A ruler will measure anything smaller than a piece of paper (paper size is not given). If this is not meant by the question, more info is required.
The answer depends on what characteristic you wish to measure: its mass, length, volume etc.
I would use a ruler (metric) but careful to only measure the inside. You could also wet the beaker and place it on a piece of paper (rim down). This will leave a wet ring that you can measure. But be sure only to measure the dry inner part of the ring.
a piece of paper, and a ruler
It really depends how big the piece of paper is, but a good idea would be square centimetres.ExamplesA0 paper is such that it has an area of 1m2 or 10000cm2.A4 paper has an area of 1/16m2 or 625cm2.
get a ruler,measure it and write it on a piece of paper.
