If you've been posting square or landscape images to Pinterest and wondering why your reach is low, the format is likely the problem. Pinterest is a vertical-first platform, and its algorithm actively favors tall images over wide ones.
This isn't just a design preference — it's baked into how Pinterest displays content. Vertical pins take up more screen space in the feed, which means more visibility, more impressions, and more clicks.
Why Vertical Images Dominate Pinterest
Pinterest's feed is a masonry grid. Every pin gets the same width, but the height varies based on the image's aspect ratio. A tall image occupies significantly more vertical space than a square one — which means it's harder to scroll past.
Studies and Pinterest's own creator data consistently show that vertical pins with a 2:3 ratio outperform square and landscape images in saves, clicks, and overall reach. The platform's algorithm also gives preferential treatment to pins that match its recommended formats.
The Exact Pinterest Image Sizes for 2026
Standard Pin (Most Common)
- Dimensions: 1000 × 1500 px
- Aspect ratio: 2:3
- Best for: Blog posts, recipes, tutorials, product pins
This is the sweet spot. It's tall enough to dominate the feed without being so tall that Pinterest truncates it.
Long Pin / Infographic
- Dimensions: 1000 × 2100 px (max before truncation)
- Aspect ratio: 1:2.1
- Best for: Step-by-step guides, infographics, before/after content
Pinterest truncates pins taller than a 1:2.1 ratio in the feed. The full image is visible when someone clicks through, but the feed preview gets cut off. Use this format intentionally — the truncation can create curiosity and drive clicks.
Square Pin
- Dimensions: 1000 × 1000 px
- Aspect ratio: 1:1
- Best for: Product shots, quotes, brand content
Square pins work, but they underperform vertical pins in most categories. Use them when the content genuinely suits a square format.
Pinterest Story Pin (Idea Pin)
- Dimensions: 1080 × 1920 px
- Aspect ratio: 9:16
- Best for: Multi-page tutorials, behind-the-scenes content
| Format | Width | Height | Ratio |
|---|---|---|---|
| Standard pin | 1000 | 1500 | 2:3 |
| Long pin | 1000 | 2100 | 1:2.1 |
| Square pin | 1000 | 1000 | 1:1 |
| Idea Pin | 1080 | 1920 | 9:16 |
File Specs That Matter
- Max file size: 20 MB
- Formats: JPG, PNG, WebP, GIF (static)
- Color space: sRGB
- Minimum width: 600 px (but always use 1000 px or wider for quality)
What Makes a Pinterest Pin Actually Get Clicked
Getting the dimensions right is the foundation. Here's what separates pins that get saved and clicked from ones that get scrolled past:
Use Text Overlays Strategically
Pins with descriptive text overlays consistently outperform image-only pins. The text should explain what the pin is about — think of it as a headline. Keep it short (5–8 words), use a readable font, and place it in the upper two-thirds of the image where it's visible in the feed preview.
Choose the Right Color Palette
Pinterest's own research shows that warm colors (reds, oranges, pinks) tend to outperform cool colors (blues, greens) in most categories. High-contrast images also perform better than low-contrast ones.
Include a Clear Subject
Pins with a clear focal point — a dish, a product, a person, a finished craft — outperform abstract or busy compositions. The viewer should understand what the pin is about within one second.
Optimize Your Pin Description
The image gets the click, but the description helps with Pinterest SEO. Include your target keyword naturally in the first sentence. Pinterest's search algorithm uses pin descriptions to categorize and surface content.
How Pinterest Displays Pins on Different Devices
On desktop, Pinterest shows 5 columns of pins. On mobile, it shows 2 columns. This means your pin needs to be readable at a fairly small size — especially any text overlays.
Test your pin by viewing it at 200 px wide. If the text is still readable and the main subject is clear, you're in good shape.
Resize Your Images for Pinterest
If your images aren't in the right format, you can convert them quickly without redesigning from scratch.
Set the output to 1000 × 1500 for standard pins, or 1000 × 2100 for infographics, and download a Pinterest-ready file.
Frequently Asked Questions
What is the best Pinterest image size in 2026? The best size for standard pins is 1000 × 1500 px at a 2:3 aspect ratio. This format takes up the most feed space without being truncated, and Pinterest's algorithm favors it.
Do vertical images really perform better on Pinterest? Yes, consistently. Vertical pins at 2:3 take up more screen space in the masonry grid, which increases visibility. Pinterest's own creator guidelines recommend vertical formats for this reason.
What happens if my Pinterest image is too tall? Pinterest truncates images taller than a 1:2.1 ratio in the feed preview. The full image is visible when someone clicks the pin, but the feed shows a cropped version. This can work in your favor for infographics — the truncation creates curiosity.
Should I use JPG or PNG for Pinterest? JPG for photos and gradient-heavy designs. PNG for graphics with text, logos, or sharp edges. Both work well on Pinterest.
How do I make my Pinterest pins show up in search? Pinterest SEO depends on three things: your pin title, your pin description, and your board name. Include your target keyword naturally in all three. The image itself also matters — Pinterest uses visual search, so clear, high-quality images rank better.
