the batch version: drop the Claude Design export (or a file a teammate sends you), pick the size you designed for or let it detect the canvas, and download one sharp PNG per slide, a LinkedIn carousel PDF, or both at once. Because each prompt above names its canvas size, the render matches it exactly.
Frequently asked questions
Do these prompts work in ChatGPT or Claude chat?
Yes, with one addition: ask for "a single standalone HTML file" at the end of the prompt. Chat tools are less precise about layout than Claude Design, so expect another round or two of tweaks.
Why give Claude Design the exact copy?
Without it, Claude Design writes its own headline and body text to fill the layout. That text is usually generic, and it changes every time you regenerate. Fixed copy keeps every revision comparable.
What size should a social media post be?
1080x1350 (4:5) for Instagram feed posts and carousels, 1080x1080 for posts shared to several platforms, 1080x1920 for Stories and Reels covers. The size guide covers every platform.
Can Claude Design make a whole carousel from one prompt?
Yes. Ask for a slide deck with a fixed slide size and describe each slide in order, as in prompts 6 to 8. Then see the Claude Design carousel workflow for iterating slide by slide.
