How to Measure Return and Projection for Drapery Rods

drapery rod projection

Return and projection are two hardware measurements that have a direct impact on how drapery panels hang, block light, and maintain their pleat structure. Even perfectly constructed drapes can perform poorly if these two numbers are incorrect. This guide breaks down exactly how to measure return and projection like a professional workroom.

What Is Return?

The return is the distance from the front of the rod to the wall. This measurement determines how far the panel wraps back toward the wall so the side edge sits flush and eliminates light gaps.

A correct return creates a clean, tailored side profile and prevents the lining from showing.

Typical Return Measurements

  • Pinch pleat: 2.5"–3.5"
  • Goblet pleat: 3"–4"
  • Cartridge pleat: 2.5"–3.5"
  • Ripplefold: system controlled, not sewn

How to Measure Return

  1. Measure from the front face of the rod (or rings) to the wall.
  2. Subtract 1/4" to prevent the return hook from pushing forward.
  3. Add 1/4" if working with heavy lining or interlining for smoother wrapback.

What Is Projection?

The projection is the distance the bracket extends from the wall to the center of the rod. This space is crucial because it must accommodate the fabric, pleats, lining, and any trimming.

A shallow projection crushes pleats, while an oversized projection increases side light gaps.

Standard Bracket Projections

  • Single decorative rod: 3"–4"
  • Heavy-duty rod: 4"–6"
  • French return rod: fixed 3.5"–4"
  • Cafe rod: 2"–3"

How to Measure Projection

  1. Measure from the wall to the center of the rod.
  2. Add fabric allowance:
    • Sheers: +0"
    • Standard lining: +0.25–0.5"
    • Blackout or velvet: +0.5–1"
  3. Confirm stackback clearance if the drapery will open fully.

Return vs. Projection

These two measurements must be compatible. As a rule of thumb: Return = Projection – 0.25" to 0.5". Incorrect pairing results in side gaps or crushed pleats.

Professional Tips

  • Always measure hardware after installation.
  • Increase projection for thick or interlined drapery.
  • French return rods produce the cleanest, light-tight return for blackout applications.
  • Check that pleats clear any window molding when stacking back.

Correct return and projection measurements are the foundation of professional drapery installation. When sized properly, they ensure clean lines, crisp pleats, and excellent light control.
