Choosing a custom mirror sounds simple until the use case enters the conversation. A bathroom vanity mirror follows different sizing rules than a full-wall home gym install, and a statement entryway piece is governed by a third set of proportions altogether. The right size, edge style, and mounting height depend on the room's role, the surrounding finishes, and how the homeowner or designer wants the space to read. This guide walks three primary clusters — bathroom vanity, home gym and fitness studio, and entryway / hallway / dressing-room — plus the cross-cuts that govern all three. American Glass & Glazing fabricates and installs custom mirror across the Grand Strand for homeowners, interior designers, and home-gym and studio owners.

The vanity-ratio rule is the starting point for any custom mirror over a bathroom vanity. The mirror should be 80–100% of the vanity tabletop width and never wider than the vanity — most homeowners and designers size the mirror 2–4 inches narrower on each side. On standard vanity widths (24, 30, 36, 48, 60, or 72 inches), the math runs predictable: a 36" vanity pairs with a roughly 28–34" mirror; a 60" vanity pairs with a 52–58" mirror or a vanity-spanning custom cut.
Mirror height typically lands between 28 and 36 inches, with ceiling height and lighting placement driving the call. Mount the mirror 5 to 10 inches above the sink or the highest point of the faucet.
Single-vanity bathrooms take one centered mirror. Double-vanity layouts split into a real decision: a single vanity-spanning mirror delivers a unified look and bounces more reflected light around the room, while two centered mirrors — one above each sink — deliver symmetry and integrate cleanly with sconces flanking each basin. If the bathroom leans designer-spec or basin spacing is tight, the vanity-spanning cut usually wins; if sconces are the architectural feature, matched-pair frames the lighting better.
Edge work, frame style, and lighting integration round out the decision. Polished, beveled, or pencil edges suit most vanity mirror; frameless reads modern, framed reads transitional. Sconces flank the mirror or sit between matched pair, overhead lighting frees up width, and backlit LED-integrated mirror is a designer-spec choice. For humidity-heavy installs, AGG specs copper-free silver backing to resist edge-corrosion near showers, with antifog coating as an optional upgrade. ADA-compliant tilt-frame work for accessible primary baths cross-references Commercial Mirror Installations & Repairs Myrtle Beach, SC. Custom-cut work handles angled walls, sloped ceilings, and post-tile dimensions where catalog won't fit.
Form-checking is the design driver for any custom mirror in a gym. A single homeowner gym mirror commonly starts at 48" wide × 72" tall, but serious lifters and technique-driven training favor a full-wall install — typically 6 to 8 feet tall floor-mounted, sized to the wall span. Longer runs break into multi-piece panels (typically 5- or 8-foot sections) for handling and truer per-panel reflection. Dance studios run full-wall mirror from roughly 12 inches above the floor to ceiling for ballet-bar work; yoga studios often pick one-wall over two-wall for a calmer aesthetic; martial-arts and boxing studios add shock-resistant safety backing and baseboard protection. Ballet-bar integration requires structural blocking behind the mirror — coordinate at site measure.
Safety spec is non-negotiable on full-wall scope. AGG specifies 1/4" tempered safety mirror for any full-wall gym, dance, or yoga install — and any mirror over 6 feet tall. Tempered glass is heat-treated to crumble into small pebble-like pieces on impact rather than sharp shards, and it pairs with shock-resistant safety backing that holds the broken glass against the wall if the mirror is struck. Standard 1/4" plate mirror is fine for vanity-scale residential work; full-wall scope is the threshold where the tempered upgrade becomes the locked spec.
Install method matches the spec. A full-wall mirror is set with J-channel (J-mold) at top and bottom + mirror mastic adhesive + mechanical clip backup — mastic alone is not code-compliant for full-wall behind drywall. Durable rubber or wooden baseboard along the bottom edge protects the mirror from free-weight contact; AGG installs the mirror, baseboard coordinates with the contractor. Keep the glass a safe distance from outside wall corners and doors that swing toward the wall. For gym-chain rollouts, hospitality fitness amenities, and multi-property scope, see Commercial Mirror Installations & Repairs Myrtle Beach, SC — that page covers tempered safety to ANSI Z97.1 spec.
A custom mirror in the entryway is part decorative, part functional — it reflects light, expands the visual footprint, and gives anyone walking out the door a final sightline check. Over a console table, bench, or credenza, the mirror should run 50–75% of the furniture's width — a 60" console pairs with a roughly 30–45" mirror — mounted 4 to 6 inches above the furniture top. For a standalone wall-hung mirror, the hanging-height rule places the mirror's vertical center at 57 to 65 inches above the finished floor (eye-level).
Round mirrors in the entryway run 24" to 36" for most homes, with 36" to 48"+ as the statement size for grand entries. Shape changes how the mirror reads: round and oval soften narrow entries, rectangular and arched forms expand narrow corridors and tall walls, and an arched silhouette reads as architectural. If the entry is grand, lean toward an oversized statement piece; if the space is narrow or eclectic, a layered gallery of smaller mirrors usually outperforms a single oversized piece.
Closet and dressing-room full-length is its own decision: door-mounted vs. wall-mounted. Door-mounted saves wall space but adds weight to the closet door; wall-mounted is the cleaner install and pairs with built-in millwork. Full-length runs 18–24 inches wide × 60–72 inches tall at minimum. Decorative tier work — beveled 1/2"–3/4" chamfers, antique or smoked finishes, mitered 45° glass-to-glass joints — lives more naturally here than in a vanity bathroom. For related lifestyle treatment, see the sibling guide Custom Glass Transforms Light and Space.
Across all three clusters, the same four decision-cuts repeat — use this as the at-a-glance framework for any custom mirror project.

