Most Pinterest pins fail for mechanical reasons you can fix in ten minutes: the wrong aspect ratio, text that vanishes at thumbnail size, or a file that gets compressed into mush. Here is the do-this-not-that version, with the numbers behind each choice.
Advertisements1
- Export at 1000×1500 px (2:3) and keep files under 2 MB — Pinterest re-encodes everything you upload.
- A 1000 px canvas displays at roughly 236 px wide, so headlines need to be 90–120 px to survive the thumbnail.
- Optimize for saves or outbound clicks deliberately; they respond to different image choices and should be measured separately.
- Judge variants on rate per impression, not absolute totals — 55 saves from 2,500 impressions beats 60 from 4,000.
- Give pins 30 days before deciding; early deletion costs you the comparison data and the historical engagement.
Pin the 2:3 ratio — 1000×1500 px is the working standard
Pinterest renders pins in a vertical feed, and the platform's own guidance points to a 2:3 aspect ratio. A 1000×1500 px file hits that ratio at a size that survives compression on mobile and desktop without bloating your upload time.
Do this: export at 1000×1500 px, keep the file under 2 MB as a PNG or high-quality JPG. Don't upload a 4000 px original and assume Pinterest will preserve the detail — it re-encodes and downsamples, and oversized files just slow your workflow.
Not that: square 1:1 images or 16:9 crops. A square pin occupies roughly 66% of the vertical space a 2:3 pin does in the same feed slot, so you're paying the same attention cost for less visual real estate. If your source photo is landscape, crop to 2:3 rather than letterboxing with white bars — bars read as unfinished.
One more number: tall infographic pins at 1:2.1 (1000×2100) can work for step-by-step content, but anything beyond 1:2.5 gets truncated in-feed with a "More" cut. Test one tall format against your standard before committing a whole board to it.
Design text for a 236 px-wide thumbnail, not your 1000 px canvas
Here's the calculation that changes how you design. On a typical mobile feed, a pin displays at roughly 236 px wide. Your 1000 px canvas is shown at 23.6% scale. A 40 px headline on your canvas renders at about 9.4 px on screen — borderline unreadable.
Do this: set your headline at 90–120 px on the 1000 px canvas so it lands at 21–28 px in-feed. Body or supporting text should be no smaller than 50 px canvas size (about 12 px rendered). Preview at 25% zoom before you export; if you can't read it, neither can the scroller.
Not that: cramming a full sentence of explanation onto the image. The pin's job is to stop the scroll and promise a specific outcome. Detail belongs in the destination article. A useful ceiling: 6–9 words for the headline, 0–5 words for a secondary line.
Contrast matters as much as size. White text on a mid-tone photo fails; add a 40–60% opacity dark overlay behind text blocks or place text in a solid color band. Test your pin in grayscale — if the text disappears, your color contrast is doing all the work and it will fail for colorblind viewers and on low-brightness screens.
Match the image to the intent: saves, clicks, and the difference
Not every pin should chase the same metric. Saves and outbound clicks respond to different image choices, and knowing which you're optimizing for prevents wasted design hours.
For saves: use a clean, aspirational image with a short benefit headline and a small brand mark. Reference-style content (checklists, "10 ideas for," ingredient or supply flat-lays) earns saves because people file it for later. Expect save rates in the 0.5–2% range of impressions for solid pins; outliers exist but don't plan around them.
For outbound clicks: put a concrete promise plus a curiosity gap on the image — "The 3 measurements that fix a bad shelf fit" beats "Beautiful Shelving Ideas." Add a subtle directional cue (an arrow, a partial reveal, a before/after split) and keep the brand mark small and bottom-corner so it doesn't compete with the hook.
Not that: identical images across every board with only the title changed. Pinterest's visual search reads the image itself; near-duplicate creative gets deduplicated in distribution. Vary the photo, the crop, or the text overlay between variants — three genuinely distinct creatives beat ten recolors.
Put the keyword in the image text and the alt text, not just the title
Pinterest is a visual search engine, and it reads more than your pin title. The text baked into your image is part of how the pin gets understood and matched.
Do this: include your primary phrase in the on-image headline where it reads naturally ("Small Kitchen Storage" rather than "Storage"), and write real alt text in the pin's description field — 100–200 characters describing what's in the image plus the topic. Alt text is also an accessibility requirement, not an SEO trick.
