You can change the size of the embedded player by clicking the "+ Show options" link in the window that opens after you click the Share button on any video.
Once you've entered the new dimensions, copy the embed code and paste it into your destination of choice.
You can also grab the embed code from the embed section of your video’s settings page.
Once you obtain the embed code, you can adjust the height and width values before pasting into your webpage builder. We recommend using dimensions that yield the same aspect ratio as your original file; for example, if your video is 1920 x 1080, you’ll want to use dimensions that yield an aspect ratio of 16:9 like 640 x 360.
Styling the Vimeo iframe
The size and position of the player iframe can be influenced by the styling of your webpage. This is common when using pre-built themes or plugins in webpage builders such as Wordpress, Wix, or Squarespace. If you are setting the dimensions in your embed code correctly, but the Vimeo player is displaying differently, we suggest checking your webpage builder to see if any additional formatting is being applied to the player iframe.
If you’re not sure, contact us and we’ll take a look. Be sure to include the URL of your webpage as well as any login information required to access it.
Our iframe embed code is not responsive by default. In other words, the Vimeo player will not adjust according to your screen or window size if you’ve inserted the default embed code. To make the player responsive, we recommend using the Vimeo option under http://embedresponsively.com/. You can also create your own solution by using a third party plugin or applying custom styles to the player iframe.
