Hi
No the height and width is not same on your site. Kindly re check all images not same, also the text is different.
Each item will change its width and height based on the content in it.
For example add this code in custom css
.acm-teams .team-items .item {
max-height: 489px;
}
490px is max height of an item on your site whose height is small so this code will force the item heigh to 490px. Or you can use same type of content and images.
