✅ How to Measure for Vertical Blind Slat/Vane Replacement

You do not need to measure the headrail for replacement slats—just the vanes themselves.

✅ 1. Measure the Length (Height)

If you still have an old vane

This is the easiest method.

1. Remove one existing slat from the headrail.
2. Lay it flat on a table.
3. Measure from the very top of the vane (full fabric length turnover edge to turnover edge)
   down to the very bottom.

✅ This is your exact replacement length.

⚠️ Important: Do not subtract anything. Vertical slats will be fabricated to the exact length measured.

If all vanes are missing

Inside‑mounted blinds

1. Measure from the underside of the headrail
2. Down to where you want the bottom of the vanes to hang
   (usually 1/2" above the floor or window sill)
3. Subtract 1/2 inch from that number

✅ This is the correct vane length.

Outside‑mounted blinds

1. Measure from the bottom of the headrail
2. To your desired bottom point
3. No subtraction needed—use the full measurement.
