Solid wood doors are a classic choice for home entryways. Made entirely from natural wood, these doors provide a traditional look and durability.
However, solid wood doors come in standard sizes. You may need to cut down a solid wood door to properly fit the entrance. But how much can you trim a solid wood door before causing damage?
This comprehensive guide will cover everything you need to know about cutting solid wood doors.
Benefits of Solid Wood Doors
Before we get into the specifics of cutting, let’s look at why solid wood remains a preferred choice:
- Natural material. Solid wood comes directly from trees, making it an eco-friendly option. These doors don’t contain composites or synthetic materials.
- Strength. The thick, solid wood offers exceptional durability. Solid wood doors stand up well to everyday wear and tear.
- Insulating properties. The dense wood also provides effective insulation. Solid wood doors keep interior spaces comfortable and block outside noise.
- Appearance. Wood doors can be stained or painted for a custom look. The natural grain provides an attractive texture.
- Value. Solid wood doors increase a home’s worth. They convey quality and luxury.
So, solid wood doors, in many ways, outweigh hollow or composite types. But one downside is that they come in fixed sizes. Fortunately, you can trim solid wood doors to fit your needs.
Can You Cut Down a Solid Wood Door?
Solid wood doors can be cut to size. The thick, solid construction allows doors to be trimmed within certain limits before running into issues.
You’ll want to follow guidelines on how much wood can safely be removed based on door quality. We’ll look at appropriate trim amounts in the next section.
Proper cutting tools and techniques are essential to avoid splintering or damage. We’ll outline the step-by-step process later in the guide.
While hollow and composite doors are more forgiving if you cut off too much, trimming a solid wood door is possible with care. Planning the project is key.
How Much Can You Cut Off a Solid Wood Door?
When cutting a solid wood door, there are limits to how much you can safely trim off:
- High-quality wood: 1 inch total
- Lower-quality or old wood: 1/2 inch total
The condition and quality of the actual wood impact how much you can cut from the door. Here are a few general guidelines:
- Trim no more than 1/2 inch total from the sides of the door.
- Take off no more than 1/4 inch total from the top and bottom.
- For lower-quality wood, limit total cuts to 1/2 inch overall.
Cutting more than these amounts risks splintering or exposing areas that allow drafts, moisture, and pests to enter. It also may result in an uneven or unstable door.
Always measure carefully beforehand to determine exactly how much must be removed for proper fitting. It’s better to trim conservatively than cut off too much at first.
Tips for Cutting a Solid Wood Door
Cutting a solid wood door properly involves careful prep and execution. Here are some top tips to keep in mind:
- Carefully measure the door frame and threshold where the door will hang. Determine how much clearance is needed on each side.
- Use a circular saw with a sharp blade designed for cutting wood. A worn or dull blade is more likely to splinter the wood.
- Employ a saw guide for the straightest, cleanest cut possible. A guide ensures the saw doesn’t wander while cutting.
- Work slowly and methodically when cutting. Rushing increases mistakes. Make one smooth pass over your cut line.
- Always cut with the door lying flat. Trying to trim a hanging door makes accurate cuts difficult.
- Sand down any splintered areas after cutting. Apply wood filler if needed to make repairs.
- Finish cut edges with stain or paint to match the original door colour. This hides any touch-up work.
Follow these tips, and your solid wood door will have a professional-looking cut, allowing it to fit the entrance properly. Next, we’ll review the tools you need to complete the job.

Step-by-Step Guide to Cutting a Solid Wood Door
Follow these steps for adequately cutting a solid wood door:
1. Measure the door frame.
- Use a tape measure to check the door frame opening from top to bottom and side to side.
- Deduct 1/4 to 1/2 inch from overall height and width for clearance.
- Mark how much needs to be trimmed. (Ex: 1/4 inch off top and bottom, 1/2 inch total from sides.)
2. Mark cut lines.
- Lay the door flat on a work table or sawhorse.
- Use a straightedge and pencil to mark planned cut lines.
