Facebook uses different crops on desktop and mobile, especially for covers. These are commonly recommended sizes, not official limits.

Why Facebook images need resizing for Pinterest
Facebook images come in many shapes, but the most common one for bloggers and brands is the wide link share image at roughly 1.91 to 1. That shape is the opposite of a Pinterest pin. Pinning it directly produces a short, wide strip that is easy to scroll past. Resizing a Facebook image for Pinterest means turning a landscape into a portrait without losing the message.
For wide link images and page covers, color fill is often the best start. It places the full image in the middle of a 2:3 canvas on a solid color, leaving clean space above and below for a title in the pin maker. Square and 4:5 posts behave like Instagram posts: blur fill or a gentle crop works well.
Tips for converting Facebook images
Wide images need a new layout
Cropping a 1200 by 630 image to 2:3 keeps only about a third of its width. Use color or blur fill to keep everything, then add a title above or below.
Covers are banners, not pins
Page covers are very wide. Use them as a strip inside a taller pin rather than cropping, since text on covers is usually spread across the full width.
Match your brand color
Color fill lets you pick any color. Using your brand color for the fill turns the empty space into a consistent frame across all your pins.

Facebook to Pinterest FAQ
How do I resize a Facebook image for Pinterest?
Upload the image, choose Standard pin, and pick color fill for wide link images or blur fill for square posts. Download the JPG or PNG and add a title in the pin maker if you like.
Why does my Facebook link image look small on Pinterest?
It is wide and short, around 1.91 to 1, while pins are tall at 2 to 3. Pinterest shows images by width, so a wide image takes up much less height in the feed.
Should I crop or fill a Facebook cover?
Fill, in most cases. Covers are very wide and usually hold text or faces across the whole width, so a crop would cut them off.
