Question about responsive design on big screen

Hello everyone, I’m beginner with webflow and front-end web design…
I have simple questions how to make website to look same on every screen size
I have iMac 27inch and screen is very big, I see that mostly the design is done on 1440px(canvas size in figma) and i my design looks good on 1440px canvas size but when I start making design in webflow everything look so small and my design don’t look like design in figma…
I hope you will understand me, thank’s in advace!
