When choosing a lamp for our home, we first choose the pattern, fabrics and shape of the lampshade. But then we are often faced with a huge dilemma: how big a lampshade should we buy? This seemingly simple question is much more complex than we might think, as the right size is crucial for the proportions of the space, the diffusion of light and the overall effect. That is why in this article we have prepared a practical guide to choosing the perfect size. We will introduce some aspects that are worth considering to ensure that we choose a lampshade that is not only beautiful, but also fits perfectly into our home and provides the right light source for the function of the given room.
Why is the size of the lampshade important?
The lampshade is not only a design element, but also plays a functional role. If it is too big, it can overwhelm the surrounding furniture, if it is too small, it can get lost in the space or not provide enough light. The right size lampshade:
- Harmonizes with the lamp base
- Is proportional to the size of the room
- Diffuses light optimally
- Highlights our style
Let's look at the details to make sure we choose the right size lampshade.
What size lamp base do we have that we want to place the lampshade on?
One of the most important starting points is what kind of lamp base the lampshade will be placed on. A general rule of thumb: the diameter of the ideal lampshade should be about ⅓-½ of the height of the lamp base. For example: if the lamp base is 60 cm high, the diameter of the lampshade is ideal between 30–40 cm. This ensures proportionality and prevents the lamp from becoming unstable. To this end, we can choose LAMPARiOMA Studio's lampshades in up to 21 different sizes. But if we still haven't found what we really want, we are happy to make what our dear customers dreamed of. If you are not sure what size lampshade to order, we are happy to help.

How big a room do we want to place the lampshade in?
To do this, we first need to know the size and function of the given room. After all, a different size lampshade is needed for a bedside table than for a reading corner in the living room. We will introduce some aspects that are worth considering. In a room with a small floor area or on a small table, we should place a narrower, lower lampshade, for example a version with a diameter of 20–30 cm. In a larger space or on a chest of drawers, a larger diameter and higher lampshade is needed. For example, one with a diameter of 35–40-45-50 cm. What is also worth considering in this case is that the size of the lampshade also visually affects the sense of space.
What is the type and purpose of the light source?
Many of us take this into account less when choosing a lampshade, although it is a very important aspect. Because there is a difference between a reading lamp, a floor lamp or a decorative table lamp. Transparent, lighter-colored, and larger lampshades let in more light, while darker, narrower shapes provide a more focused, intimate light.

How do we determine the right lampshade size?
If we already have an existing light fixture but want a new lampshade, simply measure the old lampshade. The most important thing is the diameter of the bottom and top, followed by the height. Then measure the height of the lamp base, which, as mentioned above, determines the size of the lampshade. Although the focus of this article is on the size of the lampshade, let's not forget its shape: You can choose a cylindrical, conical, oval, or square shape.
Summary – what size lampshade should I buy?
This depends on the size of the lamp base, the size of the room, and the desired lighting effect. Moreover, choosing a lampshade is not only a technical decision, but also a creative one.
