Choose Medium
Medium decals work well above dressers, desks, and compact beds.
They provide a focal point without using most of the wall.
Choose Large
Large designs suit nursery focal walls and wider furniture.
Measure the completed rainbow width and height.
Choose XL or XXL
Very large decals require an open wall and more viewing distance.
They may overwhelm narrow rooms or disappear behind furniture if not carefully planned.
Add the Sun
Place the sun beside or above the rainbow.
Keep enough spacing so the two shapes remain distinct.
Add Polka Dots
Use dots to connect open areas.
Distribute the colors evenly and avoid filling every gap.
Conclusion
Use medium decals for compact displays, large sizes for focal walls, and XL or XXL designs only when the room has enough open wall and viewing distance. Add dots sparingly.
