Plantation shutters have a way of making any room feel timeless, fresh, and stylish. Here at Modern Group, we often get asked about the difference between inside and outside mounts, how to measure them properly, and the best way to install them.
Choosing the right mount, and getting the measurements spot-on, can be confusing. This guide will walk you through everything you need to know about inside plantation shutters, from measuring and installing to deciding between inside or outside mount plantation shutters.
Inside plantation shutters are designed to fit neatly within the window recess rather than being mounted outside on the architrave or wall.
This style is popular because it creates a seamless, custom-built look that blends perfectly with your windows. Unlike curtains or external mounts, inside mount plantation shutters feel integrated into your home’s architecture.
If your windows have enough depth, inside plantation shutters are best and often the most stylish and functional option.
One of the first decisions you’ll make is inside vs outside mount. Each has its advantages, and the right choice depends on your windows and your design goals.
| Feature | Inside Mount Plantation Shutters | Outside Mount Plantation Shutters |
| Location | Installed within the window frame | Installed on the wall or architrave |
| Look | Clean, minimalist, built-in | Bold, makes windows appear larger |
| Window Depth Needed | At least 60–70mm | Minimal depth required |
| Best For | Modern, neat finish | Hiding frame imperfections, tricky windows |
| Downsides | Won’t work with shallow recesses | Less “seamless” look |
Modern Group Tip: If your frames are deep enough, inside mounts give the sleekest, most custom result. But if your recess is shallow or uneven, outside mounts might be the smarter choice.
Measuring correctly is the single most important step in ordering shutters. Even being out by a few millimetres can cause problems with fit or function.
Always double-check your numbers. A 1–2mm error can throw off the entire installation.
If you’re handy, you may want to install your plantation shutters yourself. Here’s a step-by-step process:
Lay out your panels, frames, screws, and hinges. Check you’ve got everything.
On the floor, connect the frame pieces together. Ensure corners are square.
Lift the frame into the window recess. Use a spirit level to check it’s straight.
Drill pilot holes, then screw the frame into place. Start with the top, then sides, then bottom.
Hang the shutter panels on the hinges. Open and close them to test alignment.
Make small adjustments to ensure everything swings evenly. Tighten all screws.
And that’s it, your inside mount plantation shutters are ready to enjoy.

Measure your window, assemble the frame, secure it within the recess, then attach the panels. Always use a level for accuracy.
They can do both. Inside mounts sit neatly inside the recess, while outside mounts attach around the frame.
The process is the same as inside mounts: measure, assemble, level, secure, and attach.
Take three width and height measurements, always using the smallest figure. Don’t forget to check the depth.
