Drywall Time Calculator

Enter the sheets and their size, whether a professional crew or you do the work and how many people, the finish level, the drying time per coat and the working hours per day, and this calculator gives the hours of work, the calendar days and the time each stage takes.

It shows why drywall takes a week whatever the size of the crew: the hanging scales with people, the drying does not, and every finishing pass waits for the last one to dry.

  • Hours per sheet are our estimates, not a standard: about 1/3 person-hour to hang a 4 × 8 sheet for professionals and about 1 hour for a careful DIYer, and a fraction of that per finishing pass. Larger sheets take proportionally longer each and fewer of them.
  • Most of a drywall schedule is drying time. Each coat of ready-mixed compound needs about a day at 70 °F and 70% humidity (USG), longer when cold or damp; the drying time calculator adjusts for conditions.

Understanding your result

The headline is calendar days from the first sheet to a sanded wall ready for primer, and the line under it gives the hours of work and the crew. The tiles split the hours into hanging, finishing and sanding, and the bars show the days each stage takes.

The table shows the calculation by stage: hours per sheet times sheets, divided by the crew, for hanging and for each finishing pass; the number of passes for your level, each followed by the drying time; and the sanding. Drying is the long bar. The calendar counts a finishing pass as the longer of its work and the drying that follows, so on small jobs the drying sets the pace and on large jobs the work does.

For dated milestones from a start date, use the project schedule. The drying time for your room’s conditions comes from the compound drying time calculator; and whether your hours are worth spending is the DIY vs pro calculator’s question.

How we calculate this

hanging hours = sheets × hours per sheet × (sheet area ÷ 32) ÷ crew pass hours = sheets × hours per pass per sheet × (sheet area ÷ 32) ÷ crew passes = by finish level: Level 2 two, Level 3 three, Level 4 four, Level 5 five calendar days = ⌈ hanging days + Σ max(pass work, drying) + last drying + sanding ⌉ hours per sheet = professional 0.33 hang, 0.12 per pass, 0.10 sanding; DIY 1.0, 0.30, 0.25

The hours per sheet are our estimates, labelled as such; they are consistent with published hanging times of half an hour to an hour and a half per sheet. The passes per level follow GA-214 as used throughout the site, listed in the levels of finish table. Drying per coat defaults to the manufacturers’ guidance of about 24 hours in normal conditions; setting compound for the tape coat removes the first wait.

The calculator does not include delivery, framing or electrical inspections before the board goes up, texture, primer and paint, or weekends. Cold, damp basements can double the drying time; the drying calculator adjusts for that. Why the schedule is mostly drying, and how setting compound changes it, is in the guide to drying times between coats; planning a DIY job around weekends is in the hang it yourself guide. What those hours cost when a crew does them is in the guide to what drywall contractors charge.

Two worked examples

A 12 × 12 room alone: 17 sheets, DIY, Level 4

  • Hanging: 17 × 1.0 = 17 hours, 3 working days
  • Each pass: 17 × 0.3 = 5 h 6 min; four passes, each followed by a day of drying
  • Sanding: 4 h 15 min
  • 9 calendar days, about 42 hours of work

Most of the nine days are drying. Working evenings after the hanging weekend, the finishing fits around a working week.

120 sheets, three professionals, Level 5, setting tape coat

  • Hanging: 120 × 0.33 ÷ 3 = 13 h 12 min, 2 days
  • Each pass: 4 h 48 min; five passes with no wait after the setting tape coat
  • 8 calendar days, about 41 hours of crew work

The crew works about five days of the eight; the rest is drying, which is why finishers run several jobs at once.

Where to find your inputs

Sheets and size. From the sheet count.

Crew. How many people hang and finish.

Level. The finish level the room needs.

Drying. 24 hours in a warm, dry room; 36 to 48 in a cool basement; less with good airflow.

Common mistakes

  • Planning by the hanging day. The finishing is the week.
  • Recoating damp compound. It shrinks and cracks. Wait.
  • Heating the wall directly. It dries the surface and cracks the coat. Warm the room.
  • Thick coats to save passes. They take longer to dry.
  • No setting compound when time is short. It saves a day.
  • Forgetting primer. Sanding is not the end; prime before paint.

Questions people ask

How long does it take to drywall a room?
For a 12 × 12 room with about 17 sheets, a two-person professional crew hangs it in half a day; taping and three coats at Level 4 take about four days of drying with short visits; sanding and priming add half a day. About a week from bare studs to paint. A first-time DIYer working alone should plan two weekends or more.
How many sheets of drywall can one person hang in a day?
Our estimate is about one sheet per hour for a careful first-timer and about three per hour for a professional, so 8 to 25 sheets a day. Ceilings, large sheets and cut-up rooms are slower; a two-person crew with a lift is much faster on ceilings.
Why does drywall finishing take so long?
Each coat of ready-mixed compound must dry before the next, about 24 hours per coat at 70 °F and 70% humidity (USG), and a Level 4 finish has four passes. The work in each pass is short; the waiting is the schedule.
How can I speed up drywall finishing?
Use setting-type compound for the tape coat so the next coat can go on the same day, keep the room warm and the air moving with a dehumidifier in damp weather, and keep coats thin. Heaters that blow directly on the wall cause cracking; warm the room instead.
How long does a 2,000 sq ft house take to drywall?
About 250 to 350 sheets, which a large professional crew hangs in two to four days; finishing to Level 4 then takes about a week to ten days, mostly drying. Two to three weeks is common for new construction including texture and primer.
Does a bigger crew finish faster?
It hangs faster and does each pass faster, but it cannot make compound dry faster. Past a certain size, extra people wait for the walls.