AGG measures, fabricates, and installs every custom mirror in-house — full-wall, gym, dance studio, and large vanity scope all run through the AGG shop, with no commodity cut-and-ship on full-wall jobs. Site measure happens in the field, edge work and backing run through the shop, and the install crew sets the mirror with the right method: J-channel and mastic for full-wall, mirror clips for vanity, French cleat for heavy decorative work, or standoffs for a floating look. Designers, decorators, cabinet shops, and contractors send CAD files, shop drawings, or paper templates — AGG works directly with all four.
The 4-step process runs Reach Out → Free Consultation & Custom Quote → Site Measure & Schedule → Professional Installation, tailored to mirror work: virtual photo-based for stock vanity quotes, in-home for full-wall and custom-shape installs, and designer-CAD-coordinated where a designer or contractor leads the spec. AGG carries an SC unlimited general contractor license (#124400). Typical lead time runs 5 to 10 days from approved measure to install; mitered statement work and full-wall gym installs run longer. Per-job pricing depends on wall span, mirror type, edge work, backing, and install method — see Custom Cut Mirror Installations Myrtle Beach, SC for typical project ranges by tier.
Q1. What size mirror should I choose for a bathroom vanity?
A bathroom vanity mirror should be 80–100% of the vanity tabletop width, never wider than the vanity — most homeowners size it 2–4 inches narrower on each side. Mirror height typically runs 28–36 inches, mounted 5–10 inches above the sink or the highest part of the faucet.

Q2. Do I need tempered safety mirror for a home gym wall?
Yes for full-wall installs and any mirror over 6 feet tall. AGG specifies 1/4" tempered safety mirror for any full-wall gym, dance, yoga, or martial-arts install — heat-treated to crumble into small pebble-like pieces on impact rather than sharp shards, paired with shock-resistant safety backing that holds the broken glass against the wall. Standard 1/4" plate is fine for vanity-scale residential work. Commercial-chain gym scope adds ANSI Z97.1 / CPSC 16 CFR 1201 safety glazing compliance.

Q3. How big should an entryway or over-console mirror be?
Over a console table or bench, the mirror should be 50–75% of the furniture's width and mounted 4–6 inches above it. For a standalone entryway statement, hang the mirror with its vertical center at 57–65 inches above the floor (eye-level rule). Round mirrors typically run 24–36 inches; statement size starts at 36" and up.

Q4. Should I use a single mirror or two mirrors over a double vanity?
Both work. A single vanity-spanning mirror creates a unified look and reflects more light around the room. Two centered mirrors — one above each sink — deliver symmetry and integrate cleanly with sconces flanking each basin. The decision is design intent, not a right answer; AGG cuts custom dimensions for either approach.
Q5. What edge style should I choose — polished, beveled, or mitered?
Polished is the smooth modern flat or rounded edge included on most jobs. Beveled is a decorative chamfer 1/2"–3/4" wide — the classic luxury look for bathroom and entryway. Pencil edge is a softly rounded modern alternative. Ogee (S-curve) and mitered (45° glass-to-glass joint) are designer-spec premium options. AGG fabricates all five.
