Vintage Lamp Shades: Finding the Right Replacement Shade

Measure your old shade’s top width, bottom width, slant and height, and note how it attaches: a spider fitter on a harp, an UNO ring or a clip-on. Then size the replacement to the lamp. Lamps Plus suggests a shade about a third of the lamp’s height and twice the width of its base.

How do you measure an old lamp shade?

Measure an old lamp shade in four places, in inches, on the shade you are replacing. If the size looked right before, a replacement within about half an inch of each will look right again.

Write the numbers down in the order top, bottom, slant, so a “6 x 12 x 9” note means 6 inches across the top, 12 across the bottom and 9 down the side. Check which order a listing uses before you compare.

For a lamp that has lost its shade, start from the lamp instead.

What size shade suits the lamp?

Lamps Plus gives two starting rules, and both are worth a quick check with a tape measure:

• Height: the shade should be about one third of the lamp’s overall height, “give or take.”
• Width: the shade should be about twice the width of the lamp base. Unusual base shapes shift this, so treat it as a first guess.

Then check the shade on the lamp. A separate Lamps Plus guide says the shade is at the right height “when just a half inch of the lamp neck” is showing, the part of the base just below the socket. If the socket’s hardware shows below the shade’s bottom edge, the shade is too small or sits too high.

Which shade shape fits a vintage base?

A vintage base sets the shade’s shape. Lamps Plus suggests that a shade’s shape should follow the contour of the lamp: curved shades for curved bases, straight-sided shades for straight bases, square shades for square lamps. A cone shape can make a bottom-heavy base look lighter.

Two more pairings help with older lamps:

• Plain base, fancy shade; fancy base, plain shade. A richly decorated base reads best under a simple shade, and a plain one can carry a pleated or trimmed shade.
• Fabric changes the mood. Silk reads as formal; linen and parchment look more casual, by the same guide.

Glass is a different job. A leaded or deco glass shade has to suit the base or holder it sits on, so these fabric shade rules are only a rough guide; see the guides to Tiffany lamp shades and art deco lamp shades.

Will the new shade fit your lamp’s fitter?

The fitter is the wire part of the shade that meets the lamp, and Lamps Plus is blunt that fitters “are not interchangeable.” The spider is the most common fitter on table and floor lamp shades. It sits on top of a harp and is held by a finial. UNO fitters sit on a matching socket and are used mainly on European lamps. Clip-on shades grip the bulb, and Lamps Plus advises against higher-wattage bulbs under them because the shade sits so close.

The rewiring guide compares the three fitters in a table, with how each one holds the shade.

Height is the easy fix. Grand Brass describes harps as a removable frame “available in multiple heights”, so if a new spider shade sits too low or too high, change the harp rather than the shade. Lamps Plus adds that shades up to 14 inches high typically have a half inch fitter drop, the distance the fitter sits below the shade’s top edge; taller shades usually drop more.

How do you clean a vintage fabric or paper shade?

Clean a vintage shade off the lamp, and match the method to the material. Lamps Plus suggests:

• Fabric or silk: a lint roller, a soft brush, a vacuum with a brush attachment, or a dry cloth.
• Paper or parchment: a dry microfiber cloth, wearing gloves so hand oils do not mark it.
• Plastic: a soft cloth with warm water and mild dish detergent, then air dry.

Go gently on a shade that is decades old. If the fabric has split or the paper has gone brittle, a replacement shade is the safer choice, and the old frame can stay with the lamp as a record of its original size.

Should you keep the lamp’s old shade?

Keep it if it is original and sound, even if you use a new one day to day. An original shade adds to a lamp’s story, and its size tells you what the maker intended. Our identification guide explains how to read the lamp’s marks, and the brass cleaning guide covers the base while the shade is off.
