Tape measure in one hand, phone in the other, staring at the empty corner where a king should go?
Choosing a Nectar king feels simple until you see three very different kings staring back. You want the exact dimensions of nectar king size mattress without digging through size charts, plus a clear answer on Standard versus California versus Split.
This guide gives you both.
You will get fast numbers in inches and cm, room and sheet rules that save headaches, and a simple way to match your height and sleep setup to the right king. No guesswork, no returns drama.
The short version?
All Nectar kings sleep big, but they are shaped for different bodies and rooms. Pick by height and setup, not by name.
Dimensions of Nectar King Size Mattress at a Glance
So what are the Nectar king mattress dimensions in real numbers? Nectar lists three king options, and two share the same footprint.
A Standard King is wide and familiar. A California King trades width for length. A Split King is two Twin XL mattresses pushed together to make a king.
| Nectar King Type | Dimensions in Inches | Dimensions in Cm | Total Footprint |
|---|---|---|---|
| Standard King | 76 x 80 inches | 193.04 x 203.2 cm | Wide rectangle for couples |
| California King | 72 x 84 inches | 182.88 x 213.36 cm | Narrower and 4 inches longer |
| Split King | Two Twin XL at 38 x 80 inches each, 76 x 80 inches combined | 193.04 x 203.2 cm combined | Same footprint as Standard King |
Standard King at 76 x 80 inches is the width leader. It gives couples, midnight migrating toddlers, and boundary ignoring dogs the most side to side room.
California King at 72 x 84 inches is the length leader. It runs 4 inches narrower and 4 inches longer than Standard, which matters if your heels hit the edge.
Split King is the flexible option. Two 38 x 80 inch Twin XL halves equal 76 x 80 inches together, so the floor footprint matches Standard while each side moves alone.
Which Nectar King Is Right for You? Take The Short Quiz Below
Still torn between the three? Height, partner setup, room shape, and adjustable base plans settle this faster than any spec sheet. Answer a few quick questions below to match your situation to the right Nectar king in under a minute.
How tall is the tallest person sleeping on it?
Do you share the bed with a partner?
Do you want an adjustable base?
Independent head and foot recline, now or later.
Do you and your partner sleep differently?
Different firmness, very different schedules, or one light sleeper next to a mover.
What shape is your bedroom?
Your body weight?
Optional, and it fine-tunes the model tip, not the size.
That click is handy once you know your king type, because Nectar pricing changes often and a live deal is almost always running.
Standard King: Built for Shared Width
Who fits a Standard Nectar king size mattress best? Couples who stretch out, plus anyone sharing with a small child or a pet.
Nectar describes it as the pick for couples who stretch out. That tracks, because those extra 4 inches over a Cal King land right where elbows and paws end up.
Think parking lot, not runway. The Standard gives you wider spaces.
Nectar suggests rooms from 13 x 13 ft up to 13 x 19 ft for a Standard King. That leaves walking room on three sides without playing furniture Tetris.
If you and your partner are both under 6 ft and argue more about width than length, this is usually your answer.
Bedding stays simple too. Standard king sheets and blankets fit without a special search.
California King: Built for Tall Sleepers and Long Rooms
When does the Nectar California King win? When length beats width.
The Nectar Cal King measures 72 x 84 inches. That is 4 inches narrower and 4 inches longer than Standard, same surface area class in a different shape.
Nectar points this shape at individuals and couples taller than 6 ft, plus pet parents who need extra foot room. If you wake up with heels on the edge, those 4 inches can feel like a mile.
Long and narrow rooms like it too. Nectar suggests 10 x 12 ft and up for a Cal King, in long narrow layouts up to 13 x 19 ft.
Picture a bowling lane versus a dance floor. The Cal King is the lane.
One catch to plan for now. Cal King does not use regular king sheets, so you will need Cal King specific bedding.
If you sleep stretched out, if you’re taller than 6 ft 2 inches, or your bedroom runs long rather than square, the Cal King often fits better than extra width you will never use.
Split King: Built for Adjustable Bases and Different Sleepers
What is a Nectar split king, exactly? It is two independent Twin XL mattresses, each 38 x 80 inches, that combine to 76 x 80 inches.
So the footprint matches a Standard King. The sleep experience does not.
Each half pairs with an adjustable base so each partner sets a separate head and foot position. With two separate mattresses, partners can even run different firmness feels on each side.
Light sleepers tend to like this setup. Nectar lists it as the best motion isolation of the three, because movement stays on one Twin XL instead of rolling across one big surface.
Basically separate bedrooms without the hallway commute.
The common friction is the center gap. Two halves can drift or show a seam, especially on a flat frame without a connector.
We cover the fix below. Just know going in that if you cuddle in the middle all night, a single piece king feels more seamless.
