Beautiful space! I think the rug size depends on where the end of the rug lands in relation to the hallway. Probably the 9 x 12 option but I'd make sure when you walk out of the hallway, you walk both feet onto the rug, not one foot on hardwood and one foot on carpet.

Colour ... looks like you're going with neutrals and you can't go wrong really. Could get a rug in neutrals and soft colours if that's what you want too - any muted colour you like ... grey blue, aqua, clay, sage, ochre ... then repeat in the pillows and art. Please post when you're done!

Thank you so much for your input! It helps me a lot🙏🏻☺️ I wanted to upload the hallway picture to give you guys an idea of the space I have to work with. Thank you again for taking your time answering 🙏🏻

How about a gold rug to bring out your beautiful lamps. Love your space.

Ohhhh never thought of that color option 🤔😍 thank you for sharing your idea!

Tmac mentioned traffic pattern at the foot of the bed so 6x9 or 9x12. The size depends on the size or the room and/or the bed area.

I agree neutrat for this room or with hints of soft color. You can't go wrong with an undyed hand woven wool rug.

Finding the right color will be tricky but I think there are blush rugs out there since it's the current trend. Order a small rug to check color first so you're not hauling huge rugs back and forth to the UPS or rug stores.

I found these on Rugs-Direct.com You can try them out in your photo.

Lovely bedroom!

I’d go a bit dramatic, and bring in some warmth for a luxe feel. Something with charcoal and/or black in it. I love mixing a traditional rug with glam and sleek. It’s a more timeless look.

These all have a hint of gold to tie in with your lamps.

Bigger, but the mock-up skewed the pattern:

This one is a bit edgier:

This is a striking rug, you’d just need to make sure it wouldn’t clash with your bed color:

Going pricier, but there are some gorgeous rugs here, more heirloom category. Example:

This Karastan is ekegant and gorgeous. I had to mock it up small, due to the pattern, you could go bigger:

Anyway, unless you want a monochromatic look, you don’t have to stick with all gray rugs. I look at rugs as art on the floor. :)

If you do decide to go with a more monochromatic look, some lovely examples here:

Tape it out. You also have an angled fireplace that might restrict the size of your rug in the room.

@ptreckel is right. Painter’s tape saves you a lot of time and money ordering the wrong size.
