You can either measure your own kitchen or get a professional to do it. In our case, we used the later. If you are planning to measure yourself, make sure you take into account the position of your plug point, sink pipe, windows, door, kitchen's light position, height from floor to ceiling or floor to window. Basically, everything that your eyes can see, measure it. And be extremely precise. Or go to Ikea at the customer service section and ask for the person in charge of measuring the kitchen. They'll bring you to the right person. For the measuring service, depends on where you live, a certain amount of charges will be imposed. The nearer your location to Ikea the cheaper. Ours was around RM100+ but it was worth the money because their measurement is extremely precise. They'll come to your place, measure your kitchen and the measurement will be given to you on the spot. We definitely recommend you to use the professional service. You can also keep the measurement for future reference even if you don't feel like using Ikea kitchen.

Once you got your measurement, go to IKEA Home Planner, enter the measurement of your kitchen, and start planning the design of your kitchen cabinet. Don't worry about not knowing how to use the planner. Just play around with it. You'll get the hang of it pretty fast. It's very fun to see your dream kitchen coming to life. After you are done designing your dream kitchen, save it and click on the Item List / Total Price button to view exactly what the button says. From there, adjust your design to fit your budget. The materials chosen play an important role in determining the price. Choose wisely. We took the cheapest material but overall we are very pleased with everything. Read here for more details on the guarantees/warranty. The total price of the kitchen does not include the delivery price and the installation price.
