Custom Cut Mirrors Guide — Mirror Cutting Service, Costs & Sizes
Ordering a mirror cut to size is a ten-minute phone call — once you know the four numbers that set the price: thickness, area, edge finish and glass grade. This guide puts a working number on every line of a mirror quote, compares where to get mirrors cut near you, and answers the question behind most searches: who actually cuts mirrors, and what should it cost?
| Thickness | Typical use | Practical max panel | Weight | Cost class |
|---|---|---|---|---|
| 1/8" (3 mm) | Furniture inlays, craft panels, wardrobe door inserts | ≈ 24 × 36 in | 7.5 kg/m² | $ – |
| 3/16" (4 mm)Standard | Standard wall mirrors — the default for bathrooms & hallways | ≈ 36 × 60 in | 10 kg/m² | $$ |
| 1/4" (6 mm) | Large feature walls, gym & dance mirrors, freestanding mirrors | ≈ 48 × 84 in | 15 kg/m² | $$$ |
| 3/8" (10 mm) low-iron | Showroom-grade feature mirrors, no-distortion display walls | ≈ 84 × 130 in | 25 kg/m² | $$$$ |
Every price on this page scales with area and weight, so run your own panel through the Glass Weight Calculator before you call a shop — mirror weight decides delivery fees and whether one person can legally lift it. For a full cut-to-size cost breakdown including edge polishing and toughening, open the Glass Price Calculator, and keep the main calculator on the home page in another tab while you read — every thickness in the matrix above is one preset away.
How Mirror Cutting Works: Scribe, Snap and Edge
A mirror is float glass with a silver coating and protective paint layers on the back — which is why every cut is made on the coated side. The shop scores a single continuous line with a carbide-wheel cutter, the wheel's pressure opens a microscopic fissure in the glass surface, and one firm press "runs" the fissure straight through the sheet. Done right, the process takes seconds and the break follows the score to the millimetre. Done wrong — scored twice, or scored on the silver side — the break wanders and the panel is scrap.
What separates a shop result from a DIY result is the edge. A fresh-cut edge is sharp and carries micro-chips along the score line. Three finishes exist: seamed (edges lightly sanded safe to touch, standard on hidden edges), flat polished (ground and polished to a glossy, safe arris — the default for exposed frameless edges), and beveled (glass ground at 15–45° over a 1/2"–1 1/4" band, producing the prismatic frameless look). Beveling is a separate machine pass, which is why it is priced per linear foot rather than included.

💡 Ordering note: Edges are priced per linear foot, so a 24 × 36 in mirror with all four edges polished carries 10 linear feet of edge — roughly 40% of the whole bill on a small panel. Knowing this, you can leave two edges seamed where they meet a frame and save real money.
Custom Cut Mirror Cost: Every Line Item, Priced
Mirror quotes are not mysterious — they are base glass plus area, plus edge work, plus upgrades, plus a shop minimum. Here is the 2026 US breakdown with real ranges; regional labor costs swing each line by ±20%.
| Cost factor | 2026 US range | What it buys |
|---|---|---|
| Base cut, 4 mm clear mirror | $6 – $10 per sq ft | Straight cut, seamed edge, no tempering. The floor price nearly every glass shop quotes. |
| Polished (flat) edge | +$1 – $3 per linear ft | Removes sharpness and micro-chips. Essential on any exposed edge; invisible cost on framed mirrors. |
| Bevel edge (1/2" – 1 1/4") | +$3 – $8 per linear ft | The prismatic frameless look. Price scales with bevel width — 1" bevels can double the edge line item. |
| 6 mm upgrade | +40% – 70% over 4 mm | Buys flatness on big walls. Under ~30 × 40 in, most people cannot see the difference. |
| Low-iron mirror glass | +30% – 60% | Removes the green cast on edges and brightens the reflection. Only visible where the edge or tint meets a white wall. |
| Tempered mirror | +60% – 120% | Required in some commercial installs; for home use it adds cost and, once cut, it can never be re-cut. |
| Minimum order / shop fee | $25 – $50 flat | Small cuts still pay it. Two tiny jobs at one shop cost less than one job each at two shops. |
⚠ The tipping point: Below roughly 36 × 60 in, upgrading from 4 mm to 6 mm buys almost nothing visible — thickness only affects perceived reflection flatness on large panels, where the sheet itself flexes. Above 48 × 72 in, 6 mm stops being an upgrade and becomes the honest minimum; 4 mm sheets that size visibly "fun-house" on the wall.
