How are you inserting the poll slides into your slide deck? We recently added some handling to our PowerPoint add-in to match the size of the poll slide to the default size of the master slide in the deck. However, this is only when you are inserting from within our PowerPoint add-in, not when you download slides from our website.

I’d recommend trying this:
1. open your powerpoint deck
2. navigate to the Poll Everywhere app and open the modal
3. click the checkmark for whichever polls you would like to insert and click the Insert button

That method should have our poll slides match the size of your own slides. You can read some more about our slideware integration here if you have trouble or more questions: https://www.polleverywhere.com/guides/presenter/getting-started#presenting-in-a-slideshow

Thanks for the feedback!
