Yes, IKEA Christmas decor adapts well to both small and large spaces by scaling decorative elements and selecting appropriate color combinations. In small rooms, focus on fewer focal zones with cozy lighting and scaled accessories. Larger spaces benefit from repeated motifs across multiple zones and layered light sources for warmth. The flexible more-is-more Scandi style blends bold checks, bows, and playful lighting to create festive, family-friendly atmospheres everywhere.
