Start at the floor
Measure between the closest obstructions, including baseboards. A wall can be wider than the usable floor space.
MAKE EVERY INCH COUNT
Will that desk fit?
Measure before you buy.
Check the fit before you buy. Plan your desk footprint, leave room for your chair, and find dimensions that work for your room.
Find my desk size ↗01 / THE FIT CHECK
What fits your space?
Measure the clear area where your desk and chair will go. Keep doors, drawers, walkways, and other furniture outside that area.
YOUR PLANNING ENVELOPE
56 × 34 in
Maximum desk width × depth for your selected gaps.
Allow for skirting boards, cables, leg clearance and assembly. A desk fitting this rectangle can still be unsuitable for your room.
CHECK A DESK YOU FOUND
Does a specific desk fit?
Enter its desktop width and depth in the same units as your room plan. This compares both measurements with your current planning envelope.
02 / MATCH THE MEASUREMENTS
Desks that fit your plan
Product recommendations are not connected yet. Use your dimensions to compare retailer specifications.
We earn commissions on qualifying purchases made through these links. Retailers handle checkout, delivery and returns. These are dimension matches, not hands-on reviews.
03 / BEFORE YOU ORDER
Measure once. Check these four things.
Pull out your chair
Sit, stand and move back as you normally would. Measure that space, then enter it as your chair allowance.
Trace the delivery route
Check the packaged dimensions against doors, stairs and turns. Check whether the desktop arrives in one piece.
Check the details
Compare the retailer's width and depth with your plan. Include monitor stands, plugs and any rear cable tray in the space you need.

Will your monitors fit?

How to measure a space for a desk
A practical measuring sequence for a rectangular desk and a real chair.
Desk width and depth: why both matter
Surface area alone cannot tell you whether a desk will fit.
How to plan space behind your desk chair
Use your own movement to choose a planning allowance.
Will the desk fit through the door?
The room footprint and the delivery route are different checks.

Desk fit calculator: common questions
How do I calculate the largest desk that fits?
Subtract twice your selected side gap from the available width. Subtract your selected chair space from the available depth. Check both remaining measurements against the desktop dimensions, then check the full frame and delivery route.
Does a smaller desk area always fit?
No. A desk can have a smaller total surface area and still be too wide or too deep. This tool compares width and depth separately.
Can I save a room plan without making an account?
Yes. Use “Copy a link to this plan” after calculating. Measurements are included in the link's fragment, which is not sent to the hosting server as part of the request. Anyone you give that link to can read the plan. No account is needed.
A simple tool. A clearer decision.
DeskSpace compares rectangular measurements. We do not test products or rank quality. Product feeds, when connected, supply dimensions and links; confirm specifications with the retailer before buying. Placement is based on fit, then desk area, rather than commission rate.
