How Deep Should a Bedside Table Be? Dimensions Guide

The ideal depth for a bedside table is between 30 cm and 45 cm, depending on the available space next to the bed and the required storage capacity.

When planning a bedroom, the distance between the bed frame and the wall or the neighbouring piece of furniture determines which dimension makes sense. A bedside table that is too deep obstructs walkways or wardrobe doors, whilst one that is too shallow does not provide enough surface area for a reading lamp, alarm clock, and book. This guide explains which dimensions suit different room layouts and what DIY enthusiasts need to consider during assembly.

Standard Dimensions: How Deep Is a Classic Bedside Table?

Bedside tables often take their cue from small chests of drawers when it comes to dimensions. The choice of depth largely determines which type of fittings can fit inside and how much usable surface area is available on the top panel. When planning or assembling bedside tables and nightstands, you will usually encounter the following standard depths:

• 30 cm depth: This is the absolute minimum dimension for traditional bedroom furniture. A chest of drawers 30 cm deep works brilliantly as a bedside table in compact rooms. The top surface provides space for a book and a smartphone. Drawers of this depth usually use a short roller runner.
• 35 cm depth: A solid compromise. A chest of drawers 35 cm deep offers sufficient stability for a larger table lamp. The drawers are deep enough for charging cables and spectacle cases.
• 40 cm depth: The comfort zone starts at this dimension. A chest of drawers 40 cm deep allows for the installation of a ball bearing runner as a full extension slide. The drawer can be pulled out 100%, making access to the rear section much easier.
• 45 cm depth: If the room allows it, a chest of drawers 45 cm deep provides maximum storage space. Thicker books, tablets, or water bottles can easily be accommodated here.

Materials and Assembly: What DIY Enthusiasts Need to Know

Assembling a bedside table works like a well-organised toolbox – every component has its designated place and interlocks logically with the next. Most flat-pack units are made of chipboard or MDF coated with a scratch-resistant decor (such as melamine resin).

For the carcass, cam lock fittings and wooden dowels are generally used. This combination ensures right-angled stability without screw heads showing on the outer surfaces.

Tools required for assembly:

• Cross-head screwdriver (usually size PZ2 for chipboard screws)
• Rubber mallet (for gently knocking in dowels)
• Spirit level (for alignment if the bedside table has adjustable plinth feet)
• Tape measure or folding rule (to measure the exact distance to the bed)

Space Solutions: Coordinating Bedside Tables with Adjacent Furniture

In compact bedrooms, a bedside table rarely stands in isolation. It often sits right next to a run of wardrobes. In this scenario, furniture depths must be coordinated with one another to achieve a flush appearance or prevent doors from colliding.

If there is a wardrobe 50 cm deep next to the bed, the bedside table should ideally have a depth of 40 cm to 45 cm. This creates a neat step-back. Alongside a narrower wardrobe 40 cm deep, a bedside table with a depth of 30 cm or 35 cm is recommended.

Repurposing Furniture for Extremely Narrow Alcoves

Sometimes, only 20 cm to 25 cm of space remains between the bed edge and the wall. Standard bedside tables will not fit here. Experienced DIYers often turn to furniture designed for other living areas in these cases. A bathroom cabinet 25 cm deep or even a shoe cabinet 20 cm deep can serve as a minimalist bedside surface. Wall mounting is essential here, as very shallow units tend to tip forward when a flap or door is opened.

Planning Checklist

Before beginning assembly or drilling holes for a floating bedside table, check the following dimensions:

1. Mattress height: The top edge of the bedside table should ideally be level with the mattress. For continental beds or box springs, taller units (50 cm to 60 cm) are often required.
2. Clearance for wardrobe doors: If the adjacent wardrobe has hinged doors with a corner stop (full overlay), check the door swing path. The bedside table must not block the wardrobe door from opening.
3. Under-bed storage drawers: If the bed has pull-out drawers at the side, the bedside table must either be wall-mounted or positioned far enough towards the headboard.

Frequently Asked Questions About Bedside Table Dimensions (FAQ)

Can I use a standard chest of drawers as a bedside table? Yes. As long as the height suits the bed, narrow chests of drawers work wonderfully. A standard chest of drawers with a depth of 30 cm or 35 cm often offers more drawers than a conventional nightstand and makes better use of vertical space.

How much space should be left between the bed and the bedside table? A gap of 5 cm to 10 cm is advisable. This allows the bedsheet to be fitted around the corners of the mattress easily without trapping your hands against the furniture.

What can I do if there is very little space next to the bed? When even 30 cm is too deep, wall-mounted floating shelves or repurposed hallway and bathroom cabinets can help. A bathroom cabinet 20 cm deep provides enclosed storage with a minimal footprint and often integrates seamlessly into modern bedrooms.
