Three Ranges That Cover Most Builds

Eighteen to Twenty Millimeters

This slim band works for compact stations.
Picture a writing perch at one ten by sixty.
Hardwood oak or maple stands tall at this depth.
Run a full apron round the edge or a wall cleat along the rear.
Keep spans under one hundred centimeters if legs support only corners.
Clamp arms still grip when the pad spreads wide.
I keep a small oak desk at this size and it stays flat after five quiet years.

Twenty Two to Twenty Six Millimeters

Call this the goldilocks group.
Sit stand frames thrive here.
Lift motors welcome the moderate mass.
Unsupported spans sail to one eighty in oak with legs placed with sense.
Edge comfort grows.
You may run a six millimeter round and keep a crisp line.
Arms clamp with zero dent in walnut.
My daily worktop falls in this band.
Dual monitors perch on arms yet the keyboard never rattles.

Twenty Eight to Forty Millimeters

Now you enter the heavy crew.
Think executive office or long studio bench.
Visual weight grounds the piece.
Long spans stretch to two eighty in oak if legs sit well inboard.
Heft climbs quick so measure door width before final glue.
Deep chamfers and full bullnose shapes shine here.
A walnut music desk I built at thirty two millimeters whispers authority each time a chord rings.

Wood Species Shift the Math

Oak and maple act like steel in desk scale.
They refuse to bow under common loads.
Walnut follows close yet dents a hint faster.
Pine bends with ease, so add three to six millimeters or sneak a stretcher under.
Fir shares that story.
Bamboo panels mimic mid grade hardwoods with fresh eco flair.
Plywood mainly Baltic birch stays flat and strong at modest depth since layers cross brace each other.

Use species strength charts if you crave numbers.
Still feel counts.
Pick wood that calls to your eyes and nose then size with margin.

Span and Support Decide True Strength

Span means clear length between supports.
Grab a tape and mark those points before you cut lumber.

Guide for oak with normal office gear:

• Eighteen to twenty millimeters holds flat to one meter.
• Twenty two to twenty five rests steady to one point eight meters.
• Twenty eight to thirty two sits calm to two point eight meters.

Pine steps back a shade.
Plywood steps forward a touch.

Support style alters the game.
A full apron acts like a spine.
One center stretcher lifts a wide grin out of any sag.
Wide metal plates deliver load across grain and prevent dents.
Always spread weight with intention.

Height Adjustable Frames and Top Mass

Motors list a lift limit that covers top plus gear.
Count every gram before install.

For reference:

• Twenty four millimeter oak at one sixty by seventy five tips the scale near twenty eight kilograms after finish.
• Walnut of same size drops two kilos.
• Maple adds a hair.

Many middle frames lift one hundred twenty kilos.
Subtract the top weight to see free capacity.
Keep cables slack so motors treat the desk kindly.

Wide plates matter.
Tiny corner brackets create bounce and leave bruises inside fibers.

Monitor Arms Need Bite and Spread

A slim panel accepts an arm if you feed it care.

• Hard oak at eighteen to twenty millimeters clasps fine with a broad pad.
• Soft pine likes a hardwood backing block inside the clamp.
• Twenty two to twenty five in walnut laughs at the load.
• Twenty eight plus invites through bolts with grommets.

Keep arms near frame lines for extra grace.
Your wrist will thank you during each shuffle.

Edge Profiles Shape Comfort

Edge feel lives under palms all day.

• Eighteen to twenty wants a small round maybe three millimeters.
• Twenty two to twenty five enjoys six to eight.
• Twenty eight plus welcomes deep chamfer or gentle bullnose.

My favorite combo is a light three millimeter break on both faces of a twenty four millimeter oak slab.
It feels smooth yet crisp.

Tricks that Help a Thin Top Perform

Wood costs money and weight taxes motors.
You can fake depth with smart moves.

• Drop edge. Glue a thirty millimeter strip under front and sides of an eighteen millimeter field. Grain wraps through a miter so eyes read thick.
• Hidden battens. Bolt hardwood bars near front and rear underside. Slots allow seasonal swell.
• Steel angle. A twenty five by twenty five bar under the back edge stiffens like magic and hides under shadow.
• Torsion shell. Two thin skins over a grid yield a feather light but rigid table.
• Classic apron. Sixty millimeter rails round the perimeter and lift any slim panel to stone status.

Pick one based on style and tool set.
