The sizes Home Depot stocks most, from 3,344 listings, 1,667 with a standard code · September 2026 · CSV / JSON

Pick a room and a window type to see each standard size drawn at its true size next to a 6 ft person, with the width and height written on the drawing. Sizes are ranked by how many Home Depot listings carry them, so the first chip is the most-stocked at Home Depot for that filter.

3030 sliding: unit 35½ × 35½ in, rough opening 36 × 36 in · 53 Home Depot listings

Replacing a bedroom window: usually exempt from egress

A slider opens only about half its width.

New opening or a change of style (a hung window or slider where a casement was): fails. A 3030 sliding falls short of IRC R310's minimums (5.7 sq ft clear opening, at least 24″ high and 20″ wide) even with no frame deducted, so check a larger size or a casement if the style changes.

Verify with your local code official.

How window size codes work

A size code is the rough opening, the framed hole in the wall, written width first. Each half is feet then inches: 3050 means 3′0″ wide by 5′0″ tall, a 36 × 60 inch opening.

Rough opening (36 × 60 in): what the code names and what a framer builds.
Unit size (35½ × 59½ in): the outside of the window frame, normally half an inch under the opening each way so the unit can be shimmed level.
Glass size: smaller again, by the width of the frame and sash. It varies by brand and is not part of the code.

Codes only carry 0 to 9 inches per side, so an opening like 3′10″ has no four-digit code. Replacement (insert) windows are sized to fit an existing frame and often land on sizes like 37⅝ × 56⅞ that no code expresses; this page shows those at their exact size, labelled “replacement size, no standard code”, and never rounds them to a code.

Sizes by room

Rooms are rules, not lists: each size is tested against the room's sill height and size limits below. The drawing shows the most-stocked size at Home Depot that fits each room's rules.

Bedroom

Any window that opens, at a 24″ sill. Each size's egress verdict is shown when you pick it; a like-for-like replacement is usually exempt.

110 sizes fit a bedroom's rules. Most-stocked at Home Depot: 3030 sliding, 4030 sliding, 4040 sliding.

Bathroom

36″ tall or less, for a 54″ privacy sill.

53 sizes fit a bathroom's rules. Most-stocked at Home Depot: 3030 sliding, 4030 sliding, 2030 single-hung.

Kitchen

48″ tall or less and opens, over a counter at a 42″ sill.

76 sizes fit a kitchen's rules. Most-stocked at Home Depot: 3030 sliding, 4030 sliding, 4040 sliding.

Living room

Picture windows, or units 47½″ wide and up, at a 18″ sill.

46 sizes fit a living room's rules. Most-stocked at Home Depot: 4040 picture, 4030 sliding, 4040 sliding.

Replacing a window in the same opening? IRC R310.5 (R310.2.5 in the 2018 code) exempts a replacement from the egress size and sill-height rules when it is the manufacturer's largest standard size that fits the existing opening and is the same operating style, or a style that opens at least as much. For a new opening or a change of style, bedroom egress uses IRC R310: at least 5.7 sq ft of clear opening (5 sq ft at a grade-floor opening), 24 in high, 20 in wide, with the sill no higher than 44 in. Hung windows open about half their height and sliders about half their width. A size “passes” here only if it still clears the minimums after taking 4 in off its opening width and height for the frame; it “fails” only if it falls short with no frame at all. Anything between is borderline: check the manufacturer's clear-opening spec. Verify with your local code official.

Methodology and limits

The source is Home Depot's public product sitemaps, fetched 2026-09-07: 4,320,547 product URLs scanned, 3,818 of them window listings. Sizes and types are read from each listing's URL, because product pages block automated access.

3,344 listings used, grouped into 673 distinct sizes.
1,672 standard: a unit half an inch under a whole-inch rough opening. 1,667 of them carry a four-digit code.
1,011 replacement sizes: unit sizes that are not half an inch under a whole-inch opening, shown exactly and given no code.
661 unconfirmed: listed in whole inches by brands whose own published size tables do not settle whether that figure is the unit or the rough opening. Kept apart rather than guessed, because a wrong guess shifts the code by half an inch.
Left out: 434 listings with no size in the URL, 39 hopper, bay and bow listings, and 1 with an implausible size.

SKU counts describe what Home Depot lists, not what is installed. A size with many listings is one Home Depot carries in many brands, colours and glass options. The dataset has no prices, no other retailers and no custom sizes. Room rules and egress checks are geometry on the listed size, not a code review. Verify with your local code official.

Frequently asked questions

What size is a 3050 window?

A 3050 window has a 36 × 60 inch rough opening (3′0″ wide by 5′0″ tall). The window unit itself is half an inch smaller each way, 35½ × 59½ inches, so it fits the opening with room to shim and level.

How do window size codes work?

A four-digit size code is the rough opening, width first: feet then inches of the width, then feet then inches of the height. The unit is normally half an inch smaller than the rough opening in each direction. Codes only express whole inches from 0 to 9, so an opening such as 3′10″ has no four-digit code.

Is a 3050 single-hung window big enough for bedroom egress?

Under IRC R310 an egress opening needs at least 5.7 sq ft of clear opening (5 sq ft at a grade-floor opening), 24 inches of clear height, 20 inches of clear width and a sill no higher than 44 inches. A 3050 single-hung is borderline: check the manufacturer's clear-opening spec. A 3050 casement passes on size, because it opens across its full size. That test applies to a new opening or a change of style; a like-for-like replacement in the same opening is usually exempt. Verify with your local code official.

Does a replacement bedroom window have to meet egress?

Usually not, if the opening stays the same. IRC R310.5 (R310.2.5 in the 2018 code) exempts a replacement from the egress size and sill-height rules when it is the manufacturer's largest standard size that fits the existing opening and is the same operating style, or a style that opens at least as much. The exemption does not apply to a change of occupancy, and some jurisdictions add conditions, such as an unmodified rough opening. Verify with your local code official.

Which window sizes does Home Depot stock most?

By number of Home Depot listings, the most-stocked coded standard sizes are 4040 picture (63 listings), 3030 sliding (53 listings), 4030 sliding (53 listings), 4040 sliding (53 listings), 5040 sliding (53 listings). Listing counts describe what Home Depot lists, not what is installed.

What is the difference between rough opening and unit size?

The rough opening is the framed hole in the wall. The unit size is the outside of the window frame, normally half an inch smaller each way. Replacement and insert windows are sized to an existing opening instead, so their sizes often have no standard code.

Can I use this window size data?

What does your size cost installed?
