The difference between Perfect Fit blinds and standard blinds is where they are fixed. A standard blind is fitted to the wall, ceiling or inside the window recess and hangs in front of the glass. A Perfect Fit blind sits in a slim frame that clips into the beading of a uPVC window or door, so it moves with the sash when the window opens and usually needs no drilling. Which is better depends on the window, how it opens and what you want the blind to do.
How each is fitted
Standard blinds
Brackets are fixed into the recess, the wall above the window or the ceiling. The blind hangs independently of the window. This suits almost any window, including timber and aluminium frames, and gives the widest choice of blind types — roller, Roman, Venetian, vertical and more.
Perfect Fit blinds
A frame is made to the size of each individual pane and clips into the window's beading. The blind — usually pleated, Venetian or roller-style depending on the range — runs inside that frame, right up against the glass. Because each pane has its own blind, the blind opens and tilts with the window. Compatibility depends on the depth and shape of the beading, which must be checked.
The decision at a glance
| Standard | Perfect Fit | |
|---|---|---|
| Fixing | Drilled into wall, recess or ceiling | Clips into window beading; usually no drilling |
| Window types | Almost any | Compatible frames, typically uPVC |
| Opening windows | Blind stays put; may obstruct handles | Blind moves with the sash |
| Edge light | Gaps at the sides are common | Close to the glass with fewer gaps |
| Cords | Depends on the system | Typically no loose hanging cords, depending on range |
| Choice of style | Very wide | More limited |
| Look | One blind across the window | A separate blind on each pane |
When Perfect Fit is the better choice
- Tilt and turn windows and doors — the blind moves with the sash rather than getting in the way. See Tilt and Turn Windows: What to Check.
- Bifold and French doors — blinds stay neatly on each door panel without swinging. See Blinds for Bifold Doors.
- Conservatories — lots of individual panes, many of which open.
- Renters or anyone avoiding drilling — on compatible frames.
- Children's rooms — the enclosed frame avoids loose hanging cords.
- Windows opened often — you do not need to raise the blind to open the window.
When a standard blind is the better choice
- Timber or non-compatible frames — a Perfect Fit frame needs suitable beading.
- You want one blind across the whole window — a single blind gives a cleaner look than several framed ones.
- You want a soft or decorative fabric — Roman blinds, patterned rollers and many fabric ranges are only available as standard blinds.
- You want to clear the whole window of blinds — a standard blind can be raised fully above the glass; a Perfect Fit blind stays on the pane.
- You want motorisation — generally more widely available on standard blinds.
What about FITtoFRAME and other no-drill systems?
Perfect Fit is one of several frame-fitted approaches. Other systems, such as FITtoFRAME blinds, attach to the window frame in different ways and may suit frames that Perfect Fit does not. Some no-drill systems use brackets that hook over the window rather than into the beading. See no-drill blinds.
Light and darkness
Because the frame sits against the glass, a Perfect Fit blind usually leaves smaller edge gaps than a standard recess-fitted blind, which helps room darkening with a blackout fabric. It is still not a total blackout system — see Blackout Blinds Explained.
How to decide
- Check the frames. Are they uPVC with suitable beading?
- Check how the windows open. Tilt and turn, doors and frequently opened windows favour Perfect Fit.
- Decide on the look. One blind across the window, or a blind on each pane?
- Decide on the fabric. If you want something soft or patterned, a standard blind gives more choice.

Frequently asked questions
Do Perfect Fit blinds work on all uPVC windows?
Not all. The beading must be the right depth and shape. We check this before ordering.
Do Perfect Fit blinds need drilling?
Usually not — the frame clips into the beading. That is one of their main advantages.
Are Perfect Fit blinds more child-safe?
They avoid loose hanging cords, which makes them a popular choice for children's rooms.
Can I have Perfect Fit blinds on some windows and standard blinds on others?
Yes. Many homes mix the two, choosing whichever suits each window.