Standard vs California vs Split King: Side by Side
Choosing by vibe is fun. Choosing by facts is better. Here is how the three Nectar king types compare where it counts.
| Decision Point | Standard King | California King | Split King |
|---|---|---|---|
| Dimensions | 76 x 80 inches | 72 x 84 inches | Two 38 x 80 inch Twin XL |
| Best for | Couples who want width, kids, pets | Sleepers taller than 6 ft, long narrow rooms | Adjustable bases, different schedules, light sleepers |
| Motion isolation | Shared surface | Shared surface | Strongest of the three, split surface |
| Bedding | Standard king bedding | Needs Cal King bedding | Needs Twin XL sheets or split king bedding |
| Room shape | Square to large, 13 x 13 ft to 13 x 19 ft | Long and narrow, 10 x 12 ft to 13 x 19 ft | Same footprint as Standard King |
Is a California King bigger than a King? Not bigger in any useful sense.
A Cal King is longer but narrower. A Standard King is wider but shorter. You pick a layout, not an upgrade.
What is the difference between a split king and a king? Construction and movement.
A Standard King is one mattress. A split king is two Twin XL mattresses that equal a king footprint but recline, flex, and isolate motion independently.
Will It Fit in Your Room, Frame and Sheets?
Measurements save door frames and weekend plans. Here is how to make the Nectar king mattress dimensions work in your actual bedroom.
Start with floor space. Nectar suggests 13 x 13 ft up to 13 x 19 ft for a Standard King, with the same footprint for a Split King.
For a Cal King, Nectar suggests 10 x 12 ft and up in a long narrow room, up to 13 x 19 ft. That shape lets the extra length breathe without blocking closets.
Leave about 2 ft around three sides if you can. That is your zone for dressing, changing sheets, and chasing the remote.
Now think delivery path. A king is a big rectangle to steer through halls, stairs, and tight corners.
Measure doorways, stair turns, and elevator openings before ordering. A mattress in a box bends better than a rigid frame, but your frame and headboard may not.
What about frames? Use a sturdy king frame or adjustable base rated for king weight and size.
For a Split King, you need a split king adjustable base or two Twin XL adjustable bases side by side. A solid single king platform defeats the independent recline.
Slats should sit close together with center support for a one piece king. Check Nectar frame guidance at checkout so the warranty stays intact.
Sheets trip people up. Standard King takes standard king sheets.
Cal King needs Cal King sheets. Do not assume king sheets will stretch those extra 4 inches without a fight every laundry day.
Split King needs two Twin XL fitted sheets, plus split king bedding or separate top bedding per side. Many couples use two Twin XL fitted sheets with one shared king top sheet for the best of both worlds.
That quick price check helps while you measure, since Nectar often discounts bedding and frames with the mattress.

Nectar King FAQ
Got a tape measure and five more tabs open? These are the exact questions shoppers ask about Nectar king sizes.
What are the dimensions of a Nectar king size mattress?
A Nectar Standard King is 76 x 80 inches, or 193.04 x 203.2 cm. A Nectar California King is 72 x 84 inches, or 182.88 x 213.36 cm.
A Nectar Split King is two Twin XL mattresses at 38 x 80 inches each, which combine to 76 x 80 inches total. That matches the Standard King footprint but sleeps as two independent sides.
Is a California King bigger than a King?
No, it is not bigger in any useful sense. It is only shaped differently.
A California King is 4 inches longer and 4 inches narrower than a Standard King. Tall sleepers gain legroom, but couples give up a little shared width.
What is the difference between a split king and a king?
A Standard King is one mattress with one sleep surface. A split king is two Twin XL mattresses that together equal a king footprint.
The split setup lets each side recline independently on an adjustable base and can allow different firmness per side. It also offers the strongest motion isolation of the three king types, which helps light sleepers.
Does Nectar make a split king mattress?
Yes. According to Nectar, it offers a split king made from two Twin XL mattresses.
It is built for adjustable bases and independent settings per side. That makes it a strong pick when partners keep different hours or want different recline positions.
How do you keep split king mattresses together?
Start with the right base. A split king adjustable base or two snug Twin XL bases keeps the halves aligned better than a flat king frame alone.
Then add a split king connector strap, gap filler, or bridge pad made for split setups. Tight Twin XL fitted sheets also help hold each half in place.
Push the halves together when you change sheets. Small drift is normal, and regular resets keep the center seam from turning into a canyon.
How much does a Nectar king mattress cost?
Based on nectarsleep.com listings on 2026-09-21, the Classic King was $899, the Premier King was $1,099, and the Luxe King was $1,649. Nectar also offers a Hybrid line in king with pricing that varies by model.

Pick California King if you are taller than 6 ft, sleep stretched out, or your room is long and narrow and needs length more than width.
Pick Split King if you want an adjustable base, different firmness or recline per side, or the strongest motion isolation for light sleep.
