Introduction to How to Trim an Interior Door Width

Trimming an interior door width may seem intimidating at first, but it doesn’t have to be. With the right tools and techniques, you can successfully trim an interior door without damaging it or your home’s interior. When done properly, trimming an interior door width is a straightforward task that can help you customize your space.

To correct a doorway that is too big for standard interior doors, you will need to measure and cut the excess wood. This process involves making precise measurements of the wall opening while accounting for the doors casings and jamb material as well as any additional clearance needed. Once all measurements are taken, a circular saw and other woodworking tools are employed to reduce the door’s width size until it fits correctly within the frame. You should also consider reinforcing any cuts made with wooden strips or shims in order to ensure strength and stability when reinstalling the trimmed door back into its frame.

Interior doors must be made slightly wider than their openings so there isn’t a large gap during installation because of settling walls or sagging finished floorsing . In many cases, this extra width can often be cut off before installation. Though this may seem like a difficult task, with patience and concentration you can easily achieve high precision accuracy—the key factor when dealing with intricate carpentry work such as trimming delicate raised paneled doors or matching newly installed hardwood floor thresholds with old existing ones that have been partially covered by jambs sitting over subfloors with built up heights.

In summary, trimming an interior door can be done successfully if done methodically; first accessing what parts of the opening will need to adjusted or removed along with finding out how much wood needs removed down each side in order create a uniform smooth cut to match existing floor thresholds levels (or subfloors if necessary). Following this guide should help ensure steady progress while still allowing creative expression in dealing with tricky situations such as curved contours at either end of casing corners extending along upright studs applied where decorative elements meet entryways comfortably throughout low traffic living spaces ideally designed for personal style preference satisfaction!

Tools and Supplies Needed for Reducing the Width of an Interior Door

Reducing the width of an interior door is a DIY task that requires some knowledge to do correctly. Before you begin, it’s important to be well-informed and have the appropriate tools and supplies in hand. After all, cutting the door too narrow or unevenly could mean starting from scratch. So, whether you’re hanging a French door or replacing a pocket or bi-fold model, here’s what you need for this project:


● Circular saw – Make sure your saw has a carbide blade with 24 teeth per inch and check that your blades meet ANSI standards before beginning. A plastic guard must also be installed at all times while working to prevent accidental contact with the cutting area.

● Measuring tape – The measuring tape should be at least 16 feet long; longer if necessary to measure your entire opening properly. Have several smaller ones handy for more precise measurements as well.

● Pencil – Pencils will help you mark exact placement of cuts while keeping surfaces free from permanent markings such as sharpie inkdots.

● Chalk line – Measure across the top of the door and draw two lines on each side using chalk line so you know exactly where to cut without making unnecessary adjustments later on down the road. Also helping prevent off center cuts which can hinder installation success immensely.


● Sandpaper – Use light grit sandpaper or fine steel wool to sand down any rough edges that are left over after sawing so they don’t snag on clothing and skin when handled post installation & paint application. Course paper may further mess up finished results so stick with finer one instead just in case based on advice from Carpentry professionals everywhere!

● Masonite Joint Compound – This material should always be used when cutting through masonite hollow-core surfaces since it prevents dust particles from entering crevices after removal as well leaving behind smooth, professional results every time! Talk about maximum savings! Plus no high priced contractor required.. Yay!!

● Adhesive- Some thicker types such as construction epoxy work best & offer extra security between mating frames when framing too small pieces together experimentally- ensuring tight joint closures behind completed renovations guaranteed 100%. Plus grab whichever adhesives promise quicker drying capabilities but still maintain rock solid, never budge unions all day long 😉

By following this list closely and studying tips & tricks regarding efficient usage before starting out, there’s no doubt reducing an interior door’s width accurately is way easier than expected upon closer examination 😉

Step-By-Step Guide To Trimming An Interior Door

Trimming an interior door, or any door for that matter, is not something to undertake without planning and attention to detail. It can be a complex job, but when done correctly, it will give you a professionally finished look which enhances the appearance of any room. To help make this tricky job as straightforward as possible, here is our step-by-step guide to trimming an interior door:

1) Before starting the job check there are no obstructions in the doorway e.g. furniture -you’ll need free access right around the frame and door to be able to hammer nails through into the wall and floor securely.

2) Measure precisely how much needs trimming from the bottom of your internal door; typically you’ll want to trim between 6mm and 12mm (1/4″ and 1/2″) from each end of your interior doorway as standard practice gives you a 2mm gap all round when closed.

3) Close off the base of any radiators or other heaters at either side of your doorway using appropriate products so you do not damage them when cutting away excess wood from your internal doors frame. As we’ll be sawing close by these appliances its best to ensure they’re unplugged too!

4) Hammer a scrap piece of 2 by 4 into place over both gaps in the threshold (the area where you plan on trimming down your indoor doorway). This provides extra cushioning in case there’s any deflection whilst clawing out excess softwood with a handsaw or chisel later on!

5) Set up two sawhorses along either side of your internal doorway; they should sit within 150mm range apart so you have plenty room lower in edging tools within reach. Make sure they’re stable before continuing work!

