Lampshade Sizing: The Love Frankie Guide

What size lampshade do I need?

It’s one of the questions we get asked most at Love Frankie HQ, and with good reason. Lampshade sizing can feel like a bit of a dark art when you’re staring at measurements online trying to imagine whether a 30cm shade is going to look perfectly proportioned or like a tiny hat perched on top of your lamp.

The good news is there are some simple tricks that make choosing the right size much easier.

This guide focuses mainly on drum lampshades, taking you through how to choose the right size for a ceiling pendant, floor lamp or table lamp, how to measure a lampshade properly and how to visualise the size before you order.

And remember: these are guidelines, not laws. Sometimes an oversized lampshade is exactly the point.

How Are Lampshades Measured?

Before we start, it helps to understand what all those measurements actually mean.

For a drum lampshade, you'll usually need two measurements:

DIAMETER: the width straight across the shade.

HEIGHT: the measurement from the top edge of the shade to the bottom edge.

At Love Frankie, our drum lampshade dimensions are shown as:

DIAMETER × HEIGHT

So a 40cm × 25cm lampshade measures 40cm across and 25cm high.

If you're replacing an existing shade that already looks beautifully proportioned on your lamp, measuring its diameter and height is often the easiest place to start.

What Size Lampshade Do I Need for a Ceiling Pendant?

Choosing a lampshade for a ceiling pendant is slightly different from choosing one for a lamp base.

There isn't a lamp underneath it to give you an obvious sense of proportion, so instead you need to look at the room around it.

Think about the size of the room, the height of the ceiling, where the pendant hangs, whether people need to walk underneath it and, importantly, how much of a statement you want your shade to make.

A small lampshade can disappear into a large room, while an enormous deep shade in a compact hallway can feel as though the ceiling is slowly descending upon you.

Ceiling Lampshade Size Guide:

 

These aren't hard and fast rules. They're simply a useful place to begin.

What Size Lampshade for a Bedroom Ceiling?

For most bedrooms, we'd start somewhere around 30-50cm in diameter, depending on the size of the room.

In a small bedroom, a 30-35cm drum can provide plenty of impact without dominating the space.

For an average or larger bedroom, we'd usually start around 40-50cm. If you've got a big room or high ceilings, don't be frightened of going larger.

Also think about where the pendant hangs. If it's directly over the bed, you can often afford to go bigger or deeper because nobody needs to walk underneath it.

What Size Lampshade for a Living Room Ceiling?

Living rooms can usually handle a little more lampshade.

For an average living room, we'd generally start around 40-50cm in diameter.

In a larger room, a 50-60cm shade often feels more proportionate, while big spaces and high ceilings can comfortably take a 60-70cm statement shade.

This is one of the most common sizing wobbles: a shade sounds enormous when you read the dimensions online, only to look surprisingly modest once it's hanging in the middle of a room.

Which brings us neatly to...

Don't Be Scared of Going Big

One thing we've learned after years of making lampshades? People are often much braver with colour than they are with size.

A 50cm or 60cm shade can sound enormous when you're looking at the measurements on a screen, but once it's hanging from the ceiling in a full-sized room, it can feel surprisingly well proportioned.

In larger rooms, a generous shade gives the light enough presence to hold its own against furniture, artwork and everything else going on around it. Go too small and even a beautiful lampshade can simply disappear into the ceiling.

And remember, your ceiling light doesn't only have to earn its keep when it's switched on.

We all know nobody actually wants the Big Light on anyway. 😉

Think of a large ceiling lampshade as part of the room itself. Go for fabulous colour, pattern, texture, fringing or a metallic lining and it becomes a dramatic statement piece even when the light is off.

Then, on those rare occasions someone is brave enough to switch on The Big Light, a gold or copper lining gives you that gorgeous warm glow from underneath.

If you've got the space, don't be afraid to size up.

What Size Lampshade for a Low Ceiling?

If your ceiling is low, think wide rather than deep.

A large-diameter shallow drum gives you the scale and drama of a bigger lampshade without hanging too far down into the room.

For example, a 60cm diameter × 20cm high drum will feel very different from a deeper 60cm x 30cm high shade.

You still get plenty of lampshade, just with less chance of your tallest house guest wearing it as a hat.

What Size Pendant Shade Over a Dining Table?

This is where you can have some fun.

Because nobody needs to walk directly underneath a pendant hanging over a dining table, you have much more freedom with both width and depth.

