How far apart to space wall studs?

A few words about stud spacing

Wall studs serve as a wall’s backbone, giving it rigidity and allowing it to carry vertical structural loads. While wall studs are typically spaced 16 -24 inches apart,  (or 400mm – 600mm apart) it depends on each house design and load-bearing/ lining requirements.

There are a lot of factors that determine what appropriate stud spacing can be. Additional studs affect the spacing and are also required to hold windows, doors, exterior cladding, interior finishes, insulation, and other utilities. Brace yourself, because it’s time to go on a trip to learn about proper stud spacing.

Why is it important to have the proper spacing of wall studs?

Knowing how far apart are wall studs is crucial to structuring a home. So why do we need to know the distance between studs interior wall?

1. Required fixing for interior linings

Fixing interior linings such as drywall and plywood requires well-positioned wall studs [1] at the end of each sheet. Interior lining panels are quite heavy on their own.

Having proper stud spacing not only allows for better support with lesser material but also makes panel installation easier and faster. This is because proper spacing closely follows the dimensions of panels to minimize material wastage.

2. To meet bracing fixing requirements

Wall bracing runs diagonally and is fixed at the corners between studs and at the top or bottom plate.

Because of this, stud spacing determines a bracing’s overall length.

Having proper spacing will ensure that the bracing can handle even heavier loads throughout the wall’s entire structure.

3.Required fixing for wall claddings

Wall cladding is an external finish that functions as a structure’s ‘skin’. It serves as the primary layer of protection for building interiors and is, at the same time, an external decorative or aesthetic.

Proper stud spacing makes it easier to determine the orientation and how your chosen cladding can be or should be installed to reach buildings bracing requirements for its wind zone or earthquake risk. 

Considerations when spacing studs

Load bearing and bracing requirements

Load bearing and wall bracing are both important structural requirements as they help provide needed stability and security to a building’s structure and integrity.

Stud spacing is mostly standardized to suit wall linings and also so you can better fit house items made to the same dimensions. 

But stud spacings also better support the weight of floors and roof structures above. Bigger, heavier homes require studs that are properly aligned with joists and rafters above so that the entire structure stays solid, and weight is transferred effectively.

Stud spacing will dictate the amount of wall lining fixings that can be used for bracing, which helps protect from structural failure in sideways movement from … earthquakes or strong wind. 

Spacings for interior and exterior linings to fix on centers

Depending on the standard distance between wall studs, you can have access to more design options which, in turn, dictates what options you’ll have for interior and exterior lining. Standard 16-inch framing already supports a variety of cladding options, from normal 4.5-pound, 4 x 8” brick cladding to contemporary 2400 x 16mm MDF, plywood, or drywall panels.

Since lining or cladding is meant to also provide an additional layer of protection, the appropriate inside-wall distance between studs helps provide an anchor as well as helps gauge your wall’s insulation and thermal affinity. 

A closer stud spacing at 16 inches (400mm) will still take standard linings as there is now fixing on every third stud instead of every second at 47 inches (Or 1200mm).

So how far apart are wall studs for different stud sizes?

When it comes to studs, dimensions matter. Larger and more numerous studs can handle more load and provide stronger support. Refer to this chart as a guide when laying out your framing plan as a international standard, also make sure to adhere to your local building code. 

How to locate existing wall stud distance behind linings?

Here are the ways on how to find the typical distance between wall studs:

Tap the walls

1. Read up on standard home structural framing, but can be dependent on where you live. (Usually 16-inch centers for American homes). 
2. Select a starting point. Electrical outlets should have a stud right next to them.
3. Moderately knock on the wall and listen for changes in the sound. A stud will make a solid thud, otherwise, it’ll be a hollow sound.
4. Mark areas that made solid thuds, be sure to do so linearly to remain accurate. 

Use a stud finder

Here’s how you can find studs with a stud finder.

1. Choose what kind of stud finder to use (magnetic, electronic, or radar).
2. Place the stud finder against the wall and move it around until the indicators either light up, make a sound, or display (LED display) the location of a stud. 

Tools needed to cut and build timber wall

To build a timber wall or timber frame, you’ll need to cut and process material first from timber stocks. Easier said than done, but the entire process is made easier thanks to the help of several tools. Some essentials would be: 

• Power saw (Preferable a miter saw and a circular saw).
• Electric planer (To remove humps).
• Slotting & mortise machines for joinery.
• Power or a cordless drill (To drill holes for hold-down bolts).
• Chisels (For checking-out grooves for straps so they don’t protrude).
• Air or gas nail gun.
• An Adze or your modern titanium hammer.

How to measure and mark wall stud centers?

A 16-inch center means that the center of each 2×4 stud is exactly 16 inches apart. The same concept applies to 24-inch centers. Depending on what the framing of your house is, in general, you’ll want to: 

1. Find out what is the distance between studs in a wall by tapping or using a stud finder, identify the end stud or the closest one to it. Mark.
2. Decide on if you are going to mark centers or the side of each stud.
3. Measure correctly either to the center-right or left of that stud. And continue using a single running measurement to avoid errors by manually adding on the next spacing mathematically.
4. Make sure to do running measurements and check consistency by using a framing square along with a measuring tape.

How to install wall studs?

If the distance between your floor and ceiling is even all throughout the length of your wall, simply cut your studs to fit the same size. If your floor-to-ceiling measurements vary, then you will have to cut each stud manually as you go. 

1. Mark stud positions on both the top and bottom plates while observing proper spacing.
2. Insert your studs between the plates starting from both ends, working your way towards one end of the wall.
3. Fix each one to both plates using 3 ½-inch flat head nails. Or with a nail gun
4. Affix doorway and corner studs last as these would require jack studs which are shorter than the regular. These will also require straightening and spacing to allow the door to swing open.

Why should you pre-cut nogs/dwangs?

Nogs should always be pre-cut in uniform sizes for speed and to help in stud spacing. Not doing so can lead to irregularities in the spacing and can even cause bowing or warping if the length of the nogs varies within a single vertical group. 

Pre-cutting all your standard nogs at once will save time from individual measurements and walking back and forth.

How to install nogs and straighten corners?

1. Keep in mind the framing spacing you’re using. This will determine the length of your nogs.
2. Determine the number of nogs needed between studs to be able to space them evenly.
3. Mark the positions of the nogs on both end-studs, starting from the bottom plate. Transfer these marks to all studs using a chalk line.
4. Use a miter saw to simultaneously cut all nogs to the same length.
5. Nail the pre-cut nogs to both end-studs.
6. Leave nogs in external corners or by doors out last to be able to do custom-cuts to make the corners straight and Plumb by using a  straight edge or a laser level when measuring their length.

Knowledge about stud spacing is important!

When determining how far apart should wall studs be follow the standard as wall studs centers serve an essential purpose in construction. With the introduction of modern building codes, the wall stud spacing layout is standardized in order to meet the right load-bearing requirements.

This knowledge along with reliable tools, such as stud finders and power saws, will definitely help you in cutting, fabricating, and building sturdy walls and structures.
