Forty-eight inches is an awkward number until you understand what it is for. It is too tall to sit beside a sofa like a table lamp, and nowhere near tall enough to read as a floor sculpture. The 10A sits in the narrow band between those two jobs — 21 inches wide, 48 inches tall, a full sphere on a tripod — and that proportion decides everything about where it belongs.
Here is how to tell whether it fits your room before you buy it.
The number nobody quotes: height divided by width
Every floor lamp in this family is described by a diameter and a height, but the ratio between them is what you actually perceive. A shade twice as tall as it is wide reads as a column. A shade roughly as tall as it is wide reads as an object sitting on the floor. Same material, completely different presence.
Sort the whole range by that ratio and three groups appear:
| Model | Diameter | Height | H ÷ W | Character |
|---|---|---|---|---|
| 20N | 16.5 in (42 cm) | 23.6 in (60 cm) | 1.4 | Nearly a sphere on short legs |
| 9A | 17.3 in (44 cm) | 27.2 in (69 cm) | 1.6 | Seated-height glow |
| 10A | 21 in (53 cm) | 48 in (123 cm) | 2.3 | The widest of the tall |
| 13A | 19.7 in (50 cm) | 52.4 in (133 cm) | 2.7 | Column, slightly narrow |
| UF3-Q | 22 in (56 cm) | 57 in (145 cm) | 2.6 | Same idea, one size up |
| 11A | 15.7 in (40 cm) | 58 in (147 cm) | 3.7 | Tall and slim |
| 14A | 13 in (33 cm) | 64 in (162 cm) | 4.9 | Nearly a staff |
At 2.3, the 10A is the widest thing in the tall group. Below it you get spheres that hug the floor; above it you get columns that carve vertical space. That is the whole reason it photographs so differently depending on the room you put it in.
What 48 inches does at seated and standing eye level
The shade is a 21-inch sphere, so its centre sits roughly 37 in (94 cm) off the floor and its top edge lands at 48 in (123 cm). Put those numbers next to the ones every room already has:
| Reference | Typical height | Against the 10A |
|---|---|---|
| Sofa back | 30–36 in (76–91 cm) | The shade clears it by 12–18 in — the globe floats above the sofa line instead of hiding behind it. |
| Seated eye level | 42–46 in (107–117 cm) | The shade centre sits about 5–9 in below your eyeline. You look over the top of the glow, not into it. |
| Dining table surface | 30 in (76 cm) | The globe is well above the table, so it lights the room rather than the plates. |
| Standing eye level | 60–66 in (152–168 cm) | The whole lamp sits below your sightline — you read it as an object, not as a light source. |
That last row is the whole character of the lamp. At 48 inches the 10A never looks you in the eye while you are standing. It reads as furniture — a lit sphere at hip-and-a-half height — which is why it works in a corner or beside a console and feels wrong as a reading lamp.
Where it actually belongs
Beside a sofa, on the tall side. The globe clears a standard sofa back by more than a foot, so light rises into the room instead of being trapped behind upholstery. Keep 12–18 in (30–45 cm) of gap from the sofa arm so you are not looking through the shade when seated.
An empty corner that needs a vertical event. This is the 10A's best use. A corner with nothing in it reads as a hole; a 48-inch lit sphere reads as a decision. Keep it 8–12 in (20–30 cm) off both walls so the paper has air around it.
Beside a low console or sideboard. Because the sphere starts around 27 in off the floor, it pairs well with furniture 30 in tall or lower — the shade sits above the surface rather than colliding with it.
Not beside a reading chair. This is the honest part. A reading lamp needs its shade at 40–48 in with the light directed down onto a page. The 10A puts a 21-inch globe in your peripheral vision and throws light outward in every direction — pleasant in a corner, distracting over a book.
The three versions, and what the money buys
| Version | Price | What changes |
|---|---|---|
| Classic | $355 | Natural bamboo ribs with hidden connectors, washi with visible fibre. The version most rooms end up with. |
| Mastercraft | $530 | Hand-tied bamboo joinery throughout — every rib bound by hand rather than seated in a connector. Same silhouette, longer build, and the one that holds its shape for decades. |
| Machine-carved | $180 | A carved wood frame in place of bamboo. Entry price, different material story, and it comes in and out of stock — ask before you plan around it. |
The $175 gap between Classic and Mastercraft is not cosmetic. It is the difference between ribs seated in connectors and ribs tied by hand — which is exactly the part that decides whether the shade still sits circular in year ten. If you are buying this as a long-term piece, that is the line item to think about.
If the 10A is not quite right
Want the same idea, bigger: the UF3-Q is 22 in wide and 57 in tall — one step up in both directions, and the extra 9 inches of height changes how it reads in a tall room.
Want it narrower: the 13A is 19.7 in wide at 52.4 in tall. Nearly the same height, a slimmer globe, less visual weight against a wall.
Want it much lower: the 9A at 27.2 in total height is a seated-height glow — the shade lands near the seat of a chair rather than above it.
Want a column instead of a sphere: the 11A at 15.7 in wide and 58 in tall, or the 14A at 13 in wide and 64 in tall. These carve vertical lines; the 10A occupies volume.
Frequently asked
Is 48 inches tall enough for a floor lamp?
For ambient light, yes — the shade top sits just above a seated eyeline and well below a standing one, which is why it reads as furniture rather than a light fixture. For reading, no: a task lamp needs its shade at 40–48 in with light directed downward, not a 21-inch globe spreading light in all directions.
Will it fit in a small apartment?
The footprint is a tripod roughly 21 in across, so it needs about 2 ft (60 cm) of floor and 8–12 in (20–30 cm) of clearance from each wall to look right. In a room under 100 sq ft it can dominate — a 9A or 22N at 25–27 in tall usually sits better.
Is the $180 version the same lamp?
Same silhouette and dimensions, different frame material — carved wood instead of bamboo. It is a genuine third option rather than a cheaper build of the same thing, and it comes in and out of stock.
What bulb does it take?
A standard E26 base; a 5W warm LED is included. Stay with LED — incandescent heat yellows the paper and the globe traps that heat more than an open shade would.
Can the cord be shortened?
The 79 in (200 cm) cord has an in-line foot switch. Because the switch sits partway along, shortening it means losing the switch unless the cord is re-terminated — tell us the length you need when you order and we will build it that way.
Do you make other sizes?
Yes. We are a workshop, so a different diameter is a build instruction rather than a new product. Tell us the width and height your room needs. We are an independent studio, not affiliated with the Noguchi Museum.
