Sprite Character Pixel Size Issues Paper 2D

Hi. I’m pretty new to UE4 and am trying to make a Paper 2D game like mario. My problem is I have two flipbooks: idle and shoot (my character shoots arrows). When I switch to the shoot flipbook, my character is smaller than when he is idle. Though the arrow (projectile) adjusts itself based on the character size. Both the sprites in the idle flipbook and shoot flipbook are 12001200 pixels. The default flipbook for my character when I open it’s blueprint is idle. Though when I open the sprites themselves the approx size for idle is 1901950. While for shoot it is 360 1*679. Similarly, I have a Jump flipbook which is correct size (working how I want it) but when I open individual sprites it matches approx. size with idle. Any ideas? Let me know if you need more info. Thanks in advance