- For accuracy, consider using a laser level to guide straight lines.
- Clamp down the door securely so it doesn’t shift during cutting.
3. Set up circular saw & guide.
- Mount a sharp wood cutting blade on the circular saw.
- Align the saw guide or straightedge along cut lines.
- Ensure the guide has strong clamps, securing it flush to the door edge.
4. Make trim cuts.
- Wear safety goggles, gloves, and a mask.
- Run saw smoothly across the door with the guide rail.
- Make multiple light passes if needed versus one deep cut.
- Trim both sides for an even appearance.
5. Sand cut edges.
- Use fine-grit sandpaper to smooth any splinters.
- Fill any gouges with wood filler; sand flat after drying.
- Touch up colour with stain, paint, or sealer for a uniform look.
6. Test door fit.
- With trimming complete, hang the door to test fit in the frame.
- If further adjustment is needed, lay the door back flat and lightly trim.
- Avoid removing more than the recommended amount.
And that’s all there is to it! Follow these six steps carefully; your solid wood door will soon fit perfectly.
How to Fix Splintering After Cutting
It’s not uncommon for some splintering to occur when cutting into natural solid wood. Luckily, these cosmetic issues are easy to remedy:
- For small splinters, gently sand the cut edge with fine 120+ grit sandpaper until smooth.
- Apply a thin layer of wood filler to fill any remaining gouges; allow to dry completely.
- Lightly sand hardened wood filler to level it flush with the wood door.
- Finish repair areas with wood stain, paint, or sealer to blend with the original door colour.
- Consider applying a thin coat of wood sealant to the entire door to prevent future splintering.
With this simple fix, your cut solid wood door will look fabulous again. The wood filler and touch-up colour disguise any repairs.
DIY vs. Hiring a Pro for Cutting Doors
Is this a DIY job, or is it best left to the professionals? Here are a few things to consider:
DIY benefits:
- Cost savings
- Convenience of working on your own time
- Satisfaction of completing home improvement yourself
Potential DIY challenges:
- Having to buy or rent tools
- Achieving clean, straight cuts
- Fixing mistakes like splintering
- Hanging the door correctly after trimming
Pro benefits:
- Perfect cuts with professional tools
- Efficient completion by experienced carpenters
- Ability to fix any post-cut issues
- Proper hanging with shims and alignments
Contractor drawbacks:
- The added cost of labour
- Waiting on contractor schedule
- Coordinating to be home for service
As you can see, there are pros and cons to both options. For many homeowners, DIY trimming will be the preferable route. But for more complex jobs, hiring a carpenter may give you peace of mind.
FAQs About Cutting Solid Wood Doors
Let’s answer some frequently asked questions about trimming solid wood doors:
Can you cut a solid wood door while it’s still hanging?
It’s not recommended. Removing the door makes accurate trimming much easier. The only exception would be sanding a minor amount from the bottom of a hanging door.
Does the type of hinge matter when cutting a solid wood door to size?
No, you can use standard hinges. Use enough (typically 3-5) to bear the door’s weight evenly.
Can you cut a solid wood door in half horizontally to make a Dutch door?
Yes. Cutting a solid wood door in half to create upper and lower halves is possible. Just follow the exact measuring and missing steps outlined earlier.
How can you tell if an interior door is solid wood vs. hollow or composite?
Solid wood doors feel very heavy and dense. Knocking on them produces a dull “thud” sound versus a more hollow echo. They also lack an outer composite frame. Checking hinge types can also help identify the material.
Should you seal the cut edges of a solid wood door after trimming it?
It’s a brilliant idea. Applying a thin coat of wood sealant helps protect cut end grain from moisture damage. This prevents future swelling or cracks.
Can I Use the Same Techniques for Cutting and Drilling Wooden Doors?
When it comes to drilling wooden doors, the technique may differ slightly from cutting, but there are some similarities. In this drilling wooden door complete guide, you’ll learn the proper tools and methods for creating clean and precise holes in wooden doors without causing damage or splintering.
Trimming Solid Wood Door
