Adjusting Ready Made Venetian Blinds

Many people shopping for venetian blinds will probably be considering purchasing one of the ready-made venetian blinds that most people have seen stacked up on racks in diy and interior furnishing stores. As there are now such a wide range of styles and sizes of these types of venetian blinds available, many customers considering a venetian blind for their home may think that buying a ready-made venetian blind must be the most convenient way to purchase and may not even consider exploring whether made to measure venetian blinds would be more suitable for them. However if you buy a ready-made venetian blind then unless you are very lucky, and find one in the exact size you need for your window, it is likely that you will have to adjust your venetian blind to fit your window, and this can be tricky and time consuming. Therefore if you are considering buying a ready-made venetian blind then please read on, this short guide should help you decide whether buying and adjusting a ready-made venetian blind is the best option for you.

In order to maintain a symmetrical appearance adjusting a ready-made venetian blind will mean cutting the blind at both ends. If you are buying a ready-made venetian blind then you would normally choose the next size up from your window width and drop and shorten the blind to make it smaller to suit your window. However be careful not to buy a blind in a size much larger than the window you intend to use it on as there will be a limit to how much you can cut the blind down. Depending on the type of blind this limit is usually determined by the position of the ladder braids and lifting cords but could be due to the position of the mechanism in the headrail.

Once you have got a blind of suitable size, you can plan the job of cutting it down. Cutting the blind down can be a very tricky task so nowadays lots of the diy and interior furnishing stores that sell ready-made venetian blinds offer a cut down service. There they usually use powered saws or guillotines to cut the slats, head rail and bottom bars to the customers required size. However if your store does not offer this service then you will have to do it yourself at home. Even if the store will cut the blind down, if you want to maintain the rounded or splayed corners that are often on the slats of pvc and aluminium blinds then you may still have to trim the edges of each slat yourself by hand at home in any case. For most people cutting the head rail and bottom bar at home will normally involve cutting with a hacksaw. You should be able to cut aluminium and pvc slats with a pair of strong and sharp scissors or maybe tin snips if you have them. The slats from wood venetian blinds can be cut individually with a hand panel or jigsaw but for the best results all the slats should be cut together with a powered chop saw or bench saw.

Finally if the ready-made venetian blind you have purchased has a much larger drop than is necessary for the window you want to fit it to then you will probably want to remove some of the slats to make a better fit. Removing these slats will stop the blind looking too bunched at the bottom when closed and will also mean that the ‘stack height ‘ of the slats bunched together when open will not be bigger than it needs to be. This will stop the blind blocking more of the glazed part of the window than it needs to when it is in an open position. Removing slats from a venetian blind usually involves removing the bottom bar by unfastening the ladder braids, lifting cords and tapes, then removing the required number of slats. When the slats have been removed the ladder braids, lifting cords and tapes will need to be cut to the reduced length and then re-fixed to the bottom bar.

If you don't have the time or skills to make these adjustments, you may wish to consider ordering your venetian blinds made to measure. This option may seem more expensive however when you consider the time and effort required to fit a ready made blind, the custom made option may be cheaper after all.
