Measuring for Blinds has never been easier. The measuring tips found here will help you get the perfect measurements for your new blinds. Download the free measuring sheet to help you in your measuring.

A Few Tips before Starting
  • Always use a metal measuring tape
  • Take measurements in millimetres (mm)
  • Never round to the nearest millimetre
  • Measure from left side to right side of window
  • Mark down your WIDTH measurement first then followed by your HEIGHT (W x H)
  • Measure each window individually (even if appear the same, as there may be minor differences)
  • Don’t based measurements off house plans - Take real measurements
  • When installing INSIDE the window, provide opening sizes only
  • When installing OUTSIDE the window, provide exact blind sizes
  • Always measure twice to avoid mistakes

A proper measure is essential for a perfect fit. As all orders are custom made, any mis-measures cannot be returned or refunded. If you have any questions or concerns regarding how to measure, please feel free to contact our cusomter service.

How will the blind be fitted?
INSIDE THE WINDOW FRAME
(IN-REVEAL)

1.Make sure that your window has enough depth to accommodate the product you have chosen.

Refer to the "Installation Requirements" section for the product you have chosen. If your window does not have the required depth, choose another product, or consider installing it on the outer frame (i.e. face of window).

2. Provide the full window opening size. Take NO deductions. The factory will ensure that your product will fit snugly in the window, and will operate properly.

Please note that inside mounted roller blinds will have a vertical light gap between the shade and the window frame of approximately 10mm on either side to accommodate the operating mechanisms at the top.

Width: For Roller Blinds and Vertical Blinds, record the width at the top of the window only. For all other blinds, record top, middle and bottom measurements, using the narrowest measurement.

Height: Measure the height in 3 places; left, center and right. Use the shortest measurement for Vertical Blinds. For all other blinds (including roller blinds), use the longest measurement.

OUTSIDE THE WINDOW FRAME
(FACE FITTED)

1. Specify the exact width and height you want your product. Your product will be made to the exact size you specify.

2. You should include additional height for the mounting brackets, which are up to 6cm long.

3. Add extra width on the sides, top and bottom for more privacy and light blockage.

Usually 100mm more for blinds installed over doorways, or cinema rooms.

Its good practice to deduct 20mm from the height, if the blinds are to come near the floor. 20mm will ensure they are not made too long and avoid floor contact.

4. Be aware of obstructions like molding, doorknobs, mullions and deadbolts that might get in the way of your blind.

Some blinds are available with extension brackets to help clear these obstructions.

PLEASE NOTE: IF YOU SUPPLY INSIDE-REVEAL DIMENSIONS WE WILL TAKE RELEVANT DEDUCTIONS. IF YOU SUPPLY FACE FITTED DIMENSIONS, WE WILL MANUFACTURE TO THOSE EXACT SIZES.

  • Timber Venetian blinds are horizontal blinds made from either real wood, or from synthetic material that have the look of real wood blinds. They usually come in 50mm wide slats. Aluminum blinds however, often referred to as venetians or simply venetian blinds, are the standard horizontal blinds that are most common in windows and usually come in 25mm aluminium slats.

    • Face Fitted Instructions

    Measuring - Inside the Window Frame

    • Use a steel measuring tape.
    • Measure to the nearest millimetre - don't round your measurements.
    • On your notes, clearly indicate which measurement is the width and which is the height. It is very common to transpose measurements. Always indicate the WIDTH measurement first, then the HEIGHT last. (W x H)
    • Remember one very important thing when measuring for inside reveal - Take the ACTUAL WINDOW OPENING SIZE to give to us, our factory will take all the proper allowances for it to fit into that opening.

    Is an Inside Mount Right For Your Window?

    Before taking any measurements, step back from your window and decide if you want to install the blind inside the window recess, or outside on the wall or outer frame. We usually recommend an inside installation when possible because it provides a cleaner look. However, Face Fitted can make a window appear larger or hide an unattractive window. For an inside fit, the window opening must have enough unobstructed depth to allow for installing. When measuring for Face Fitted, be sure to allow for the height of the product's headrail in your measurements. We will custom make your blinds to the sizes you write on the order. If these sizes are incorrect it is impossible to change the blind, so take your time and double check your measurements.

    Specific Measuring Instructions Below:

    For an inside mount:

    Measure the opening width at the top, center and bottom, recording the narrowest width. Always measure to the nearest millimetre, and be sure to use a steel tape measure. See tip below.

    Measure the height left, right and center, recording the tallest height.

    When you specify inside the reveal, the factory will make your blind slightly narrower than you specified to allow for operating clearance. They will deduct between 5mm and 7mm from the width. The deductions are made so that the blind will not rub or scratch your window frame. Do not take the deductions yourself; Provide the exact blind width!

    For a flush in-reveal fit (the blind completely recessed so that the top of the blind does not project out of the opening) check that you have enough depth in the window frame.