Not that: stuffing five keyword variations into the image text. It looks spammy, hurts legibility at thumbnail size, and dilutes the hook. One clear phrase per pin.
A practical workflow: build a simple naming convention for your files (topic-keyword-format.png) and keep a spreadsheet of pin title, on-image headline, alt text, and destination URL. When a pin underperforms, you can see whether the variable was the image or the copy. Without that record you're guessing.
Compression, file format, and the details that quietly kill quality
Pinterest re-compresses every upload. Your job is to hand it a clean file so the second compression has less to destroy.
Do this: export JPGs at quality 80–90 for photographic pins, PNG for flat graphics with sharp text and few colors. Keep text on flat color fields rather than over busy photo texture — compression artifacts show up first in high-frequency detail like small serif text over foliage.
Not that: uploading a screenshot of a design, or a file with a color profile mismatch. Export in sRGB; Adobe RGB files can shift noticeably after upload. And avoid thin 1 px hairlines in graphics — they often vanish entirely after re-encoding.
One risk to flag: if you use stock photography, check the license terms for commercial and derivative use before overlaying text. A pin that performs well and gets repinned widely amplifies any licensing problem you have. The cheap fix now is cheaper than the takedown later.
Test in batches of three, and give each pin 30 days
Pinterest distribution is slow compared to other feeds. Pins can sit quiet for weeks and then pick up. Judging a design after 48 hours produces bad decisions.
Do this: publish three distinct creatives for the same destination URL, spaced a few days apart, and review at the 30-day mark. Compare saves per impression and outbound clicks per impression separately — a pin can win one and lose the other.
Sample calculation: Pin A gets 4,000 impressions and 60 saves (1.5%); Pin B gets 2,500 impressions and 55 saves (2.2%). Pin B is the stronger creative despite fewer absolute saves — it earned them more efficiently. If you only look at totals, you'll keep the weaker design.
Not that: deleting underperformers early. Archived or deleted pins take their historical engagement with them, and you lose the comparison data. Leave them up; just stop making that variant.
How to Do It, Step by Step
- 1Set your canvas to 1000×1500 px
Lock the 2:3 ratio before you place any element. This prevents last-minute rescaling that softens text and shifts your layout. - 2Size the headline at 90–120 px
Preview at 25% zoom to simulate the mobile feed. If the headline isn't instantly readable, enlarge it or cut words. - 3Add a contrast layer behind text
Use a 40–60% dark overlay or a solid color band. Check the pin in grayscale to confirm the text still separates from the background. - 4Write the on-image headline as a specific promise
Aim for 6–9 words naming a concrete outcome. Move explanation to the destination article. - 5Write 100–200 characters of real alt text
Describe the image and include the topic phrase once. This serves accessibility and helps Pinterest understand the pin. - 6Export in sRGB at JPG 80–90 or PNG
Keep the file under 2 MB. Avoid 1 px hairlines and small serif text over busy photo texture. - 7Publish three distinct creatives per URL
Vary the photo, crop, or overlay — not just a color swap. Log each variant in a spreadsheet with title, headline, alt text, and URL. - 8Review at 30 days on rate, not totals
Compare saves and outbound clicks per impression across variants. Keep the winner and stop producing the losing format.
Design for the 236-pixel thumbnail, not the 1000-pixel canvas — that single shift fixes most underperforming pins.
Frequently Asked Questions
What is the best image size for Pinterest?
1000×1500 px, which is the 2:3 ratio Pinterest recommends for standard pins. It's large enough to stay sharp after compression without slowing your upload workflow.
How much text should I put on a Pinterest image?
Six to nine words for the headline and no more than five for a secondary line. Detail belongs in the destination article, and long text becomes unreadable at thumbnail scale.
Does Pinterest read the text on my image?
Yes, on-image text and your alt text both contribute to how the pin is understood and matched in search. Use one clear topic phrase rather than multiple keyword variations.
Why is my Pinterest pin blurry after uploading?
Pinterest re-compresses every file, which destroys fine detail first. Export in sRGB, avoid thin hairlines and small serif text over busy photos, and use PNG for flat graphics with sharp type.
How long before I know if a Pinterest image is working?
Give it 30 days. Pinterest distribution is slow, and pins often pick up weeks after publishing — early judgments based on 48-hour data lead to discarding designs that would have performed.
