Sizes and Proportions of All Lampshades

The shade is an essential part of the percentage of the overall light fixture. If the proportions are off, the fixture may seem too tall or too broad, or it may tip over too easily. The shade complements the base shape, and both together make a design statement in an area program. Choosing the proper lampshade starts with the size and ratio; style and design come after these components are determined.


Technically speaking, the lamp is your bulb. The fixture is made up of the base, which sits against the table surface, the stem and the socket. The shade fits onto the fixture with a metallic structure called a harp which attaches to the stem at the base of the socket.

Measure the Components

The height of this fixture is measured as the distance from the base of the base to the base of the socket. The width of a fixture is the broadest aspect of the base or stem. Shades are explained by their elevation dimension; for example, a 16-inch shade is 16 inches from the bottom edge to the top edge, measured up throughout the shade.The width of this shade is the broadest aspect of the shade. The slope of this shade is that the distance from the top edge down the side towards the base edge and decides the shade side angle. A cylindrical shade will have a length and slope of the same dimension. As the slope increases, the shade presumes a more conical shape, and also the diameter increases.

Great Proportions

Standard proportions suggest that the elevation of the shade needs to be between 60 and 80 percent of the fixture height into the base of the socket. By way of example, if the fixture measures 16 inches in height, a good shade height is 10 to 12 inches. Some fixtures, such as candlestick fixtures, rely upon the ratio of the shade being around one-quarter the overall elevation. By way of example, the shade on a candlestick fixture needs to be no longer than six inches tall if the total height of fixture and shade is 24 inches. All shades have to be long enough to cover the whole socket and expand at least one-half inch past the base of the socket. A floor fixture shade is in good ratio at about 36 percent of the stem length. The form of the base and stem will be the indicators of the form of the shade; curved stems work best with curved shades; straight-lined foundations work best with geometric shades.

Shade Diameter

Color diameter isĀ in good proportion to the base and stem if the shade is at least one-half inch wider than the broadest aspect of the stem — even though shades are often two inches wider or more. By way of example, if the base width is six inches, then the shade shouldn’t be greater than six and half dozen inches . This guidelineĀ best suits conventional shades on conventional foundations. Contemporary or modern fixtures may support shades much wider than this principle. The pitch and length of contemporary or modern shades may also be longer.

How to Choose a Lamp Shade Size

A lamp serves two purposes in your home. Its gives light that adds ambience to a room and makes the space immediately surrounding the lamp much more usable. The lamp also serves as a sculptural object that accentuates your decor even if it is not lit. Think of the colour as the bridge between form and function. Select a shade that shows your lamp foundation’s contour and sends mild to where it is needed.

Assess the distance from the foundation of lamp to the stem in case your lamp has one bulb socket. The stem is the portion of the lamp that sits immediately below the socket. Assess the distance between the base of this lamp as well as the socket cluster in case your lamp has a cluster of bulb sockets. Write down the measurement to bring with you when you shop for the colour.

Measure and write down the clearance your lamp comes with from furniture and walls so you can buy a shade that is suitable for the space.

Note the lamp harp’s style. The harp is the cable section that supports the shade. The lamp shade must be harmonious with the harp.

Determine what wattage bulb you will need for the lamp so you can buy a shade that stays a secure distance from the bulb. Supply 40- and 60-watt bulbs 2 inches of clearance and 150-watt lights 4 inches of clearance.

Sketch the form of your own lamp base. The shade should have a similar form.

Bring your measurements, notes and sketch when you shop for a colour. Choose a choice of shades that have shapes like complementary to the contour of the lamp and that are compatible with your lamp’s harp.

Gauge the underside diameters of the shades. The shade you select should have a bottom diameter that’s within 2 inches of the height of the lamp base.

Put the ruler along the slope of this shade to measure the distance between the base and top borders. This measurement should be within 1/2 inch of the height of this lamp’s stem.

Choose a shade that’s the appropriate size for the lamp that fits the space where you’ll use it which allows a secure distance between shade and wax.