    Tip: When measuring, don't be surprised if your windows aren't square - many aren't. If they're a little out of square, it probably won't be noticeable. If your window is significantly of square, you might want to consider an Outside Mount to hide the window.

    Measuring - Face Fitted (on the outside of the window)

    • Use a steel measuring tape.
    • Measure to the nearest millimetre - don't round your measurements.
    • On your notes, clearly indicate which measurement is the width and which is the height. It is very common to transpose measurements. Always indicate the WIDTH measurement first, then the HEIGHT last. (W x H)
    • Remember one very important thing when measuring for an outside mount - Add at least 100mm to each side of the window opening for minimum light gap coverage and maximum privacy. That means 200mm longer than the actual window frame, and the blind track go beyond the frame.

    Is an Outside Mount Right For Your Window?

    Before taking any measurements, step back from your window and decide if you want to mount the window treatment inside the window recess, or outside on the wall or molding. We usually recommend an inside mount when possible because it provides a cleaner look. However, an outside mount can make a window appear larger or hide an unattractive window. For an inside mount, the window opening must have enough unobstructed depth to allow mounting. When measuring for an outside mount, be sure to allow for the height of the product's headrail in your measurements.

    We will custom make your blinds to the sizes you write on the order. If these sizes are incorrect it is impossible to change the blind, so take your time and double check your measurements.

    Specific Measuring Instructions Below:

    For Face Fitted (on the outside):

    Measure the opening width. If there is room, add at least 100mm to each side of the window opening for minimum light gap coverage and maximum privacy.
    Measure the opening height. Add a minimum of 60mm in height to allow space for mounting brackets above the opening plus enough overlap for the bottom. After determining the measurements that you want the blind to be, hold the tape measure up to your window and visualize what the overall size will look like on that window before proceeding.

    French doors

    The wider and taller you specify your product, the better your privacy, insulation, and light control. You also need room for the mounting brackets at the top (between 50 and 70mm), and the optional hold-down brackets (about 50mm) at the bottom. Consider mounting the window treatment a bit higher than you’d think so when the blind is raised it blocks less of your view. Add at least 70mm at the top.

    For the width, add at least 25mm to 50mm clearance on both sides of the glass. Usually the deadbolt latch however, will constrain the width you’d prefer. The product will usually fall just inside the deadbolt. In the case of a lever handle, certain products will slip between the handle and the door.

    All products will work on either a wood or metal door. For metal doors, you’ll probably need "metal screws" designed for attaching to metal doors, which are normally hollow.

    Measuring for a Window with Trim or Molding

    If you are using an outside mount and your window has trim, you should measure from the far left side of the trim to the far right side of the trim (so as to cover all trim from the start of one side to the end of the other). Give that measurement as your width. If you would like for your window trim to show, then give us the measurement of the window opening. If you want some trim covered but not all, add that amount to the width and be sure to add for both sides (exmaple - you want to cover 50mm of trim, so you would take the window opening width, and add 100mm (50mm of trim to cover x 2 sides). For the height, measure from the top of the trim to the bottom of the trim or sill. If you wish to mount above the trim, measure starting 50mm above the molding to the bottom of the trim or sill, and that will be your height.

    Tile and wood obstructions

    Sometimes tile or trim wrap around into the window, usually a few cm's from the bottom. This is common near kitchen sinks (back-splashes) and bathtubs. Most products can be cut by the manufacturers on the products’ sides to accommodate this. There is a slight surcharge depending on the product and whether the cutout is on one or both sides.

    Measure so that your product hangs in front of the crank. Consider adding around 25mm so to mitigate the slight bulge the product will make as it hangs in front of the crank. Also, the crank can usually be removed or re-positioned to point upwards, which minimizes its projection and obstruction. You may also be able to find a crank replacement device that looks like a wing-nut, and has a tiny projection.

    Sliding Doors

    Verticals can be installed either within the door frame or over it on the wall. We recommend installing on the outside frame of the door way. When determining this however, consider whether the handle is an obstruction, and the amount of depth available. There is sometimes a trim near the baseboard which may have to be removed, or at least taken into consideration when determining width. For an outside mount it is normally sufficient to measure about 100mm wider on both sides. The wider you specify, the better your privacy, insulation, and light control. For the height, specify about 150mm above the top of the frame. A typical height for a vertical is 2130mm; however, whatever you prefer is fine.

    Corner windows

    When twoVerticals meet in a corner, there can be a privacy problem. That's due to a gap where the products "meet". In order to minimize the problem, consider making one product bypass the other, then specify the other product to butt into the first. (See illustration below.)

    Bay Windows

    First determine the depth of the product you are installing. Most verticals, rollers, and venetians will fit nicely into most window depths. The middle window B will always be wand controlled, as there is no alternative to affix the operating chain.

    The wider and taller you specify your product, the better your privacy, insulation, and light control.
