How tall should bedside table lamps be?

Most bedroom designers and lighting specifiers agree on a range of 55–70 cm for a bedside lamp's total height, measured from the base to the top of the shade. The practical reason is straightforward: when you sit up in bed against a pillow, your shoulder sits roughly 60–65 cm above the mattress surface. A lamp that places the bottom of its shade at or just above that point casts light onto your book or phone without shining directly into your eyes.

The bedside table itself factors in. A standard UK bedside table stands around 50–55 cm tall, so a lamp of 55–65 cm sits comfortably on it without the shade towering above head height or the bulb disappearing below the table edge.

Among the many table lamps designed specifically for bedroom use, adjustable-arm styles offer the most flexibility because you can reposition the head rather than relying solely on overall height. Fixed-base lamps with a drum or empire shade work well when the proportions are chosen carefully before purchase.

If your bedside table is unusually low — under 45 cm — lean towards the taller end of the range. If it is a tall nightstand at 60 cm or more, a lamp of 50–55 cm total height may be sufficient, because the combined height still places the shade at the right position relative to your eye line.

Shade dimensions matter as much as the lamp's total height. A deep empire shade — one that drops 25 cm or more from its top ring to its lower edge — can block useful light even on a lamp that measures 65 cm overall, because the bulb sits well inside the shade cavity. In that situation, you may need to choose a lamp at the taller end of the 55–70 cm range, or switch to a shallower drum shade that lets light escape more freely downward and to the sides.

Shade width also plays a role. A very wide shade on a short lamp will project light outward across the bed rather than downward onto a book, which suits ambient lighting but not focused reading. For reading, a shade no wider than 30–35 cm at the base keeps the beam more directed.

When assessing a lamp in a showroom or online, check the shade dimensions listed separately from the overall height. The useful measurement is the distance from the floor (or table surface) to the lower rim of the shade — aim for that to land between 100 and 115 cm from the floor, which typically corresponds to shoulder height for most adults sitting up in a standard UK double or king bed.

Practically, if you are ordering online and cannot measure in person, filter by lamps with a shade drop of 15–20 cm and a total height of 60–65 cm. That combination reliably hits the target zone across most bedside table heights.

The 55–70 cm guideline is calibrated for reading comfort. If you use your bedside lamp purely for atmosphere — winding down before sleep rather than reading — you have more freedom. A shorter lamp of 45–55 cm, or even a low table lamp placed on a higher shelf, can create a warm pool of light at a lower level that feels more restful and less clinical.

Dimmer compatibility becomes especially relevant for ambient use. A lamp fitted with a warm-white LED at 2700 K, dimmed to around 10–20% output, signals to the body that it is time to sleep. Research cited by the Energy Saving Trust notes that switching to efficient, dimmable LEDs in the bedroom can reduce energy use without sacrificing the quality of light needed for winding down.

For households where one partner reads and the other sleeps, an adjustable-arm lamp is the practical solution. It can be positioned high and directed for reading, then swung flat against the wall to minimise spill. In that scenario, the base height matters less than the arm's reach and the lamp's directional control.

If you have a double bedside setup, match the lamp heights on both sides even if the lamps are different models. Mismatched heights create visual imbalance and uneven light across the bed, which is noticeable even when only one lamp is switched on.

Height and position both affect safety, not just aesthetics. A lamp placed too close to a curtain or fabric headboard creates a fire risk if the bulb runs hot. Halogen bulbs are the main concern here — a standard GU10 halogen can reach surface temperatures above 200 °C. Modern LED equivalents run far cooler, but it is still good practice to keep any lamp at least 30 cm from soft furnishings.

Flex management is the other common hazard. A lamp positioned at the back of a bedside table often has its cable trailing behind the table or looped under a leg. Pinched or kinked cables degrade over time and can cause faults. Route the cable cleanly and avoid running it under rugs or behind furniture where it cannot be inspected.

If you are adding a new socket or relocating an existing one to better position a bedside lamp, the work must be carried out by a qualified electrician and notified to your local authority under Part P of the Building Regulations. The Electrical Safety First guidance on Electrical Installation Condition Reports explains when a formal inspection is required — particularly relevant in older properties where the wiring may not meet current standards.

For most people, the simplest safety step is to choose a lamp with a good-quality UK plug, a cable long enough to reach the socket without stretching, and an LED bulb that runs cool from the outset.
