Hi Dale,
Congratulations on your new iPhon 8! I understand that you'd like the icons to be larger like they were on your previous iPhone, and I'm happy to provide some help for this.
I recommend using the steps in the article below to enable Display Zoom:
Magnify the screen with Display Zoom - iPhone User Guide
On supported devices, you can magnify the screen display. Go to Settings > Display & Brightness. Tap View (below Display Zoom), choose Zoomed, then tap Set. For additional zoom features, see Zoom.
Thanks for using the Apple Support Communities. Cheers!
