Look for the first change in shape

When it spreadsWhat to look forFirst check
During the rest after preshapingThe round relaxes a little and stays rounded, or quickly flows into a flat mass.A little relaxation can help final shaping. If it flows, check how it held together through the last fold and at the end of bulk.
Immediately after final shapingThe skin never tightens, the seam opens, or the dough tears with another pull.Check whether the shaping method had enough grip and whether the dough still has strength.
When turned out of the basketIt releases evenly and then flattens, or part of it catches and stretches on the way out.Note the release separately from the proof. Review dough condition and time in the basket, and check whether it stuck.
After scoring or during transferThe loaf held shape after release, then opened or slumped during handling.Check scoring and transfer as well as proof. Have the oven and loading setup ready before turn-out.

A basket supports the loaf during proof, so a loaf can look tall while it is still in the basket. Check whether it releases cleanly and how long it holds its shape after release. A slight relaxation is common. Rapid flattening or obvious tearing gives you a more specific observation to work with. [2] [1] [3]

If it spreads on the bench

For a round wheat loaf, use the recipe’s shaping method and a bench scraper where helpful. Leave enough friction on the work surface to build tension. If the dough tightens with gentle handling, stop before the surface tears and transfer it to its basket. If it never gathers, check whether it was loose from the first mix or became weaker only towards the end of bulk. [1] [4]

If it was loose and sticky from the first mix after a flour or water change, return to the original flour blend or try one measured water adjustment where the recipe allows. If it started with strength and weakened late, keep the formula and compare actual dough temperature, rise and handling at the end of bulk. That sequence helps separate dough strength from the effect of another tightening pass. [5] [6]

If it spreads when you turn it out

If the dough stretches because part of it sticks, first check the basket, liner and dusting recommended for your formula. If it releases smoothly and immediately flattens, compare the condition at shaping with the time and temperature of the final proof. A fragile loaf that looked strong when shaped gives you a different lead from a dough that never held tension on the bench. [4] [2] [3]

Imagine two loaves. One begins flattening immediately after final shaping, even before it enters the basket. The second holds on the bench and spreads on release the next morning. Photograph the first at shaping and just before transfer. For the second, photograph the release and record the proof conditions. On the next bake, change the shaping or formula variable supported by the first record. For the second, choose between a release adjustment and a proof adjustment based on what actually happened.

Crispy Crust’s planned photo log would keep a shaping photo and a turn-out photo beside the corresponding dough and proof notes. Putting those moments side by side would show whether a flat result began on the bench or only appeared the next day.
