In What Direction Do I Lay My Hardwood Floor?


Last Updated: 7/27/2021


The most common way to lay/install hardwood or bamboo flooring is by aligning the planks parallel to the longest wall or run in the installation. Apart from a few exceptions like sagging joists, this is the preferred direction to lay wood floors because it provides the best result aesthetically. This means running the planks lengthwise straight away from your front door to the back in most homes.

The one exception is if your sub-floor is sagging between the joists – in which case you’ll want to run the planks across the flooring joists to avoid any problems. Try to avoid changing directions on your floor in different rooms, and do your best to plan the exact layout before beginning your installation.

How To Lay Hardwood Floor

If this is the first time you’ve laid a hardwood or bamboo floor, it’s natural to wonder in what direction the floorboards should run. Although it may not seem obvious, laying your floorboards in the right direction adds a lot to the finished floor’s overall look. Here are a few things to keep in mind when preparing to lay your new floor, so the finished product looks like a pro did it…

Check Out Your Joists and Existing Sub-floor

 

Modern Style HomeNewer Homes (built post-1990’s)

Due to stricter building codes, newer homes have more level sub-floors required by code to meet minimum deflection ratings. Therefore, the direction you lay hardwood floors in a new home is based more on aesthetic and design factors than the direction of the joists. In these instances, the hardwood floor planks are usually laid parallel to the longest run or wall in the installation.

If you’re laying your new floor in an older home with a plywood sub-floor, the first thing to consider is the direction of the floor joists that support it. In these cases, the conservative choice is to go perpendicular across the floor joists and allow them to support the new floor and the sub-floor. If you go parallel to the joists, you may end up with flooring areas that aren’t fully supported. Over time, this can lead to the sub-floor sagging in between the joists, and if the sub-floor sags, it could potentially cause your hardwood floor to buckle, leading to the joints breaking. That’s not the outcome you’re after! That leads to the need to replace floorboards, and a new finish for the entire floor would be necessary so that everything matches (See how to refinish bamboo flooring).

 

How to Analyze Your Subfloor

Whether the home is old or not, always inspect the subfloor first to determine how flat it is. Is there obvious sub-floor sagging between the joints visible to the naked eye? Does the sub-floor bounce considerably when walked on? If the answer to either of these questions is yes, you will want to lay the hardwood planks across the floor joists in a perpendicular fashion. Still in doubt? You can also use tools to measure the deflection or flatness of the floor, and of course, you can also hire an engineer to inspect the floor joists and sub-floor to calculate deflection and grading.


tip-for-DIY-flooring-installTIP: Once you’ve determined the floor joists’ direction and position, mark them on the wall where the base molding will hide them when you install it. This will allow you to measure 4′ in from each end of the long wall, mark your measurements, and then snap a chalk line between the two marks on the underlayment to serve as a guideline when you’re laying your first rows of boards, keeping them straight and parallel to the wall. (Note: It’s a good idea to measure from your marks to the opposite wall, too. If the measurement is the same, the walls are parallel. If it’s not, you’ll need to adjust your guidelines to account for the difference.)


Your New Floor and Your Front Door

If you’re laying a hardwood floor near your front door, you may want to consider laying it so the boards run perpendicular to the entrance, if you can. Why? Laying the boards in this way allows them to flow naturally with traffic and looks better.

Consider the Dimensions of the Room

If you’re laying your new floor in one particular room, like a bedroom, for instance, it’s wisest to lay the floorboards parallel to the longest wall in the room. If you lay them perpendicular instead, and the room is somewhat long and narrow, your floor will end up resembling a ladder!

Getting Fancy

You can always opt to lay your floor on the diagonal or choose an interesting pattern like a herringbone. Patterns can add depth and dimension to a room and are unquestionably beautiful when done correctly. If you choose this option, though, you’ll need to consider a couple of important factors:

  • It’ll cost you more since you’ll need to add 15% (as opposed to the usual 10%) extra material to account for cutting and waste.
  • Patterns, especially complicated ones like herringbone, really require a seasoned hand to lay, so it’s probably not a wise choice if this is your first go-round at laying a hardwood floor.

Think About the Light Source

If you’re installing your new hardwood flooring in a room with lots of natural light, you may want to consider running the boards in the direction of the light. That’s because if you run them perpendicular to the light source, the light will run across each joint, and any slight variation in the height of the boards will show up and cast a small shadow. Running your floor in the same direction as the light source eliminates this problem and results in a better-looking floor.

Some Handy Tips for DIYers

  • At floor heating registers, make sure to cut your boards to fit the opening before installing them.
  • Suppose you’re abutting a fireplace hearth, miter the boards to create a neat border that will frame it. Glue the boards in place and then face nail* them. You might also think about gluing the ends of any boards that fit snugly against the hearth.

*If you are nailing by hand, be sure to drill a small pilot hole in the surface of the floorboard, then drive a finishing nail in until its head almost reaches floor level. Finish driving the nail using a hammer and a nail set. Afterward, fill the hole with wood putty and wipe away any excess.

Consider a Bamboo Floor

If you haven’t yet purchased your flooring, consider the advantages that strand woven bamboo flooring offers. Besides the fact that it’s as attractive as any hardwood flooring, it’s also way harder than almost any hardwood you can think of. It’s also a greener alternative since bamboo is a grass that grows immeasurably faster than a replanted hardwood tree. (We’re talking about 4 years vs. decades!)
