Know Exactly What Furniture Fits Before You Buy
Drop the actual dimensions of any sofa, bed, dresser, or dining table into a scaled drawing of your room — and see in 2D and 3D whether it fits, blocks a doorway, or eats your walking path.

Who this is for: Anyone about to buy a piece of furniture they're not 100% sure about — especially big-ticket items like sofas, sectionals, beds, dining tables, or wardrobes where returns are expensive or impossible.
The Problem with Buying Furniture Blind
You measure your room with a tape, scribble the numbers, and try to imagine whether the sectional you've been eyeing will actually fit. Maybe you walk it out with masking tape on the floor. The piece arrives, and the proportions are off — it crowds the doorway, blocks the heating vent, or just feels too big.
Returning a sofa is rarely free. Many retailers charge a 15–25% restocking fee plus pickup costs, and custom pieces can't be returned at all. The cost of a wrong choice often runs into hundreds of dollars before you've even sat on it.
What you actually need is a way to check fit accurately, before you order — including walking paths, sight lines, and how the piece looks next to everything else in the room.
How Room Sketch 3D Solves This
Room Sketch 3D is a floor planner that works on web, iPhone, iPad, and Android. Here's what makes it useful for this specific scenario:
Scale-accurate room drawings
Draw your room to exact dimensions using the scale tool. Walls, doors, windows, and openings all snap to real-world measurements — no eyeballing.
Drop in real furniture sizes
Use any of the 350+ pre-measured furniture pieces, or enter the exact width × depth × height from the retailer's spec sheet. The footprint shown is what you'd actually get.
2D top-down view for clearances
Switch to the 2D plan view to check walking paths, doorway clearances, and how close a piece sits to outlets, vents, or radiators.
3D view to spot proportion problems
One tap switches to 3D, where you'll immediately see if a tall piece dwarfs the room or a low-profile sofa disappears against the back wall.
Export with dimensions to share
Export a labeled PNG with measurements to send to a partner, or to bring up in-store as a reference when comparing actual options.
How to Check If Furniture Will Fit
- 1
Measure your room
Use a tape measure for length, width, and ceiling height. Note the position of every door, window, vent, outlet, and radiator — these all affect placement.
- 2
Draw the room to scale in Room Sketch 3D
Open the app, start a new project, and draw your room walls. The scale-to-grid feature locks dimensions to the inch (or centimeter).
- 3
Add the furniture you already have
Start with what's staying — your existing bed, TV stand, or accent chair. This shows the piece you're considering in real context, not in an empty room.
- 4
Drop in the new piece using its retailer dimensions
Pull width × depth × height from the product page, then drop a custom-sized item into your plan. Position it where you actually want it.
- 5
Check 2D clearances
In 2D top-down, confirm at least 30 inches of walking space around the piece, doorway clearance of at least 32 inches, and that the piece doesn't block a vent or window.
- 6
Switch to 3D and decide
Tap 3D to see the piece in proportion. If anything looks off — too tall, too dark, blocks the view from the kitchen — try a different size before you buy.
Tips for Accurate Furniture Fit Checks
Measure twice, especially the path in
The biggest cause of returned sofas isn't fit in the room — it's fit through the door, around the stair landing, or up the elevator. Measure every doorway, hallway turn, and tight spot between the truck and the room.
Use the retailer's listed depth, not just width
Sofas vary wildly in depth (32" vs 42" feels nothing alike). A deep sectional that looks fine on width alone can swallow a small living room. Always model both dimensions.
Leave at least 18 inches in front of seating
Coffee tables and ottomans should sit 14–18 inches from the front of a sofa. Less, and people knock their shins. More, and reaching a drink is awkward. Check this in the 2D view before deciding.
Don't forget doorway swing
Doors swing into the room about 32 inches. A piece that technically fits the floor space but blocks the door is unusable. The 2D plan view shows door swings explicitly.
Frequently Asked Questions
How do I know if my couch will fit in my living room?
Draw your living room to scale in Room Sketch 3D, add doors, windows, and existing furniture, then drop in the couch using its exact width × depth × height from the retailer. The 2D view confirms the couch fits with 30+ inches of walking space, and the 3D view shows the proportions in context. Room Sketch 3D is a $9.99 one-time purchase — no subscription — and works on web, iPhone, iPad, and Android.
Do I need exact dimensions to check fit?
Yes — fit checks are only as good as your numbers. Get width, depth, and height from the product page or spec sheet, and measure your room with a tape (not paces). Room Sketch 3D's scale tool lets you enter dimensions to the inch or centimeter so the drawing matches reality.
Can I check fit on my phone before I leave the store?
Yes. Room Sketch 3D works on iPhone, iPad, and Android. Save your room layout when you're at home, then load it on your phone in-store. Drop in the in-store piece's dimensions to confirm it fits before you commit.
How much does Room Sketch 3D cost?
Room Sketch 3D is $9.99 one-time. There is no subscription, no recurring fee, and no in-app upsell. The single purchase unlocks the web app, iOS app, and Android app — all 350+ furniture pieces, 2D and 3D views, exports, and cloud sync included.
What if the furniture isn't in your library?
You can add a custom-sized piece using the retailer's exact dimensions. Width × depth × height is enough — Room Sketch 3D draws the footprint to scale and shows it in 3D. The library has 350+ common pieces, but custom sizing is unlimited.
Is there a guarantee in case the app doesn't work for me?
Yes — Room Sketch 3D comes with a 30-day money-back guarantee. If you decide it's not the right tool for your project, email roomsketch3d@immex.tech for a refund.
