Interior Doors - Measuring and Swing

Speed and Cost Tip - Use standard door sizes when ordering for doors.  While you can get custom door sizes, they cost a bundle and take forever.  Your fastest and cheapest option is to secure pre-cased and pre-hung stock sized door slabs.  These slabs usually come in 2" increments and are measured by the foot.  i.e. a 24" door slab becomes a 2'0" slab.


Start by talking to local Building Supply locations and see who offers a line of doors.  If you can find the door supplier who supplies the local Track Builders, then you are at the right spot.  They are often the preferred Flip supplier as they have good pricing and fast availability.


Cost Reference - Casing these doors on site is both time and money.  Also if the door was not installed properly, then the casing can look really poor, or take time as the door is uninstalled and re-installed.  The cost for having these doors pre-cased in the factory cuts the time down signifigantly and the costs are about 1/2 of what they would be if we had to buy casing, have it delivered, and pay the Carpenter to case each door opening on both sides.


Door Opening Size - Ensure the Framers make the door opening 2" larger than the desired door slab size.  This accommodates for the jamb and leveling of the door. 


When measuring existing openings, subtract 2" and round down to the next available size.


Note: If you are unsure what sizes are available, provide the Rough Opening (RO) Size to the Door Supplier and they will be able to help you.


Pro Tip #1 - Mark the door openings on the Hinge side with the following - Door Number, Swing, Rough Opening.  This will make installation a breeze as the labels on the openings will lead the Installer to the right door.


Pro Tip #2 - Make sure to think about key equipment that has to go into places after completion.  I have seen a number of houses require the removal of the door assembly entirely to get the Washer and Dryer into the laundry room due to poor planning.


Pro Tip #3 - Plan Ahead.  I have seen numerous problems after door installation where the door will hit the toilet, vanity, or tub.


Pro Tip #4 - Casing Thickness.  Another Plan Ahead situation i have run into a few times is where the vanity is tucked right next to the door.  Make sure you have enough depth for the vanity and it doesn't interfere with the cabinet countertop.  If you keep a 4" thickness away from the door for both countertops and light switches, you will be in good shape.  6" away for window casing.


Door Swing - For interior doors it becomes easy, put your back against where the hinges will go and pretend your arm is the door.  If you are using your right hand, the door is Right Hand Swing.  If using your Left, then it is a Left Hand Swing.


Throat Size - On most new construction homes the walls consist of a 2x4 on it's side (3.5") and 2 sheets of 1/2" drywall, or an overall thickness of 4.5".  This is the standard "throat" size of most pre-hung and pre-cased doors these days.  However, if you are working in an older home where the 2x4's are nominal 2" by 4", and/or you have plaster on the walls that is thicker than the dryall, then you need to take into account a thicker wall measurement and use a slip-jamb for your doors.  Discuss this with your door supplier and see what are the fastest and easiest options.


Hinge Type and Color - For most it is just a decion on color as door hinges are not typically a "feature item".  However, you will need to select the color of hinge or if not, you will receive the standard which is is typical brushed stainless look. 


Door Casing - Discuss this with the Door Supplier at the time of order, but for the most part most suppliers have standard door casings they pre-install.
