When measuring your room always measure the longest point and widest point not forgetting to go into doorways or recess, the most common width of carpet is 4 metres wide and although you can have almost any length you require the width is governed by the particular carpet chosen, e.g. your room could measure 3.5 metres by 4.6 metres, you cannot times 3.5 by 4.6 to get your total metres if the width of the carpet chosen is 4metres..... You will need to times 4 metres by 4.6 metres to get the total metres you require thats the trouble with fitted carpets in able to have them fitted you need to cut them to the shape of the room so creating waste that has to be paid for.  You only need to do it for a guide for yourself so you can budget for which type and price of carpet to go for or if you want to come to our shop looking for remnants that may be suitable. In all cases we would rather measure the rooms ourselves (estimates are free) that way if the carpet does not fit its our fault not yours. Sometimes with awkward room shapes it may be best to draw a rough diagram with different sizes on it if you are coming to our shop looking for remnants or fitting it yourself that way we can sometimes suggest that a join in a recess could perhaps be a cost effective way of fitting your room without having too much waste

FITTING the carpet yourself should not be too much of a problem as long as your room is not an awkward shape or have doorways in the middle of the room. Hall stairs and Landings are another area to avoid with all those doorways. However if you are reasonably competent at DIY a sharp stanley type knife a room empty of furniture and nicknacks gives you a good start, also ask our salesmen if they think the carpet is suitable for DIY fitting , there are certain types that fray or run these types are best left to the proffesionals,
If you are fitting a carpet with a seperate underlay you may need to put gripperods around the edges of the room , the points are angled and should be facing the skirting board, leave about a quarter of an inch gap between the gripper and the skirting board (this is where the carpet will be tucked down to give a nice neat edge) at the doorways put in a doorstrip instead of gripperrod , put the doorstrip underneath the door so that it will not be seen when the door is shut.
Fit the underlay up to the gripperod laying the rubberside to the floor and the hessian or paper side up the underlay is usually laid in strips and should join quite neatly without the need for taping the joins.
It is probably easier if you take the door off its hinges before you start fitting the carpet, lay out the carpet in the room with the carpet needing to be trimmed along all of its edges (if you set a carpet off one long wall it invariably wont be straight and trying to set the carpet may lead to bubbles in the carpet) make the carpet flat without bubbles by pulling here and there only when it is completelt flat without bubbles and will cover all the room can you start cutting also check that there are no faults in the carpet it will be too late to report noticeable faults once you have cut the carpet. If everythings ok trim the carpet to within a couple of inches all the way around the room, at this point if you have bought a foam backed carpet carefully fold back half of the carpet to put the paperlay down and gently fold back the carpet on top of the paperlay (do the same with the other half of the room.
NOW on your knees with your hands push out any bubbles in the carpet untill you are quite sure it is really flat. to trim the carpet either mark it against the skirting board or cease it and cut it appoximateley 1/4 of an inch bigger all the way around the room this 1/4 of an inch will either be folded at the back of the gripper or pressed against the skirting board to give a neat edge JOB DONE
