Hi

In this Theme we have designed and developed in different way. This theme is designed in a grid Layout so fit the grid layout on template, the Images are used as a background so it get covered and fit to the parent Frame size.
and since the images you have used are not of same size so the above solution for you won’t work if you see on MagCast Theme the image rendered are not equal and same size and these are different in these theme.

If you don’t want to make the image get cover and also want to show full image within the frame size without crop then please go to ‘Appearance > Customize > Additional CSS’ and paste the below Code.

.post-img-wrap:before,
.page-single-img-wrap:before {
	padding-top: 56%;
}
.post-img-wrap .post-img,
.page-single-img-wrap .post-img {
	background-size: contain;
	background-position: top center;
}
.post-boxed.inlined .post-img-wrap,
.page-single-img-wrap {
	background-color: #ffffff;
}

Thanks