Where to Get a Mirror Cut to Size Near You
"Mirror cutting near me" returns four kinds of businesses, and the right one depends on the job, not the distance. The comparison below is what each channel can and cannot do — and the small-print fees that decide the final bill.
| Channel | Polished edges | Bevel | Delivery | Install | Typical minimum | Best for |
|---|---|---|---|---|---|---|
| Local glass shop / mirror glazierMost capable | $25–50 | Large, heavy or beveled work | ||||
| Big-box store (Lowe's, Home Depot) | Often free w/ purchase | Small–medium straight cuts | ||||
| Online cut-to-size retailer | $30–60 | Odd sizes, no local shop | ||||
| Hardware store counter | $5–15 | Craft and repair offcuts |
✅ Do: Call two shops with the same spec and ask for an itemized quote — glass / edges / minimum / delivery. Itemized quotes expose why one "cheap" shop costs more once the $25 minimum and the $40 delivery are added.
❌ Don't: Buy a pre-cut "close enough" mirror for a recessed medicine cabinet niche. Niches are rarely square; a mirror 1/8" oversize either doesn't fit or cracks under install pressure. Cut to the measured niche minus 1/8" total.
Can You Cut a Mirror Yourself? An Honest Answer
For small, frame-hidden pieces — yes. A $12 carbide cutter, a straightedge, cutting oil, gloves and safety glasses turn a 3/16" mirror sheet into a 12 × 18 in shelf insert in ten minutes: score once, firmly, on the coated side, then snap over a dowel edge. What DIY cannot deliver is the finish. Every home cut leaves a sharp seamed edge (sand it), no bevel, and a real failure rate — expect roughly one cracked panel in your first three attempts while you learn the pressure.
The piece is under ~20 × 24 in, the edge hides in a frame, and a cracked attempt costs you $10 of offcut rather than a $90 panel.
The edge is exposed, the panel is large, the mirror is tempered or low-iron, or the piece must fit a niche exactly on the first attempt.
Tempered mirror cannot be cut after tempering — it explodes. Any panel you cannot hold flat on a bench alone is a two-person shop job.
⚠ Safety floor: Mirror shards are glass plus razor-edged silvering — they cut deeper than window glass. Long sleeves, closed shoes, safety glasses, and a broom-and-dustpan (never bare hands on the bench) are non-negotiable, even for a practice piece.
Low-Iron Mirror vs Standard Mirror: Is the Upgrade Visible?
Standard mirror glass carries about 0.08–0.12% iron; low-iron drops below 0.01%. Iron absorbs red light, which is why a standard mirror's edge glows green and its reflection tints slightly cool against pure white. Low-iron (sometimes branded "ultra-clear") renders edges nearly colorless and the reflection neutral. Whether you can see the difference depends entirely on what sits next to the mirror.
Where the Difference Shows — Same Room, Both Mirrors
The verdict pattern: pay the 30–60% premium when the mirror is frameless, meets a white surface, or butts another mirror — skip it inside a frame or against color. For the full optical story (iron content, transmission numbers, aquarium and display use), read the Low-Iron Glass Guide, which covers the same glass in its architectural role.

The mirror inside is often the same; the order around it is not. A framed mirror hides every edge, so it can be ordered seamed on all four sides (free) and cut to loose tolerances — the frame covers a 1/8" miss. A frameless mirror is furniture: all four edges are exposed and finished ($1.50–$8 per foot), corners often get a small arris or radius, and the glass needs 6 mm thickness above a certain size because the panel must hold flat with nothing around it.
Mounting follows the same split. Framed mirrors hang on a standard French cleat or D-rings like heavy artwork. Frameless mirrors use clips, adhesive mastic, or a bottom J-channel plus top clips — and on walls that are not plumb, a shop-bent J-channel is more forgiving than adhesive alone. If your wall is old plaster, mention it when ordering: large adhesive-mounted mirrors on failing plaster are the classic teardown-story setup.
✅ Budget shortcut: A framed mirror with seamed edges and standard 4 mm glass typically lands 35–50% below the identical frameless piece with polished edges and 6 mm glass. If a frame suits the room, the frame is the cheapest "edge finish" money can buy.
⚠ Size note: Above ~48 × 72 in, order frameless mirrors in 6 mm and ask the shop to confirm handling — a panel that size weighs about 50 lb and needs two people or a delivered-and-installed service.
How to Order a Custom Cut Mirror: The 5-Line Phone Script
Shops quote fast when you hand them the spec in their own order. Five lines, in this sequence, get an itemized number on the first call:
"24 by 36, cut to 23 7/8 by 35 7/8 for a niche" — the minus-1/8" total tells them you measured an opening.
"4 mm is fine, it's 24 inches wide" — or ask them: any panel over 30 × 40 exposed, take their 6 mm advice.
"Flat polish on top and both sides, seamed bottom into the channel" — naming the hidden edge shows you know where the cost lives.
"Standard mirror, unless you recommend low-iron for a white wall" — one question, saves a second call.
"What's delivery and handling on a 25-pound panel?" — weight decides whether this is a pickup job or a two-person install.
💡 Tolerance rule: inside a niche or frame, order glass 1/8" smaller than the opening total (1/16" per side). For a frameless wall mirror cut to your layout line, the shop cuts exact to your numbers — so measure twice, because glass cannot be stretched and neither can a deadline.
