Need help making iPad 13 screenshot

Can't you just use the iPad 13 Simulator via Xcode?

thank you for your response - however, I only have a Lenovo Intel based laptop - xcode is not an option

Right, well, information like that should be provided upfront so we can offer appropriate help.

Okay, what size screenshots for an iPad do you have?

You could always use a smaller image, like one for the 11-inch iPad, and scale it up to the right dimensions.

Or, you could make an image that fits the 13-inch size requirements but contains the 11-inch image instead. Think of a gradient coloured background with an image of an 11-inch iPad showing your app, and having some text at the top or bottom. Take a look at other apps on the Store, and see what they do with their screenshots.
