A 3ft 6 bed is wider than a standard UK single, so standard single bedding does not always fit correctly. Fitted sheets and mattress protectors are usually too narrow, while a standard single duvet may not give enough side coverage.

The best approach is to choose bedding made specifically for a Large Single / 3ft 6 mattress.

In this guide, we explain which fitted sheets, mattress protectors, duvets, duvet covers and other bedding are best suited to a 3ft 6 bed.


What Size Is a 3ft 6 Bed?

A 3ft 6 mattress is approximately 107cm wide.

Common sizes include:

  • 3ft 6 x 6ft 3in – approximately 107 x 190cm
  • 3ft 6 x 6ft 6in – approximately 107 x 200cm
  • 3ft 6 x 7ft – approximately 107 x 213cm

This bed size is commonly known as a Large Single and may also be described as a Three Quarter or Super Single, although exact dimensions can vary between manufacturers.

If you are unsure which size you have, see our Large Single Bed Size Guide.

What Fitted Sheet Fits a 3ft 6 Bed?

You should use a fitted sheet made for a mattress around 107cm wide.

A standard UK single fitted sheet is normally designed for a mattress around 90cm wide, so it is usually too narrow for a 3ft 6 bed.

It is also important to match the length and mattress depth. A 107 x 190cm sheet will not fit a 107 x 200cm mattress correctly, and a shallow sheet may pull away from the corners of a deeper mattress.

Our Large Single Fitted Sheets are available for several 3ft 6 mattress lengths and in different depth options.


Can I Use a Standard Single Sheet on a 3ft 6 Bed?

Usually not.

A standard single fitted sheet is around 17cm narrower than a typical 3ft 6 mattress. Even if you manage to stretch it over the corners, it is likely to pull loose or place too much strain on the fabric and elastic.

A correctly sized Large Single fitted sheet will give a much neater and more secure fit.


What Mattress Protector Fits a 3ft 6 Bed?

Mattress protectors should also match the actual mattress width, length and depth.

A standard single protector will normally be too narrow for a 107cm mattress, so look for a protector specifically designed for a Large Single bed.

Our Large Single Mattress Protectors include options for specialist 3ft 6 sizes.

You can choose between quilted protectors for everyday mattress protection and waterproof options where additional protection from spills or moisture is important.


What Size Duvet Fits a 3ft 6 Bed?

You can use a standard UK single duvet on a 3ft 6 bed, but it may look narrow and provide less overhang at the sides.

A Large Single duvet gives more generous coverage without being as wide as a standard double duvet.

Our Large Single Duvets measure approximately 152 x 220cm.

Compared with a typical 135 x 200cm standard single duvet, this gives you:

  • Extra width for better side coverage
  • Extra length for taller sleepers
  • A more balanced appearance on a 3ft 6 bed


    Can I Use a Double Duvet on a 3ft 6 Bed?

    Yes, but it will give considerably more overhang.

    Some sleepers like the extra coverage of a double duvet, but on a 3ft 6 bed it can feel bulky and may hang quite low at the sides.

    A Large Single duvet sits between a standard single and double, making it a useful middle option for wider single beds.

    What Size Duvet Cover Do I Need?

    The duvet cover should match the duvet itself rather than the mattress.

    If you choose a 152 x 220cm Large Single duvet, use a matching Large Single Duvet Cover.

    A standard single duvet cover will be too small, while a double duvet cover will contain too much loose fabric.


    What Flat Sheet Fits a 3ft 6 Bed?

    Flat sheets are more forgiving than fitted sheets because they are not shaped around the mattress corners.

    You can use a generously sized flat sheet as long as there is enough fabric to cover the mattress and tuck securely underneath.

    If you prefer a neater fit, choose a flat or semi-fitted sheet made specifically for a Large Single mattress.


    What Mattress Topper Fits a 3ft 6 Bed?

    A mattress topper should match the mattress width and length as closely as possible.

    A topper designed for a standard single will leave part of the mattress uncovered, while a Small Double topper may be too wide.

    Large Single toppers are available for specialist 3ft 6 mattress dimensions and can add comfort without compromising fit.


    What About 107 x 200cm Beds?

    A 107 x 200cm mattress is approximately 3ft 6 x 6ft 6 and is a common specialist Large Single size.

    It is also frequently used for adjustable and electric beds.

    If this is your mattress size, visit our dedicated 3ft 6 x 6ft 6 Bedding section for bedding matched specifically to 107 x 200cm beds.


    Does an Adjustable 3ft 6 Bed Need Different Bedding?

    The mattress dimensions remain the most important factor, but adjustable beds can benefit from bedding designed to stay secure while the bed changes position.

    Correctly fitted sheets and mattress protectors are particularly useful because loose bedding can move as the mattress profiles.

    Specialist options such as semi-fitted top sheets and easy-fit valances can also make an adjustable bed easier to dress.

    3ft 6 Bedding Checklist

    If you have a Large Single bed, your basic bedding setup could include:

    • A fitted sheet matched to the exact 107cm mattress size
    • A mattress protector matched to the same width, length and depth
    • A Large Single duvet for better coverage
    • A matching Large Single duvet cover
    • A topper in the correct mattress dimensions if required
    • Standard or king-size pillowcases depending on your pillow choice


      Measure Before You Order

      Because 3ft 6 beds can be made in different lengths, always measure the mattress before ordering.

      Check:

      1. Width – around 107cm for a typical Large Single
      2. Length – often 190cm, 200cm or around 213cm
      3. Depth – including any mattress topper that remains under the fitted sheet

      Using the exact measurements is more reliable than ordering from the bed name alone.


      What Bedding Fits a 3ft 6 Bed? FAQs

      What size sheet fits a 3ft 6 bed?

      A fitted sheet around 107cm wide is normally required. Match the sheet length and depth to the actual mattress as well.

      Will a standard single fitted sheet fit a 3ft 6 bed?

      Usually not. A standard single mattress is around 90cm wide, so the fitted sheet will normally be too narrow for a 107cm mattress.

      What duvet should I use on a 3ft 6 bed?

      A Large Single duvet around 152 x 220cm provides more side and foot coverage than a standard single duvet and works well on many 3ft 6 beds.

      Can I use a double duvet on a 3ft 6 bed?

      Yes, but it will provide more overhang and may feel bulky. A Large Single duvet offers a useful middle size between single and double.

      What mattress protector fits a 107cm bed?

      Choose a Large Single mattress protector designed for the correct 107cm width and matching mattress length.

      Is 3ft 6 the same as a Three Quarter bed?

      The terms are often used for similar beds, but dimensions are not always consistent. Always check the actual mattress measurements before buying bedding.