Shipping & Handling: How Mirrors Travel Without Dying
A mirror is the most fragile thing ordinary freight moves, and the packaging rules exist for a reason. Shop-local pieces over roughly 36 × 48 in ride A-frame racks with edge protectors; anything shipped rides in a wooden crate, glass separated by foam, marked fragile on two faces. Weight is the hidden variable: a 4 mm mirror is 10 kg/m², so a 24 × 36 in panel is ~12 kg (26 lb) before the crate adds another 5–8 lb — which is why shipping a "small" mirror often costs more than the mirror.
- • Anything over ~48 in on a side usually leaves parcel networks and moves by freight or the shop's own van.
- • Mirror shipments are excluded from some standard damage cover — check the shop's breakage policy in writing before paying.
- • Reputable shippers guarantee on-glass-arrival: sign "subject to inspection" or note any damage before the driver leaves.
- • Carry on edge, never flat — a panel carried flat snaps under its own flex.
- • In a car: A-frame or mattress leaned at 60–75°, edges on foam, seatbelt strap over the face (not the edge).
- • Over 50 lb / 36 × 48 in: two adults minimum, planned route, no doorframe surprises.
Get the exact number first: the Glass Weight Calculator converts any mirror size and thickness to kg or lbs, and the Glass Price Calculator estimates the full cut-to-size bill — glass, edges, holes and toughening — before you compare it to the shop's quote. The home page calculator gives the same numbers in one screen, and every tool on the site is listed in the calculators hub.
Custom Mirror FAQ
Who cuts mirrors to size?▼
Three kinds of businesses cut mirrors: dedicated glass and mirror shops (the most capable — they polish edges, bevel and deliver), the glass counters at big-box home improvement stores like Lowe's and Home Depot (good for straightforward straight cuts on 3/16" and 1/4" mirror sheet), and online cut-to-size retailers who ship crated. The trade name for the person doing the work is a glazier; searching "mirror glazier near me" usually surfaces the shops with full edge-finishing equipment rather than just a cutting table.
Where can I get a mirror cut to size near me?▼
Search "mirror cutting service near me" or "glass and mirror shop" plus your city, and call two or three with your dimensions ready — width × height, thickness guess, and where the mirror will be mounted. Ask three questions on the call: can they polish or bevel the edges, do they deliver or install pieces above 40 lb, and what is the turnaround. A shop that answers all three crisply is a shop that does this work every day. For small projects, the big-box glass counter is usually the fastest and cheapest route.
How much does a custom cut mirror cost?▼
A standard 4 mm mirror cut to size runs $6–$10 per square foot in most US metro areas, so a common 24 × 36 in bath mirror (6 sq ft) lands around $36–$60 plus a $25–$50 shop minimum. Add $1–$3 per linear foot for polished edges, $3–$8 per foot for bevels, and 40–70% more for 6 mm thickness. Low-iron mirror glass adds 30–60%; tempering adds 60–120%. Delivery or installation of large panels is typically quoted separately, often $50–$150 depending on weight and stairs.
Can you cut a mirror at home?▼
Yes, on small and non-critical pieces — with the right kit: a carbide-wheel glass cutter, straightedge, cutting oil, gloves and eye protection. The process is scribe-and-break: one firm, continuous score on the coated side, then snap. What you cannot do at home is polish or bevel edges safely, temper glass, or cut large panels without cracking risk — every DIY cut leaves a sharp, seamed edge that needs sanding and is best hidden in a frame. For anything wall-mounted above a sofa, or any panel over ~20 × 24 in, a shop's $10 edge polish is cheaper than one laceration.
Does Lowe's cut mirrors to size?▼
Most Lowe's and Home Depot stores cut mirror sheet to basic sizes at the glass counter, often free or for a small fee when you buy the mirror stock there. The service is straight cuts only — no beveling, no polishing beyond a safe-touch seam, and thickness is limited to the sheet stock they carry (usually 3/16" and 1/4"). Availability varies by location, so call ahead with your dimensions. For anything with shaped corners, bevels or holes, a dedicated glass shop is the right tool.
What is the smallest mirror that can be custom cut?▼
Practically, about 2 × 2 inches — below that, mirrors flex out of square during the snap and shops decline the job. Most shops set a minimum billable area or a $25–$50 minimum order fee rather than a physical minimum, so a 4 × 6 in craft mirror is cuttable but rarely economical. If you need several small pieces, ask to have them all cut from one sheet in a single setup; the per-piece price drops sharply because setup, not cutting, is most of the labor.
Why does my mirror have a green edge, and can that be fixed?▼
The green tint on the polished edge is iron in standard soda-lime float glass — roughly 0.08–0.12% iron content absorbs red light and reads green on a thick edge. It is not a defect and cannot be polished away. The only fix is ordering low-iron mirror glass, which drops iron content below 0.01% and renders edges nearly colorless. The difference matters most on frameless mirrors against white walls or anywhere two mirrors meet at a joint, where a green seam line would otherwise show.
