Measuring a drum lampshade is straightforward, focusing on its key dimensions. Based on the provided information, you need to measure the top width, the bottom width, and the shade height.
Essential Measurements for a Drum Lampshade
According to tips for measuring lampshades, specifically mentioning drum and tapered drum styles, the crucial measurements are:
- Top Width: The diameter across the top opening of the lampshade.
- Bottom Width: The diameter across the bottom opening of the lampshade.
- Shade Height: The vertical distance from the top edge to the bottom edge of the lampshade.
For a true "drum" lampshade, the top width and bottom width will be identical, as the sides are straight and parallel.
Why the Vertical Slant Isn't Needed
The reference explicitly states that the "vertical slant... isn't a factor on drum or tapered drum Shades only on Shades that have a severe pitch." Since a drum shade has straight, vertical sides, there is no slant to measure.
Quick Reference Table
Here's a simple breakdown of what to measure:
| Measurement | Description | Relevance for Drum Shades |
|---|---|---|
| Top Width | Diameter at the top | Yes |
| Bottom Width | Diameter at the bottom | Yes |
| Vertical Slant | Angle/slope of the side | No |
| Shade Height | Vertical distance from top to bottom straight up | Yes |
Steps for Accurate Measurement
To get the most accurate measurements for your drum lampshade:
- Use a Ruler or Measuring Tape: Ensure it's long enough to span the diameter or height easily.
- Measure the Top Width: Place the ruler across the very top opening, measuring from one edge directly across to the opposite edge.
- Measure the Bottom Width: Place the ruler across the very bottom opening, measuring from one edge directly across to the opposite edge. (For a drum shade, this should match the top width).
- Measure the Shade Height: Stand the lampshade upright on a flat surface. Measure the vertical distance from the top rim straight down to the bottom rim.
Using these measurements helps ensure you find a replacement shade or understand the dimensions of your current one.
