Schedule Pins. Where the image is the entire post.
Pinterest is a search engine that happens to look like a feed, and the image does nearly all the work. So the scheduling job is mostly about getting the aspect ratio right and keeping a steady cadence rather than agonising over copy.
One image per Pin, resized correctly.
The image is the post
There is no version of a successful Pin that is carried by its caption. The image decides whether anyone stops, and the description decides whether it gets found later.
That makes two things worth caring about:
Aspect ratio. Pinterest is a vertical surface. A landscape image submitted as a Pin gets cropped or rendered small, and either way it competes badly. The free image resizer exports at the recommended dimensions per placement and runs entirely in your browser — nothing uploaded, no watermark.
Description as search text. Pinterest behaves like a search engine. The description is not a caption to be clever in; it is where you put the words someone would actually type. The table above shows how much room you have, and it is tighter than the caption-heavy platforms.
Cadence over volume
Pins have a much longer useful life than a post on a feed platform — something pinned months ago can still be driving traffic. The practical implication is that a steady trickle beats a burst.
That is exactly what evergreen recycling is for: tag your Pins and let a rule bring them back on a cadence, with a cooldown so the same image is not reappearing every week.
The limits above render from the same rules the publish worker enforces, so the media count and accepted types are what will actually go out.

Questions
Frequently asked questions Everything the first evaluation usually needs.
- Can I schedule Pins in advance?
Yes, through Pinterest’s official API. Pins publish at the scheduled time with no action needed from you.
- What image size should I use?
Pinterest favours tall images, and a Pin at the wrong aspect ratio is cropped or shown small. The free image resizer exports at the recommended dimensions for each platform placement, in your browser.
- How many images can one Pin carry?
One — see the table above. A Pin is a single image or video, which is why the resizer matters more here than the media count.
- How much description text can I write?
Less than you might expect, and the table above shows exactly how much. Pinterest descriptions do searchable work, so use the space for words people would type rather than for a caption.
- Does Pinterest support a first comment?
No. First comments exist on Instagram, Facebook, LinkedIn, and Threads only.