A larger statement shade can help anchor the dining area and make the lighting feel deliberately connected to the table beneath it.

Look at the proportions of your table rather than just the whole room. You want the shade to have presence without blocking everyone's view of each other over dinner.

What Size Lampshade Do I Need for a Floor Lamp?

Floor lamps generally need a larger lampshade than table lamps.

Stick a tiny shade on a tall floor lamp and the whole thing can start looking a little pin-headed.

A useful starting point is the rule of thirds.

Measure your floor lamp from the floor to the bottom of the bulb holder and divide that measurement by approximately three.

So:

140cm floor lamp ÷ 3 = around 47cm

We'd therefore start by looking at a 45–50cm diameter lampshade.

It's a guideline rather than a mathematical commandment, but it's a very useful starting point.

Floor Lampshade Size Guide

As a general guide:

35-40cm: smaller or particularly slender floor lamps
40-45cm: a useful middle ground for many standard lamps
45-50cm: larger floor lamps and bases with more visual weight
50cm+: substantial bases or when you deliberately want an oversized statement

Don't Forget Where Your Floor Lamp Is Going

A shade can look perfectly proportioned on the lamp and still be completely wrong for the space around it.

Is your floor lamp squeezed between a sofa and a wall? Sitting beside an armchair? Tucked into a corner? Close to a doorway?

Remember that a 50cm diameter drum really is 50cm wide.

Check you've actually got the clearance before going gloriously enormous.

What Size Lampshade Do I Need for a Table Lamp?

For a table lamp, the trick is getting the proportions between the lamp base and the lampshade feeling balanced.

Too small and the shade can look perched on top.

Too large and it can completely overwhelm the base.

The Table Lamp Rule of Thumb

Measure the height of your lamp base from the bottom of the base to the bottom of the bulb holder.

As a starting point, look for a lampshade with a diameter roughly similar to the height of your lamp base.

So:

30cm high lamp base → start with a 30cm diameter shade

Then look at the actual shape of your lamp.

If the base is particularly wide, chunky or curvaceous, you may prefer to go up to a 35cm shade.

If the base is very slim and delicate, you might prefer a 25cm shade.

The numbers get you into the right neighbourhood. Your eyes get the final vote.

Table Lampshade Size Guide

As a rough starting point:

20-25cm diameter: very small or dinky lamps
25-30cm diameter: bedside lamps and smaller table lamps
30-40cm diameter: medium table lamps
40cm+ diameter: large statement table lamps and substantial bases

Don't Forget the Table

This sounds ridiculously obvious until you've done it.

Check the width of the bedside table, console or side table your lamp is actually sitting on.

Your new shade might look magnificent on the lamp but become significantly less magnificent if you whack it every morning reaching for your cup of tea.

Remember, this is a starting point rather than a set of rules.

The proportions of your lamp, the size of your room and, frankly, how much lampshade you fancy all matter too.

How to Visualise Your Lampshade Size Before You Buy

We could suggest some sophisticated interior-design technology here.

Instead, we're going to suggest cardboard.

Because it works.

The Cardboard Trick

For a ceiling pendant, cut a circle of cardboard roughly the same diameter as the lampshade you're considering.

Get someone to hold it at approximately the height your shade will hang, then stand back and look at it from different points around the room.

Considering 40cm and 50cm? Cut both.

It's astonishing how quickly you'll realise which one feels right once you can actually see the scale in your room.

For a table or floor lamp, cut a rectangle using the approximate width and height of the shade you're considering and hold it above your lamp base.

Painter's tape, newspaper or an old cardboard box all work.

We're assessing proportions, not entering you for the Turner Prize.

What About Lampshade Shape?

Everything above is primarily aimed at choosing the right size drum lampshade, where the top and bottom of the shade have the same diameter.

But sometimes the problem isn't the size. It's the shape.

A tapered cone shade can look completely different on the same lamp base. A French drum gives you a gentler taper. A tall tube shade creates drama through height rather than width.

Then there are gathered and vintage-style soft shades, scalloped edges and fringe, where the overall silhouette changes the proportions completely.

So if you've measured everything correctly and a drum shade still doesn't quite look right, don't automatically go bigger or smaller.

You might simply need a different shape.

We've tackled all these questions in our Ultimate Guide to Choosing the Right Lampshade Shape, covering drums, cones, tubes, French drums, gathered and vintage-style shades.

