The Ultimate Guide to Dining Chair Size, Height & Width

Choosing the right dining-chair size is the quickest way to make your table feel welcoming and comfortable. Seat height determines leg-room, width sets each place-setting’s elbow space, and overall proportions control how roomy—or cramped—your dining area looks. Get these measurements right and every breakfast, birthday and Sunday roast feels effortless.

In this guide we’ll walk through the sweet-spot dimensions for standard, counter- and bar-height tables; show you a one-minute formula for calculating how many chairs fit; and share insider tips for mismatching styles without cluttering the room. Skim the cheat-sheet below or dive deeper for all the details.

Why Dining Chair Size Matters

The correct size dining chairs can really make a difference to the layout of your home. It not only ensures your dining room looks the part, but it also plays a role in the number of people you can entertain and whether they can sit comfortably. Ultimately, choosing the right size dining chairs affects:

• The look and feel of the room
• How many people your table comfortably fits
• Room layout opportunities 

On an even more practical note, the height and width of your chairs need to be suitable for your dining table, ensuring the chairs fit underneath it, and that enough of them can be placed around the table. It's important to measure your table beforehand and work out if your chosen chairs will suit your vision and your family size.

Top Tip: some people also mark out on the floor using masking tape so you can easily visualise how your new dining chairs will fit the space.

Ideal Dining Chair Seat Height

The first step in ensuring you get the perfect size dining chairs is understanding what the right height chair is for you. Firstly, you need to make sure that your chairs are low enough to slide under the dining table. This goes without saying, but it’s no use buying a set of high bar chairs for a low table! 

Ideally, the backrests will be slightly higher than the table and the seat itself significantly lower. Backrests should ideally reach the mid to upper back of someone who’s seated at the chair for optimal comfort. The seat height should be significantly lower than the table, ensuring your legs fit underneath the table comfortably.

The average height for a dining table is about 30 in / 76 cm, so dining chairs generally need to be around 18 in / 46 cm high. There should be around 12 in / 30cm between the tabletop and the seat. If you follow this rule of thumb, it's likely that you'll find the perfect height!

Choosing the Right Chair Width

Next, it’s important to find the perfect width to ensure you can sit comfortably and enough chairs can fit under the table. Most dining chairs come in widths between 16 - 20 in / 40-50 cm, however, the exact width will depend on the style of the chair. You will find the full dimensions including width, depth and height of all of our dining chairs for sale in the individual product description. This is especially important to note if you’re planning to style your room with mismatched dining chairs.

From an aesthetic perspective, the size of the chairs in relation to the dining table and the room itself can affect the perception of space. Overly large or small chairs may make the room feel cramped or empty, so it's essential to consider proportions.

Ideal Space Between Dining Chairs

It’s important to keep in mind that you need enough space between the chairs to ensure people can be seated comfortably. If you have a small or medium-sized table, then opting for a smaller chair will help you fit enough chairs around the table, as well as provide some much-needed room for your arms. Larger dining tables can more easily fit dining chairs with arms or wider chairs.

In general, it’s advised that you leave roughly 8-10 in / 20-25cm between chairs to ensure they’re not placed too close together. This will give your guests a comfortable amount of room to eat and manoeuvre.

How to Work Out How Many Chairs Fit

In short, the amount of chairs that you require varies depending on the size of your dining table. An easy way to work out how many people you can comfortably fit around your table is to simply take the external width of your chosen chair and add 8-10 inches. Then measure your table length and divide it by this number to give you the quantity of chairs you can fit on each side.

Ideal Space Behind Chairs

Allow at least 36 in / 91cm between your dining chairs and the wall, or any other furniture for that matter. This will give enough room for people to walk past, and to comfortably pull the chairs out. If you have a bit more room than average, 48 in / 121 cm is preferred as this will allow ample room for people to sit down and manoeuvre around the chairs. 

Ready to Choose Your Perfect Dining Chairs?

Finding the right dining chair size is important so you can seat enough people at the table and ensure that everyone sits comfortably. As long as there’s a minimum of 12 In / 30cm between the table top and the seat, the height of the chair allows people to sit comfortably. Additionally, if you can fit enough chairs around the table when you leave 8-10 in / 20-25cm of space between them, you have found the perfect dining chair size!
