How to Use Vertical Lines in Mid-Century Modern Design

Mid-century modern design is all about clean lines, functional beauty, and simplicity, but one often overlooked element in this timeless style is the use of vertical lines. These lines can add height, structure, and sophistication to a space, while staying true to the understated elegance of mid-century modern design.

I first discovered the power of vertical lines when redesigning a small, boxy living room. By incorporating vertical paneling and a floor-to-ceiling shelving unit, the space felt taller and more open without adding any actual square footage. Ever since, vertical lines have become one of my go-to tools for creating balance and drama in mid-century-inspired interiors.

In this guide, I’ll walk you through creative ways to use vertical lines in mid-century modern design, from wall treatments to furniture and decor.