Does Lampshade Fabric or Lining Make a Difference?

Not necessarily to the size you need, but it makes a huge difference to how the finished shade looks and how it lights your room.

Light-coloured fabrics can allow more light to glow through the sides of the shade, while darker fabrics create a moodier effect.

Metallic linings such as gold and copper reflect light beautifully from the top and bottom of the shade while creating a much more dramatic glow.

So once you've cracked the size, think about what you actually want your light to do.

Useful bedside light?

Soft ambient glow?

Or an enormous gold-lined leopard-print beacon of joy?

All perfectly legitimate lighting strategies.

Lampshade Size FAQs: Your Questions Answered

Lampshade Size FAQs: Your Questions Answered

Question	Quick answer
How big should a lampshade be?	It depends where it's going. For a table lamp, start with a shade diameter roughly similar to the height of the lamp base. For a floor lamp, divide the lamp height by around three. For a ceiling pendant, consider the size and ceiling height of the room.
How do I know what size lampshade to get?	If you're replacing a shade you already like, measure its diameter and height. Starting from scratch? Use your lamp base or room size as a guide, then try our cardboard trick to visualise the size before ordering.
How do you measure a drum lampshade?	Measure the diameter straight across the shade, then the vertical height from top edge to bottom edge. Love Frankie drum shades are listed as DIAMETER × HEIGHT.
Do you measure the top or bottom of a lampshade?	For a standard drum lampshade, either, as the top and bottom diameters are the same. For tapered shades such as cones and French drums, measure both the top and bottom diameters.
Are all lampshades the same size?	Definitely not. Lampshades come in different diameters, heights and proportions. Two 40cm shades can look completely different if one is shallow and the other is tall.
What size lampshade should I choose for a table lamp?	Measure from the bottom of the lamp base to the bottom of the bulb holder. A shade with a diameter roughly similar to that measurement is a useful starting point, then adjust for the width and shape of the base.
What size lampshade should I choose for a floor lamp?	40–50cm diameter is often a good starting point. Alternatively, measure the lamp to the bottom of the bulb holder and divide that measurement by around three to estimate a starting shade diameter.
What size lampshade should I choose for a bedroom ceiling?	30–50cm diameter works as a useful starting range for most bedrooms. Smaller bedrooms may suit 30–35cm, while average or larger rooms can often carry 40–50cm or more.
What size lampshade should I choose for a living room ceiling?	Around 40–60cm diameter is a useful starting point for many living rooms. Larger rooms or high ceilings can usually handle considerably bigger statement shades.
What size lampshade works with a low ceiling?	Look for a wide, shallow lampshade rather than a tall shade. You can still go big on diameter without sacrificing lots of headroom. Something around 60cm wide × 20cm high, for example, can make a statement without a huge drop.
What size lampshade should I hang over a dining table?	You can usually go larger and hang lower over a dining table because nobody needs to walk underneath it. Wide, shallow shades work particularly well and help create a defined pool of light over the table.
Can a lampshade be too big?	Technically, yes. But people are often more cautious with lampshade size than they need to be. A larger shade usually looks better when its proportions make sense with the lamp base, furniture or room around it.
Can a lampshade be too small?	Absolutely. A tiny shade on a substantial table or floor lamp can make the whole thing look top-heavy or slightly pin-headed. If you're between two sizes, it's often worth mocking up the larger one before deciding.
Should a lampshade be wider than the lamp base?	It can be. There's no rule saying a shade must sit within the width of the base. The overall proportions matter more than matching the exact width, particularly with narrow or unusually shaped lamp bases.
How can I check a lampshade size before ordering?	Try the Love Frankie cardboard trick. Cut a cardboard circle to test a ceiling shade diameter, or a rectangle matching the width and height of a table or floor shade. Hold it in position, stand back and see how it feels in the room. No artistic ability required.

Still Not Sure What Size Lampshade You Need?

Send us a photo.

Actually, don't physically send us your lamp. That would make for an interesting day at Love Frankie HQ.

Send us:

• a photo of your lamp base
• its height and widest measurement
• a photo showing where it sits in the room, if possible

We'll happily point you towards the sizes we'd consider.

And if you're choosing your fabric at the same time, you can order samples to see the colours and textures at home before committing to your finished shade.

Because sometimes you can measure, calculate and stare at cardboard circles for hours and still just want another human to say:

“Yep. I'd put a 40cm on that.”

We're very happy to be that human.
