Quality in fitted woodwork is mostly measurable, which means you do not have to take anyone's word for it. Eight checks, a steel rule and a phone torch will tell you more in ten minutes than a conversation will. The one thing to know first is that India publishes no consumer standard for this, so the number has to be in your agreement.
Is There an Indian Standard for Furniture Fitting Tolerance?
Not a published consumer-facing one for installed modular furniture. There are Indian Standards for the materials, IS 303 and IS 710 for plywood among them, but the fit and finish of an installed unit is governed by whatever your agreement says, and most agreements say nothing.
The nearest published reference is the Architectural Woodwork Institute standard used in North America, which specifies a 3.2 mm gap with a permitted variation of plus or minus 0.8 mm at premium grade, 1.6 mm at custom grade and 2.4 mm at economy grade. It is not binding here and we are not claiming it is. It is useful because it demonstrates that the industry elsewhere treats this as a number rather than an opinion.
The practical consequence for a homeowner in Bengaluru is simple. Ask for the reveal gap to be stated in millimetres in the quotation. A firm that will commit to a number is a firm that intends to hit it, and you then have something to measure against rather than an argument about whether something "looks fine".
What Are the Eight Checks?
| Check | How | What good looks like |
|---|---|---|
| 1. Reveal gaps | Steel rule at top, middle and bottom of each gap | Consistent along the whole run. The number matters less than the consistency |
| 2. Panel flatness | Straight edge down and across each shutter | Touches along its length. No daylight in the middle |
| 3. Drawer face alignment | Sight across a bank of closed drawers | Faces form one plane, gaps equal between them |
| 4. Edge banding | Run a thumbnail along every edge, including hidden ones | No lip you can catch, and nothing raw at the back or underside |
| 5. Hinge load test | Open a door fully and apply gentle downward pressure | No movement at the hinge plate, no creak from the carcass |
| 6. Loft shutter droop | Close it and sight along the bottom edge | Parallel to the unit below, not tapering |
| 7. Carcass square | Measure both diagonals inside an open bay | Equal. Unequal means the box is racked |
| 8. Soft-close consistency | Close every door and drawer from the same position | All behave the same. One that slams means a failed or missing damper |
Do these before the final payment, not after. Every one of them is cheap to correct while the fitter is still on site and awkward afterwards.
What Does a Bad Reveal Gap Actually Look Like?
Not a gap that is wide. A gap that changes. Human vision is poor at judging absolute distance and very good at detecting a line that is not parallel, which is why an uneven reveal reads as bad workmanship even to someone who could not say why.
Measure each gap at the top, the middle and the bottom. A gap that is consistent along its height is correct even if it is wider than you would like. A gap that tapers visibly from top to bottom is a dropped door, a racked carcass, or a shutter that is not square.
Then compare gaps across the run. Several doors with slightly different gaps read worse than all of them having the same slightly-too-wide gap. Consistency across the run is what the eye actually judges.
Most taper is correctable by hinge adjustment while the fitter is there. That is precisely why this check belongs before the final payment.
Why Is the Thumbnail Test the Most Important One?
Because edge banding is the single biggest determinant of how long a unit survives in Indian conditions, and it is the easiest thing to skimp on invisibly.
Run a thumbnail along every edge. A properly applied band is flush; you should feel the transition but not catch on it. A lip you can catch means the band is proud and will chip, and a chip is an opening for moisture.
Then check the edges nobody sees: the back edge of a shelf, the underside of a base panel, the inside edge of a side panel. Raw board there is the most common corner cut in the industry and the one that costs you most, because moisture enters through edges far faster than through faces.
Ask what banding thickness was used. A thicker band resists the chipping that starts the whole failure sequence, and "edge banded" without a thickness is not a specification.
How Do You Check a Carcass Is Square?
Measure the two diagonals inside an open bay, corner to corner. If they are equal the bay is square. If they differ, the box is a parallelogram and no amount of hinge adjustment will make the shutters sit right permanently.
This is the check that separates a hardware problem from a structural one. A single misaligned door is usually a hinge. A whole run of doors leaning the same way, with unequal diagonals behind them, is the carcass.
In a newly installed unit an out-of-square carcass means it was not levelled properly against the wall, which is an installation fault and should be corrected rather than accepted. In an older unit it usually means the box has moved, which is a different and larger conversation covered in our five-point carcass check.
What Should You Not Judge Quality On?
Three things that feel like quality signals and are not.
How it looks in photographs. Every finished unit photographs well at the right angle in the right light. Quality shows in the lines and the junctions, which is exactly what a photograph flattens.
The brand name on the hardware. A brand is not a specification. The same manufacturer sells ranges at very different performance points, and two branded hinges on a visible cabinet with local hinges elsewhere is a known cost lever. Ask for the model number and count, not the brand.
How quickly it was finished. Speed on site usually means the manufacturing was done properly off site, which is good, or that finishing was rushed, which is not. Speed alone tells you nothing; the eight checks do.
When Exactly Should You Run These?
Before the final payment and while the fitter is still in the building. That is the only moment when every one of these is cheap to fix.
A practical sequence: walk the job with the person who installed it, run the eight checks together, agree what will be corrected, and settle the final payment after the corrections rather than before. None of this is adversarial and a competent fitter will expect it; alignment is the last step of their own job.
In a Bengaluru apartment there is a scheduling reason too. Once the team has left and the society work permit has closed, bringing them back means fresh gate registration, another lift booking and another day in the association's calendar. Correcting on the day is easier for everyone.
Frequently Asked Questions
Is there an Indian standard for furniture fitting tolerance?
Not a published consumer-facing one for installed modular furniture. Indian Standards exist for materials, such as IS 303 and IS 710 for plywood, but fit and finish is governed by whatever your agreement says. The practical response is to ask for the reveal gap in millimetres in the quotation.
What is an acceptable gap between wardrobe doors?
Consistency matters more than the number. The nearest published reference is the Architectural Woodwork Institute standard used in North America, which specifies 3.2 mm with variation of plus or minus 0.8 mm at premium grade. It is not binding in India, but it shows the industry elsewhere treats this as a measurable number.
How do I tell a bad reveal gap from an acceptable one?
Measure each gap at top, middle and bottom. A gap consistent along its height is correct even if wider than you would like. A gap that tapers is a dropped door, a racked carcass or a shutter that is not square. Then compare gaps across the run, because the eye judges consistency rather than absolute width.
What is the thumbnail test on edge banding?
Run a thumbnail along every edge, including the back edge of shelves and the underside of base panels. A properly applied band is flush; a lip you can catch will chip, and a chip is an opening for moisture. Raw board on hidden edges is the most common invisible corner cut.
How do I check whether a carcass is square?
Measure the two diagonals inside an open bay, corner to corner. Equal diagonals mean the bay is square. Unequal means the box is a parallelogram, and no amount of hinge adjustment will hold the shutters right permanently. In a new installation that is a levelling fault and should be corrected.
Should I judge quality by the hardware brand?
No. A brand is not a specification, because the same manufacturer sells ranges at very different performance points. Ask for the model number and the count per unit rather than the brand name, and check that what was fitted matches what was quoted.
When should I run these checks?
Before the final payment and while the fitter is still in the building. Every one of them is cheap to correct on the day and awkward afterwards. Walk the job together, agree what will be corrected, and settle the final payment after the corrections rather than before.
Is it unreasonable to inspect the work this closely?
No, and a competent fitter expects it. Alignment is the last step of their own job, so running the checks together is simply finishing it. In a Bengaluru apartment there is also a practical reason: once the team leaves and the work permit closes, returning needs fresh gate registration and another lift booking.