6) Cut away at surplus vertical sides with a skill saw (or circular saw in review cases), ensuring there is always equal width left when released up against both walls of the masonry frameset its filling into position with plastic spacers before fastening off …

7) Clear all chips away using an old paintbrush – if these clogs become ingress for moisture then it could result in mould build up over time!. As well as vacuuming out dust particles remaining below horizontal threshold components afterwards make sure none remain inside slots either -these can both result in disruptive rattling too if left untouched!

8 ) Check again that all measurements taken are exactly what is required before drilling holes into walls & framesides; use specialist fixing points suitable for material being used (e.g brickwork etc). Hammer nails into position through aperture spaces created once more one after another until secure enough fixings found onto mortar surface behind rim pressed flushly against masonry frameset’s thickness… (Be gentle though remember even small amounts pressure applied possibly dent materials if too forcibly pounded!)

9 ) Carefully “unclip” plastic spacers placed beneath thresholds prior touching alignment adjustment screws hole drilled oneside . Once unlocked tapped small pin next looped large ‘knocker head’ plate fixed securely through hole giving tightening movement knob visible outside both edges securing itself?

10 ) Finally test opening & closing operation several times once perfect fit achieved preventing further edging down cutting back additional amount anything felt unnecessary anymore , carefully seal gaps sides omitting draft noise pollution noises unwelcome visitors may attempt sneaking through space allows!!

Troubleshooting Common Issues When Trimming an Interior Door

Trimming an interior door isn’t always a straightforward process, and you can end up with a wonky fit or an uneven trim. However, if you troubleshoot these common issues, you can get the job done without any trouble.

First of all, it’s best to measure twice and cut once when cutting the door down for the trim. If there’s even a small miscalculation, it could affect how the trim looks afterward. Measurements should be accurate to the nearest millimeter to get high-quality results. If possible, use a jigsaw with a saw blade specifically designed for working with wood in order to get a precise cut that follows the shape of your template perfectly. For extra accuracy, use masking tape along your mark lines as this will help keep them distinct while cutting.

Sometimes, when nailing together door frames or baseboards, nails may go awry and cause gaps between pieces that create an uneven look after painting. To fix this issue, fill any screw holes or nail gaps before priming by using wood filler which hardens quickly and paints over nicely once dry.

Also take note of joint spacing; when attaching joints such as corner posts they shouldn’t be too close or too far apart otherwise you could be left with unsightly gaps in between them when painting over them. It helps to install pieces first before attaching trim so you can make sure everything is snug but not overly tight against each other which might buckle paint later on down the line.

Lastly, when fitting your door casing always make certain that everything is secured tightly against surfaces without any major buckling happening; if necessary pre-drill holes where needed for anchoring screws securely into wall studs so it’ll stay affixed in place securely afterwards during primer coat drying stages but don’t hammer them all in just yet! This way too much pressure isn’t exerted upon doors leading plastic-ware components inside (door handle assembly hardware must also correspondingly fit as such at this time); finally – thoroughly dust off area before starting painting/primer tasks on wooden materials per manufacturer guidelines since previous sawing dust particles could visibly remain behind spoiling finish quality levelmanship standards of Product achieved here (which will thereafter directly reflect on overall point rating review sheet ratings herein prior).

Top Five Facts about Trimming An Interior Door

Interior door trim is a common consideration when renovating a home. It can make a huge impact on the overall aesthetics of your interior spaces. There are many things to consider when choosing the right trim for interior doors, from design and materials to installation techniques. To help you get started, here are five important facts about trimming an interior door:

1) Pre-Trimming Measurement: Knowing the accurate measurements of your interior door can help you decide which type and size of trim will work best with its dimensions before you purchase anything. Door manufacturers supply jamb widths with pre-trimmed measurement information included in their specifications, so make sure to take this into account before making any decisions so that your selected trim fits snugly against the jamb’s edges without overlapping or leaving gaps when installed.

2) Optimal Adhesion: Nails and adhesives both have their uses in door trim installation, but only one should be used at each joint since these two fastening methods often compete for dominance once applied simultaneously. For optimal adhesion and stability results, it’s recommended that nails be used along joints that don’t require much movement during use (such as corners), and good quality sealants or glues can be used for larger pieces and those joints that may experience more wear due to frequent movement over time (e.g., hinges).

3) Finishing Techniques: Many different types of finishes can be applied to an interior door after it has been trimmed such as paint or stain to compliment the look of other elements within the space like molding, cabinetry, flooring, etc. Finishes protect wood from being damaged while also enhancing its appearance over time. As such, it’s important to go with high-quality products specifically designed for interior doors so as not compromise its structural integrity in any way throughout usage over long periods of time.

4) Suitable Joint Accessories : A variety of suitable joint accessories should be considered when installing an internal door trim such as screws/bolts, mitered joints in which adjoining trims fit tightly together at an angle/corner ring shank nails which provide greater resistance against shear forces than standard flathead nails do, etc. Additionally choosing decorative coverings like brass finish plates or wood strips around certain screw heads adds a sophisticated touch while providing further durability and increased security features depending on what type is chosen (e-stoppers are great options here).

5) Taking Account Of Clearance Space : When selecting trims for interior doors, accurately measuring out clearance space so there’s ample room around all edges of the frame is essential as this ensures smooth operation whenever opening/closing happens without causing unwanted friction damages due to inadequate spacing constrictions being present between wood components if they were too close together initially – eave 1/8 inch gap allowance between opposing sides occasionally where possible just incase!
