Booking a Level Run, step by step
Rise and fall method. The check is three equal differences.
- Book each readingBacksight, intermediate or foresight, one line per staff position.
- Work out rise or fallCompare each reading with the one immediately above it.
- Carry the reduced levelsAdd a rise or subtract a fall from the previous reduced level.
- Total the four columnsBacksights, foresights, rises and falls, each summed.
- Apply the checkΣBS − ΣFS = Σrise − Σfall = last RL − first RL.
- Close on a benchmarkCompare with the known level, then distribute the misclosure.
The check in numbers
- ΣBS 4.215, ΣFS 3.100
- Difference = +1.115
- Σrise − Σfall = +1.115
- Last RL − first RL = +1.115
Educational reference. The check proves arithmetic only. A misread staff still balances perfectly.

- Who is the Booking a Level Run poster for?
- Booking a Level Run belongs to the Civil Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning surveying can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Booking a Level Run poster?
- Reducing a field book, and proving the reduction before leaving site. A wall chart earns its place by being glanceable from where the work is happening, so Booking a Level Run belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
- What other posters go with Booking a Level Run?
- Areas & Volumes, Bearings and Contours sit alongside Booking a Level Run in the Civil Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Areas & VolumesBearingsContours
- Is the Booking a Level Run poster free to download and print?
- Yes. Booking a Level Run downloads as a free PDF with no account, no email and no watermark, like everything else in the Civil Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Booking a Level Run poster print at?
- Booking a Level Run is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Booking a Level Run loses nothing.Printing guide
